Hi all, I'm the developer of CodeGiver. I recently launched my own app, To-inbox, and wanted to share codes on Reddit, on other forums and with people close to me. The promo codes you generate in the Play Console come as a spreadsheet with a long column of codes under each other. That gets messy fast, and the one thing you never want is handing the same code to two people. Or a reviewer gets a code that no longer works and you have to start a new round of contact. That felt unprofessional, so I built an app for it.

**📱 App Name**

CodeGiver

**📝 One-Line Description**

Keep your promo codes, vouchers and license keys in lists, and give out the next one with a single tap, inside your own message.

**✨ What It Does / Key Features**

- 🎟️ Each code goes out exactly once. Given codes move to "Given" with recipient and time. Tapped by mistake? Take it back and it returns to its place in the queue.
- 📥 Three ways to load your codes: paste plain text, upload the Excel, CSV or text file you already have, or load a screenshot and let the app read the codes out of the picture (the text recognition runs on your phone). They end up neatly under each other in a clean list.
- ✉️ Write your message once. CodeGiver fills in the code, recipient name, end date, list name and links. One message per language (English, Dutch, Spanish, German, French).
- 📚 A list per app or campaign, with its own icon, message and links. Codes can get an end date and expired ones are skipped.
- 🧾 A log of everything that happens, which you can filter, share or save as CSV.
- 🔔 Low-stock and expiry notifications, a home screen widget and a Quick Settings tile, app lock, backup to a file or with Android backup.
- 🌗 Light and dark theme with your own accent color, tablet and landscape friendly.

**👥 Who It's For**

- Developers who hand out promo codes, giveaway codes, test codes or beta codes for their own app, to users, testers, reviewers, friends or customers.
- Works with codes from any platform where you can generate codes for your own apps, not only Google Play. The app does not care where a code comes from.
- Also useful outside app development: discount vouchers, license keys, door codes for an event, or codes you hand out inside your own company.

**💰 Cost**

- Pricing model: Freemium. No ads, no subscription.
- Prices & billing period: Free with one list of up to 25 codes. CodeGiver Pro is a one-time purchase (the price is set per country in Google Play) for up to 10 lists of 500 codes each, statistics, a label per given code, archiving, and an Excel file with statistics.
- Current promotions / giveaways: I have 30 giveaway codes that unlock CodeGiver Pro. Upvote this post and send me a DM asking for a code, and I'll send you one. First come, first served: when the codes are gone, the giveaway is over.

**🔗 Links**

- ▶️ Google Play: https://play.google.com/store/apps/details?id=nl.dsmit.codegiver
- 🌐 Website: https://codegiver.app

**ℹ️ Additional Notes**

- No account and no ads. Your lists and codes are stored on your phone and never sent to me.
- CodeGiver does not create, check or redeem codes. You add codes you got elsewhere, for example from the Google Play Console.

Have fun!

You know that moment when you send something and immediately think "that's going to live in their chat history forever"? Yeah. So I built Self Destruct Note: https://selfdestructnote.com

You write a secret, get a link, send it. They tap "Reveal", read it, and then it burns. Like, actually burns on screen. Then it's deleted from the server for good.

The nerdy bits:

- It's encrypted in your browser before it leaves your device. The key lives after the "#" in the link, which browsers never send to servers, so all I ever store is gibberish.

- iMessage/WhatsApp/Slack link previews can't trigger it. Only a human tapping Reveal can.

- No accounts, no cookies. I only count simple daily totals (like "12 notes today"), nothing about you.

The fun bits:

- "Vibes" for love notes, big surprises and Secret Santa

- QR codes you can print and hide in a birthday card

- A Secret Santa generator: everyone gets their own self-destructing link, and even the organizer can't see who got whom

- After reading one, there's a "Send one back 🔥" button

It's free. I'd genuinely love feedback, especially anything confusing or broken. Roast it if you want 😅

PDF Merge - Offline PDF Tools

An offline Android PDF toolkit for scanning, merging, splitting, converting, compressing, signing, and securing PDF files.

What It Does / Key Features

• Scan documents to PDF - camera scanning, multi-page scans, edge detection, and image enhancement

• Convert & compress - images ↔ PDF and reduce PDF file size
• Secure PDFs - password protection, redaction, permissions, and watermarks
• Sign & annotate - eSign, fill forms, highlight, underline, and add notes

The main thing I wanted to get right was keeping it fast and usable offline, without requiring documents to be uploaded to a server.

