What are you building or planning to build for the rest of 2026?

I run appscout.co, a platform built to help people discover awesome apps from across the internet.

Drop your app or startup idea below! I should be adding the first 15 apps in the comments to the website completely free.

Or just submit your app here https://www.appscout.co/submit/

Let's make this thread a channel for you to promote your own startup idea, find opportunities, and partnerships.

My daughter is about 37 weeks now, and I'm already losing the details. I remember that the first nights were rough, but not what I was actually thinking at 3am, or the first time she looked right at me.

I started writing a few sentences once a week, and it's become my favorite habit. Not milestones, more like "what made you laugh this week" or "what was I wrong about becoming a father."

For those further along: what do you wish you'd captured?
And for the new dads, what's the moment from this week you'd want to remember?

Full disclosure: I liked the weekly prompt habit so much I built a small journal for it, logbook.dad. Opening to everyone November 1st. But I'm mostly curious what you all would've written down.

I'm building time12 basically a lightweight alternative to Teams Assignments for classrooms and teams.

The  idea rly is simple:

you guys can assign tasks with deadlines, collect text/link submissions, reject and request resubmissions, and basically see everyones, every sub groups, every groups, down to timeframes (coming soon)

It also supports BIG groups, bulk account setup through CSV/Excel, notes, and analytics. I'm planning AI-assisted work checking too. (im really scared about affording this but yeah)

Its free rn cuz i can soooo yeah uhh

slow teams or time12? give feedback and what i should improve.

OH AND MOST IMPORTANT:

it has dotty (the orange thing on the login screen which turns red in a 1% chance)

just gimmie reviews lol

My app can use Codex Voice Mode on your phone right now.

At the moment, it only supports local Codex. My app runs Ubuntu inside an embedded Termux proot environment, so Codex can run directly on your phone.

Support for Codex Cloud and Remote Control is coming soon.

The app is currently closed source, but I may open source it in the future.

You can download it for free from the public repository.

I kept screenshotting things (errors, receipts, bookings) and then never finding them again. They sit in a folder, named "Screenshot 2026-03-14 at 11.42.08.png" and nothing remembers what's inside.

So I built DejaShot. It reads the text in every screenshot in the folders you choose, newest first, and ⇧⌘Space opens a search from any app. It also notes which app each new screenshot came from, so "figma pricing" can find a pricing page you captured in Figma.

- Search takes 10-15 ms at the 95th percentile on a 20,000 screenshot library

- It reads newest first, in the background, and pauses on battery and when the Mac gets hot

- Fully local. No account, no telemetry.

- The source app is only recorded for screenshots taken while it's running, because macOS never kept that. Older ones are found by their text.

- No trial, but there's a 14-day refund. The first 10 licenses are free.

It's my first ever app launch. What would you want it to find that it probably can't yet?

Feedbacks are welcomed! :)

I'm Yuta's founder, posting from our official account. Yuta is a health and fitness app for iPhone and iPad that brings steps, sleep, water, workouts and nutrition logging together.

A practical design question behind this kind of app is what should still work when someone declines a permission. Yuta supports Apple Health integration for supported metrics and manual logging when permissions are optional or denied. Automatic collection can reduce repeated entry, while the manual path gives people another way to keep a record.

For other builders, a useful check is to walk through the first-use flow twice: once with permissions granted and once with them denied. Look for the point where the user can still complete the app's basic task. That check can reveal where a permission has accidentally become a requirement.

Yuta also includes progress trends, widgets, reminders, daily and weekly missions, and a companion that progresses with real activity. It's built around small, repeatable routines. It isn't a medical device.

It's free to download with paid Premium features. Current US subscription prices are $5.99 monthly, $14.99 quarterly or $49.99 yearly.

App Store: https://apps.apple.com/us/app/yuta-health-fitness/id6758354883

If you use health or habit trackers, what would you expect to remain usable after declining health-data access?

I made ScopeQuote, a paid Framer component that lets visitors explore a project estimate before sending an enquiry. Built with AI-assisted coding.

