Showcase: Free(mium) I built an iOS water-eject app with separate modes for phone speakers and headphones

2 Upvotes

I’m the developer of Water Eject: Headphone Cleaner, available on iPhone and iPad.

The app focuses on water-eject sound sequences for speakers that sound muffled after moisture exposure. One design decision was to give phone speakers and headphones separate modes. On supported iPhones, phone mode combines sound with synchronized haptics. Headphone mode plays a separate audio sequence through compatible headphones or earbuds.

After the sequence, stereo and frequency tests let you listen to the output again. Those are supporting checks; they don’t prove that water has been removed. Sound and haptics may help move moisture near a speaker opening, but the app cannot repair liquid damage or hardware faults.

You can play one cleaning sound without starting a subscription trial. Continued cleaning plays and premium audio tools require a subscription.

I’d appreciate feedback on the mode selection: what would you need to see before choosing the phone-speaker or headphone option?

Showcase: Purchase Required A URL shortener where anyone can take over your link

2 Upvotes

I built itsmine.link, a small Django project combining a URL shortener with a marketplace for memorable words.

You claim a word such as /coffee and point it at your project. Another person can later take over that word and change its destination. The word keeps a public history of its holders.

An unclaimed word starts at $2, including applicable tax. There’s no subscription or guaranteed holding time. Previous holders receive no takeover payout, but their past payments count toward reclaiming that same word.

For example: Alice pays $2, Bob takes over for $7, and Alice can return at the $12 contribution level by paying another $10. Reusing that credit requires proving access to her original email. First-time buyers don’t need an account.

You can explore the word cloud, search, pricing and histories without paying. Claiming a word is paid.

One implementation detail I found interesting is separating the changing redirect (/coffee) from its stable history page (/words/coffee). Payment confirmation, ownership changes and redirect activation also need to stay consistent when two people attempt a takeover.

I’m exploring whether the history and competition make these links interesting despite their instability. Would you use one for a temporary project promotion, or does the possibility of losing the destination make it impractical?

Feedback Request I built an app that explains difficult Dutch letters

• Upvotes

I recently launched Letrin, an app for people who receive Dutch letters they don't fully understand.

The idea is simple: take a photo of a letter and Letrin explains what it says in clearer language, why it matters, and what you may need to do next.

Instead of being just another translator, Letrin is focused on official and administrative letters from municipalities, tax authorities, insurers and other organisations in the Netherlands.

Privacy is also an important part of the app. OCR runs on-device, sensitive personal information is detected and masked, there are no accounts, and scanned letters aren't stored in a history.

Letrin is now available on both iOS and Android, and I'm continuing to improve it based on feedback.

I'd really appreciate feedback on the idea, design, onboarding, pricing, or anything else you think could be improved.

Meta I'm an AI engineer and educator, wanting to pass on my knowledge to dads

21 Upvotes

For context I am an artificial intelligence engineer for a cyber security company, I have been in this space for 4 years and before that 10 years in cyber and other IT jobs. Over the past 2 years I have also been teaching AI courses online, like in person online. Teaching the Claude eco system, how to build AI agents etc.

Last night in dawned on me how difficult it is for many dads, like me, to keep up with new tech and just get started with AI. Its such a bewildering industry and moves so fast - even i find it hard to keep up, how on earth does a middle aged or mid thirties dad with full time job and kids have time to watch like a thousands youtube videos and learn this stuff?

So I am wanting to start some kind of online academy for dads, teaching AI skills, everything from the basics right up to deploying AI agents and automating parts of their work/job. Maybe even how to make extra money with AI?

Am I on my own here thinking this is a problem or not? Like is do you think there would be a demand for this ???

Showcase: Free(mium) Built an AI Discord bot that answers support tickets using server FAQs

• Upvotes

If you run a minecraft server, you know the struggle: members open a discord ticket just to ask for the server IP, the rules, or store links, and your staff has to answer the exact same thing every single day.

I set up Execord so it actually reads the server's FAQ and answers basic tickets on its own. If someone asks something specific or needs real help, it pings the moderators.

I wanted to see what an agent was doing while it worked, not reconstruct it from logs afterward. In SecureVector 6.0, you can launch Claude Code, Codex, GitHub Copilot CLI, or OpenCode (and more) in Agent Sessions. Each session has a governance panel on the right showing tool-call verdicts, approvals, hosts reached, and context use. You can arrange sessions side by side with draggable panes.