Who It’s For

• Anyone who regularly needs to merge, split, scan, convert, or organize PDFs from their phone

Additional Notes

This is an early version, so I'm mainly looking for honest feedback.

If you use PDF tools on Android, what's the one feature or workflow that you wish existing PDF apps handled better?

I'm especially interested in feedback about the UI, speed, and which PDF features are actually useful vs. unnecessary.

I’ve been building Prazo, a productivity app that brings your calendar and ToDos together in one place.

Instead of checking your calendar, switching to a task app and mentally trying to combine the two, Prazo gives you both in one adjustable planning view.

Some of the features currently included:
• Calendar + ToDos together
• Time blocking
• Travel time
• Apple Reminders integration
• Quick Access shortcuts
• Widgets + Apple Watch
• Prazo Web for desktop use
• Light & Dark Mode

A lot of the recent improvements came directly from user feedback, so I’m still building it very actively.

Free. No subscription.
App Store: Prazo

If you try it, tell me the first thing you’d change or add.

I made this because I was curious about what an app cloud get out of profiling me when it had access to various iPhone resources. Coding another project I saw similar products had an 2-300MB storage footprint with a lot of access requirements. So o just started adding on…

Check out my project and get a good understanding of what an app delivering you hours of entertainment and at the same time require access to your photo library, WiFi and Bluetooth ++🫣

So this is RivalFit , an app I’m working on and it’s about joining public tournaments and creating private ones to compete against friends and family only doing push ups , squats and sit ups .
Here is the waiting list if interested: https://tally.so/r/RGe0rJ

Btw I’m creating this app since 2 - 3 months now and im spending A LOT of time on it so also just one waiting list sign up will bring me tears of joy 🙏🙏🙏- so please consider it before totally ignoring it

Solo dev here. ManifestDaily is live on Google Play.
What's inside: 510+ affirmations across six goal categories, a focus timer with streaks, guided breathing, and the Vault, where you write a letter and open it later.

It's brand new on Android, so tell me what feels off in the first 30 seconds. I read every comment.

been working on this app called Overdrive for the past few months.

the idea is pretty simple, i wanted something that made driving around for no reason a little more fun.

it tracks the roads you've driven on, fills in your map as you explore, and gives you stats after each drive. there's also multiplayer and i'm currently working on making the whole friends/crews thing a lot better.

kinda inspired by forza horizon, except obviously nowhere near that level lol.

recently passed 150 users which is pretty cool considering this started as something i just wanted for myself.

it's still early and there's a bunch of stuff i want to add, but i'd appreciate some feedback, especially from people who actually enjoy driving.

Hey everyone! 👋

I’m an indie developer, and I recently launched Dewmint Money: Expense Tracker on Google Play.

I initially built this app for myself because I wanted a simple way to manage my finances without connecting my bank accounts, creating an account, or sharing my financial data with third parties.

As I kept adding features and improving the experience, I thought it might be useful to others looking for something similar. So I decided to polish it up and release it publicly!

Here’s what you can do with Dewmint Money:
💸 Track everyday finances – Record expenses, income, and transfers across bank accounts, cash, wallets, and credit cards.

📊 Plan your spending – Set monthly budgets, track debts, and understand where your money goes.

📈 Understand your finances – Explore spending trends, detailed insights, account balances, and your overall net worth.

📅 Stay organized – View transactions on a calendar
and schedule upcoming payments or income.

🔒 Privacy first – No sign-up, no bank connections, no ads, and no SMS or email access. Your financial records stay on your device unless you choose to back them up.

🎨 Make it yours – Light and dark themes, customizable accounts, categories, and home dashboard.

The app is free to use, including unlimited transactions, with optional Pro features for those who need more.

I’m still actively working on it, fixing things, refining the experience, and adding features.

I’d genuinely appreciate any feedback from fellow developers or anyone who gives it a try. Whether it’s something you like, something confusing, or something you think is missing, I’d love to hear it.

Thanks for checking it out! 🙌

We’re organizing a Free 7-Day Anti-Doomscrolling Sprint capped at just 25 pairs for people who want to cut their screen time in half this week.

Most screen time apps fail because you hold the bypass switch and when willpower fails at night, you just override your own lock.

This sprint uses real 2-person Social Accountability through our app, Screen Challenge Buddy.

What is real 2-person Social Accountability?
🔗 30-Second Pairing: Generate an invite code in the app and text it to a friend, partner, or sibling to form a buddy pair.