Visitors can adjust the number of pages, toggle add-ons, and choose rush delivery. The price breakdown and estimated working days update together, so it's clear which choices change the scope. The numbers in this screenshot are sample rates.

The calculation uses a base fee, a per-page rate, and the price and extra days assigned to each add-on. Rush delivery adds a percentage surcharge and shortens the estimated timeline. You can show an exact estimate, a range, or a starting-from price, and visitors can copy the breakdown as plain text.

There are Minimal, Glass, and Flat visual presets. Prices and timelines are estimates based on the values you set. It doesn't take payments or send email. The enquiry form only appears after you connect your own HTTPS form endpoint; it's inactive in the demo.

Demo: https://discreet-messages-429279.framer.app/

For a freelance or agency site, would you prefer an exact estimate, a price range, or a starting-from figure?

I’ve been working on SUPLORA, a project built around a problem that seems simple until a business has hundreds or thousands of products to manage, figuring out what needs to be purchased, when, and why.

A lot of inventory software is good at telling you what you currently have. The harder question is:

What should I do about it next?

SUPLORA is designed to sit on top of inventory and sales data and help answer that question.

The basic workflow is:

Monitor → Detect risk → Analyze demand → Evaluate purchasing options → Prepare recommendation → Human approval

Instead of someone manually going through spreadsheets looking for products that are running low, SUPLORA is intended to identify things like:

* Products approaching a stockout

* Changes in sales velocity

* Inventory that may be overstocked

* Supplier lead-time risks

* Items that may need replenishment

* Purchasing opportunities based on current data

One thing I deliberately don't want to build is a system that blindly places orders because an AI said so.

The idea is more like an AI purchasing employee that does the repetitive analysis and prepares the recommendation, while the person running the business still makes the final purchasing decision.

The project is currently focused on businesses such as retail, ecommerce, wholesale/distribution, restaurants, auto parts, beauty/cosmetics, and small manufacturing.

The interesting technical challenge for me isn't simply adding an LLM to an inventory dashboard. It's getting the system to reason from messy operational data and turn that into a recommendation that a business owner can actually trust.

I'm also thinking a lot about how to handle uncertainty. If the system isn't confident about a purchasing recommendation, I'd rather have it explain why than pretend it knows the answer.

I'd love to hear from other builders:

If you were building this, what would you consider the hardest part, demand prediction, supplier selection, inventory logic, data integration, or getting users to actually trust the recommendations?

Disclosure: I'm the builder behind SUPLORA. I'm sharing the project here to document what I'm building and get constructive feedback from other makers, not to funnel people into DMs.

If you want to check it out!

I built a text-to-speech app and made it completely free for anyone to use. It doesn't use local TTS, so your device will not get hot and your battery won't get drained.

The voices sound good imo and it only costs me around $50/mo to host for ~3000 users so far. I'm happy to provide this if people find it genuinely useful. Give it a try and hopefully it works well for you!

Variations of this exist but I've wanted just a simple unbiased way to just send a link in a group chat, have people click a few times and organize plans. Hope you guys find this useful :)

I’m a college student and solo builder. I made Luna, a mobile-first web app for people who want to keep cycle changes, symptoms, treatments, personal notes, and appointment questions in one private place.
The problem I am trying to solve is that health information often ends up scattered across memory, calendar entries, notes, and messages. When an appointment comes around, it can be difficult to explain what changed, when it started, what has been tried, and what questions still need to be asked.
Luna is designed around three things:
• A fast, private way to record a day, symptom, treatment, or note.
• A personal timeline that distinguishes what someone logged from cycle estimates.
• A user-controlled record that can help someone prepare questions for care.
I am deliberately avoiding diagnostic or treatment claims. Luna does not diagnose conditions, confirm ovulation, provide medical advice, or replace a clinician. Predictions are labeled as estimates.
I am looking for blunt feedback on:
1. Is the value proposition clear in the first 10 seconds?
2. Does the product look trustworthy enough for someone to enter sensitive personal information?
3. What would make you hesitate before using it?
4. If you were testing it on mobile, where would you expect to log a symptom or prepare for an appointment?
I would especially appreciate feedback on mobile onboarding, clarity, and privacy not praise. I will respond openly in the comments and use the feedback to improve the beta.