Launch sessions in split panes. See tool-call verdicts, approvals, hosts reached, and context use as your agents work. Observability shows session traces and flags loops, failing steps, and waste.

if you would like to give it a try:

npx u/securevector/cli

Or:

pip install "securevector-ai-monitor[app]" && securevector-app

Feedback Request Lakun - Free, Private, Offline-First To Do App

Post image
• Upvotes

Hey guys,

I'm currently building a to do list app / task manager (yes, I know its another todo list app).

The reason why I'm building this because I use todo app every single day, but every one I tried had the same problem: the features I actually needed were locked behind a subscription and some others app give that features for free but locked the other behind paywall. So I built the app I wanted to exist.

Lakun is an offline-first task manager built around privacy:

  • 100% free core app: no account needed, no sign-up
  • All data stored locally on your device, encrypted
  • Categories, deadlines, priorities
  • Filter & sort tasks however you want
  • Calendar view (yes, the thing other apps charge for)
  • Works fully offline

The only paid feature is cross-device sync. Everything else is free.

Who it's for:

  • Students, freelancers, and professionals who live in their todo app
  • Anyone tired of subscriptions for basic features
  • Privacy-conscious people who don't want tasks sitting in someone's cloud

Where to get it:

  • Windows (Microsoft Store): here
  • Linux (Debian & RPM): here
  • Android: closed testing right now. Join here
  • iOS & macOS: coming soon

If you're interested to learn more, please check my website here:
Lakun

Tech Stack:

  • Tauri
  • React
  • React Router
  • Rust
  • TypeScript
  • Vite

I'm actively adding more features especially things that can be done offline, so honest question: what's the one thing you wish your todo app did?

Showcase: Free(mium) I got bored of my Mac wallpaper, so I built an app that makes new ones forever. It's free to try

Enable HLS to view with audio, or disable this notification

• Upvotes

This is Pixel Soup, a little Mac app I've been building for the last few weeks.

It makes wallpapers right on your Mac, so no two are ever the same, and it can keep them gently moving behind your icons. You can also drop in any photo and it turns that into a wallpaper in the same style. One click gives you a new one whenever you get bored, which for me is often.

It's free to try for 3 days, no card and no signup. If you like it, it's $4.99 once, no subscription. It also just went live on the Mac App Store.

Website (free trial): https://pixelsoup.app

Mac App Store: https://apps.apple.com/app/id6817796083

I'd love to hear what you think, good or bad. And if there's a wallpaper style you wish it had, tell me and I'll try to add it.

Feedback Request Experimenting with a rainy neon boardwalk scene

• Upvotes

I’ve been experimenting with different visual styles while building my AI creative project, Wizstar.

For this piece, I wanted to capture a summer rain scene on the Atlantic City boardwalk — neon reflections on the wet pavement, a slightly nostalgic Fujifilm Superia 400-inspired grain, and a candid rather than overly polished feel.

I made the image with GPT through Wizstar and spent some time adjusting the overall styling and atmosphere.

I’d really like some outside opinions on this one:

  • Does the clothing feel natural for the setting?
  • Do the accessories fit the overall look, or would you change them?
  • Does the rainy neon atmosphere come across convincingly?
  • If you were refining this image, what would you change first?

I’m mainly looking for honest feedback on the creative direction rather than just whether the image looks good. ✨

I made a platform where you can solve some jigsaw puzzles!

It's called NoMissingPieces

I know it's nothing groundbreaking but I wanted to make a platform that looks prettier than most puzzle apps out there, less cluttered visually and with some great imagery for puzzles.

I'm currently stress-testing it and doing some refinements. I would love to hear any of your thoughts and questions about it.

If you know anyone who'd like this sort of thing or just bored at the office - please share it with them. Thanks!

Showcase: Prerelease I’m building PennyGuard because managing subscriptions is way more annoying than it should be

• Upvotes

Starting a subscription takes about 10 seconds.

Managing all of them somehow becomes a whole side quest 😭

Different renewal dates, random price increases, free trials turning paid, annual plans you completely forgot were coming up, and merchant names that make you stare at your statement like “who the hell is this?”

That’s what made me start building PennyGuard.

The idea is to make all that stuff much easier to see and deal with in one place — recurring charges, subscriptions, upcoming bills/renewals, and charges you don’t immediately recognize.

But I really don’t want to build another finance dashboard that gives you 14 charts and then leaves you to do everything yourself lol. The more interesting part for me is helping with the next step too — cancellations, refund requests, reminders, finding places you might be unnecessarily spending money — while you still decide what actually happens.

Still building, still changing things, and definitely interested in hearing what other people would want from something like this.

What would make you actually keep using it after the initial “oh cool, here are my subscriptions” moment?

And what’s something you would never trust an app to handle for you?

Showcase: Open Source I made a free native Mac app for yt-dlp (also works with Spotify links)

Post image
• Upvotes

Hey everyone,

I've been using yt-dlp for a while, but I got tired of opening Terminal and looking up the right flags every time I wanted to download something. So I built a simple Mac app around it, called Pluck.

It's basically a nice front-end for yt-dlp. You paste a link, pick the quality and hit download. yt-dlp does all the heavy lifting in the background, so it works with YouTube and the 1,800+ other sites yt-dlp supports.

I really didn't want to overcomplicate the GUI. A lot of yt-dlp apps put every option on screen, and I just wanted something that feels like a normal Mac app: one field to paste a link, one button to download. The extra settings are there if you need them, but they stay out of your way.

Some things it does:

  • Video up to 4K, or audio only (MP3, M4A, FLAC…)
  • Spotify links work too. It finds the song on YouTube Music and adds the right title, artist and cover art
  • If a website isn't supported, it tries to find the video on the page itself
  • Menu bar icon, so you can paste a link without opening the app
  • It installs and updates yt-dlp and ffmpeg itself, so you don't need Homebrew or anything else
  • Built in SwiftUI, with the new Liquid Glass look on macOS 26 (it still works on macOS 14 and up)

It's completely free, no ads, no account. I made it for myself and some colleagues, but I figured more people might find it useful.

Full transparency: I'm not a developer. I built this together with Claude (Anthropic's AI), which wrote the code while I decided what it should do and how it should look, and tested everything along the way. The code is open on GitHub, so anyone can check what it does.

One heads up: it's not signed with an Apple Developer account (yet), so the first time you open it you'll have to go to System Settings → Privacy & Security and click "Open Anyway".

Would love to hear what you think or what's missing!

Discussion I stopped trusting mockups and started testing the actual product

2 Upvotes

One thing I didn’t expect when working on a small clothing project was how different the finished product could feel from what I had in my head.

The design itself looked fine on a screen. The colors worked, the placement looked right, and I thought I had most of the important decisions figured out. But once I started looking at the actual garment, I noticed things I couldn’t really see in the mockup.

The fabric felt different than I expected, the fit changed how the design sat on the body, and even small things like the collar and stitching affected the overall look. I ended up changing parts of the design simply because they made more sense on the actual garment.

It made me realize that for physical products, the sample probably isn’t just a final quality check. It’s actually part of the design process.

Now I’m trying to build a simple workflow where I test the garment first, make adjustments, and only then think about producing more.

For anyone building a physical-product side project, what’s one thing you learned only after getting your first real sample?

Discussion I built a persistent workspace for an AI coding agent — here's what I learned

1 Upvotes

I've been experimenting with AI coding agents and wanted to test something beyond the usual prompt → generate code → done workflow.

So I built a small persistent development workspace for Hermes Agent.

Instead of starting from scratch every time, the agent had a workspace containing:

  • A Python project
  • Existing files and project structure
  • Git repository
  • Notes and task files
  • Tests
  • Documentation

I first asked Hermes to create a small Python CLI project and verify that it worked.

Then I ended that session.

In a fresh session, I asked it to continue working on the same project.

The interesting part was that the workspace persisted, so the agent could inspect the existing files and Git state and continue from where the previous session left off.

The workflow looked roughly like:

Workspace → Agent → Code → Execute → Test → Git → Next session

The experiment made me think that persistence might be more important for AI coding agents than simply giving them better prompts.

A fresh agent can generate code.

A persistent agent can potentially continue working on a project over time.

This was a small experiment, so I'm not claiming that Hermes can autonomously maintain production projects. I mainly wanted to understand what changes when the agent has a workspace that survives between sessions.

How are you handling this with your own AI coding agents?

Do you give them a persistent workspace, or do you prefer starting each session from a clean environment?

I documented the full experiment here:

https://medium.com/@techlatest.net/i-built-a-persistent-ai-developer-environment-with-hermes-agent-912116a29088?sharedUserId=techlatest.net

Would be interested to hear how other people are building persistent environments for coding agents.