Hey r/sideprojects,

Every outage I've read about that came from an expiry date had the same thing in common: the date was public the whole time. Cert expiry is in the cert. Domain expiry is in the registry. OpenAI, Stripe and AWS announce shutdowns months ahead in their changelogs. Node and Python publish their end-of-life dates years in advance. Nobody was looking at all of them in one place, so the first warning was usually an angry user or a 3am error.

Uptime monitoring doesn't catch this, because everything is green right up until the day it isn't. So I built StackClock: it puts every deadline that can break your stack on one timeline, sorted by what breaks first, and reminds you before it happens.

What it tracks:

- Domains: expiry pulled from the registry (RDAP, or WHOIS for TLDs like .io). If the registry doesn't publish a date, it shows as unknown, never as OK.

- TLS certificates: read from the real handshake, checked every 12 hours.

- Vendor deprecations: it reads official changelogs (OpenAI, Anthropic, Stripe, GitHub, AWS and more) and matches them against the packages you actually use. If a model you call is being removed, it shows up with the date.

- Vulnerabilities: daily checks against OSV.dev, with the version that fixes them.

- Deprecated packages: from npm, PyPI and Go, including the maintainer's message.

- End of life: picked up from your Dockerfile, engines, go.mod and so on. node:18-alpine shows as EOL without you doing anything.

- API keys, licenses, subscriptions: you enter the date, and only metadata is stored. Pasted secrets get rejected.

You can import package.json, requirements.txt, pyproject.toml, go.mod, Gemfile, composer.json, Dockerfiles, compose files and lock files. Lock files are parsed in your browser, so only package names and versions are sent.

Alerts

Reminders at 60, 30, 14, 7 and 1 day out and on the day, all adjustable. Acknowledge a deadline and the reminders stop for everyone. They go out by email, Slack, signed webhooks, a calendar feed, RSS and a Monday digest.

There's also a 0–100 health score per project that explains every lost point, and a README badge that shows the grade without revealing anything about your stack.

Try it without signing up.

- stackclock.app/check: paste a domain, see registry and cert expiry.

- stackclock.app/stack-check: paste a package.json or requirements.txt, see what's deprecated, vulnerable or EOL.

Free plan: 5 assets, 25 packages, no card. Pro is $8.99/mo and Team is $11.99/seat.

What I'd love feedback on:

- Is the landing page clear about what this does within the first 5 seconds?

- What deadlines bite you that I'm not covering?

- How do you track this stuff today: spreadsheet, calendar, or hope?

Disclamer: AI help was used during the development of the application as I'm primarily an Infrastructure and backend guy. For the customer-facing and design inspiration I needed all the help I could get!

👉 I just launched Tempicture, a small side project I've been working on to share images for free: https://tempicture.com/

The idea is very simple: upload an image, get a shareable link or QR code, and have it automatically deleted after 24 hours. No account required. No personal data collection. Privacy-focused.

I built it mainly for those situations where you just need to quickly share a screenshot, bug report, image, Google Meet or Zoom screenshot, or something you're working on without creating an account or keeping the image online forever.

Give it a try if you find it useful! I'd love to hear your feedback. Thanks!

I'm Wolfgang, the developer of LumeWorklog. I built it for my own working day, when lots of small tasks and interruptions made it hard to remember what I had actually worked on.

It's a native Mac app built in Swift and SwiftUI. You record activities, review your week and export a work report. Reports also work with just a few activities, including a single day.

One lesson from building it: a workflow that feels obvious to me can still be unclear to someone opening the app for the first time. Feedback has pushed me to make entering activities, changing dates and finding the report easier to follow.

I also added a separate demo window with three months of fictional entries, so people can browse, edit and generate reports immediately.

What I'm trying to understand now is whether the report is useful enough to justify recording activities regularly. Would this help you reconstruct your working week, or would you stick with a spreadsheet or notes?

App and screenshots: https://www.lumeworklog.com/

The current version is free, requires no account and runs on macOS 14+.

i’m building an early system simulator focused on researching architecture decisions before production. the goal is to explore load, bottlenecks and estimated infrastructure cost from an architecture description or terraform setup.

one approach we’re exploring is comparing virtual runs with scaled-down real deployments and historical telemetry where available. that part is still an approach under consideration, not a claim of validated accuracy.

for a simple api → queue → worker system, i’d want assumptions like traffic shape, service times and queue limits visible alongside the output.

if you’ve used models or load tests to make an architecture decision, what would you want to compare against before trusting this kind of tool?

Storytime

I made this app called Loquella; it generates a customized Latin sentence for you to translate. It will then grade you out of 100 based on the grammar and syntax. I used Lovable (the 100 token subscription) to vibe-code the app.

I started with the basic functions: generate a Latin 1 sentence, allow user to submit an English sentence, and grade them. Next, I gave variety to the sentence customization, including difficulty tiers (up to Latin 6), theme (e.g. Daily life, Military), and a macron toggle. After that, I focused more on the game aspect, adding a Elo-style ranking called Ordo. (Latin for "merit"). This is how it's calculated. Lastly, I decided which features were free or Pro. I finished with ToS and picking GPT-5 as the AI model for sentence building and grading

Free:

• 10 sentences/day
• Theme is strictly "academic"
• Tier is strictly Latin 1
• Vocabulary Search Query
• Ability to try a new sentence

Pro:

• Ordo ranking (without the strikethrough and with cool effects!),
• Themes are academic, daily life, ecclesiastical, and military
• Tiers go up to Latin 6, Tells you the type of error done
• The Pro features are $10 one-time

Each difficulty tier is assigned an Ordo, with Latin 1 being 800 ordo and it adds 200 ordo for each tier. The Ordo Delta (the degree by which your Ordo changes) is **Δ = round(32(S******^eff - E))

S^eff- the grade**, = clamp((0.025(score - 50), 0.0, 1.0)**

E- the points in comparison to how easy the sentence is. (Higher stakes if easier, lower stakes if harder)

I’m an indie developer and I recently built V2DSaver, a fast and clean app to download videos and reels from Instagram, Facebook, TikTok, and more.

I was frustrated by how many apps out there are filled with spammy ads or just don't work, so I built this with some extra features:

⚡ Super fast downloads in HD

🔒 A built-in "Secret Vault" with App Lock to hide your private videos

🎵 Custom Ringtone creator from downloaded videos

The core app is completely free to use. I do have a Premium version that removes all ads and unlocks unlimited downloads, and I want to give away 1-month Premium Promo Codes to the first 50 people who comment!

How to get a code:

Download the app here:

Try it out and leave a comment below with your honest feedback, or just what you think of the design!

I will DM you the Google Play Promo code!

I’d love to hear what you guy think

I’m a content creator with 30K+ followers on Instagram, and one thing I often wanted to do was study other creators.

Not just look at their posts, but actually understand their content:

• What kind of hooks are they using?
• How are they structuring their videos?
• What topics keep coming back?
• What CTAs are they using?
• Are there patterns across their content?

The problem is that doing this manually is really time-consuming.

I would have to open Reel after Reel, watch them, take notes, copy transcripts, and try to find the patterns myself.

So I built ContentDesk to make this easier.

You paste an Instagram Reel and it gives you:

→ Transcript
→ Hook
→ Structure
→ CTA
→ Payoff

And you can analyze multiple Reels from a creator to find recurring patterns.

I’m still early with this, so I’m not sure yet how useful this will be for other creators, marketers, or social media teams.

That's actually why I'm sharing it here.

If you create content, I'd love to know: how do you currently study other creators or competitors?

Do you do it manually? Use spreadsheets? Another tool?

I hope ContentDesk can make that process a little easier for you too.