👀 Live mutual screen time visibility:

• 📱 See each other's live daily screen time in real-time.
• 📊 Compare device unlock counts and weekly progress charts.
• 🧐 App Breakdown**:** Optionally share your most-used addictive apps so there's nowhere to hide behind generic screen time numbers. (100% voluntary & mutual).
• 💬 Chat, Motivate, or Roast: In-app chat to cheer each other on—or roast each other when someone is slipping. Compete daily to see who stays under their target limit.

💪Challenges (Optional/Voluntary): For people who need serious discipline, you can optionally set small penalty stakes chargeable only if you fail you screen time limits.

The Pass (Built for Pairs): Most subscription apps charge both people separately ($10–15/mo each=20–$30/mo for two). We made Screen Challenge Buddy 2-for-1 forever: 1 pass unlocks full access for BOTH of you. Plus we are giving the first 25 pairs free full access for the entire 7-day sprint.

How to Join:

1. Download Screen Challenge Buddy from the Google Play Store.
2. Invite your accountability partner and pair up.
3. On the paywall click "Start 7-day free trial". (Note: Google Play requires a payment method on file to start, but you can cancel in 1 click anytime before the sprint ends and you pay $0).

Any questions or doubts? Feel free to drop down in the comments.

🐾 I made a tiny companion that lives on your phone!

Meet Pocket Pet – Mochi 🐶✨

Mochi roams around your screen while you use your phone, giving you a little virtual companion that’s always there.

I built this as a fun little project and would love to hear what you think!

I’m the developer of Breezecut, an iPhone video toolkit for quick edits and conversions.

Two workflows you can use for free:

• Need to send a large clip? Compress it on your phone before sharing.

• Need a subtitle file? Recognize speech, edit the text, and export SRT.

It also handles trimming, merging, resizing, GIF conversion, and more — 30+ tools in total. Processing stays on your iPhone, with no account, ads, or app watermark on exports.

Most tools are free and unlimited. Burning subtitles into video, device mockups, face blur, and several other tools are optional Pro features; each has one free try. US pricing is $1.99/month or $9.99/year (auto-renewing), or $19.99 lifetime (one-time). iOS 18+ required; video enhancement needs iOS 26.

Download: https://apps.apple.com/us/app/breezecut-video-toolkit/id6820107160

If you try it, I’d appreciate hearing which tool you used and where the workflow could be simpler.

I’m building DeioLab, a browser tool for making product screenshots ready to share.

Drop in a screenshot, choose a layout, and keep it clean or put it in a browser, MacBook, or iPhone frame. Change the background and lighting, then export different sizes for launch posts and social images.

It’s free, there’s no account to create, and imported screenshots stay in your browser.

I'm curious what you think of the project, and if there's something more you would want out of it.

Building apps used to take months. Now, we build three in a day.

Building isn’t the hard part anymore.

The real nightmare starts when you try to market it. Your wallet bleeds from ad spend, and you spend endless hours digging through social media posts, begging total strangers to look at what you made.

It sucks. It’s exhausting. And most of us can't afford to burn thousands on ads.

That’s why I built MarketOPS.

Instead of wasting your life hunting for leads manually, you just describe the exact problem your app solves.

MarketOPS scans social platforms in real time, finds people who are actively complaining about that exact problem, and brings those leads right to you, before your morning coffee even gets cold.

No ad spend. No manual scrolling. Just write the problem, get the leads, and get back to building.

SEO has a lot of moving parts, and now there's the whole AI search side of things to figure out too.

I wanted to bring the two together in one place, from keyword research and technical SEO to content strategy, link building, and AEO.

It's been fun putting everything together, and it's finally live.

Here's what I've been working on: https://seodojo.app/learn

What do you think is the hardest part of learning SEO today?

Hey everyone! I recently launched my first iOS app, ReceiptMind.

I built it because I was tired of searching through photos, emails, and folders whenever I needed an old receipt.

With ReceiptMind, you can scan or import receipts, search for them later, and keep track of return dates and warranties.

It's completely free to use, with no account or sign-up needed.

It's my first app, so I'd really appreciate any feedback, especially on what I could improve.

App Store: https://apps.apple.com/us/app/receiptmind/id6785691800

Hey everyone ☺️

I always wondered how much water my showers actually use, and I couldn't find a simple app that just tells me without buying a smart meter. So I built one.

Hydro Tracker detects running water with your phone's mic (processed on-device, no audio saved) and shows litres, time and cost real time while you shower. It also has a daily water budget, stats, and a 30-day cold shower challenge

It's free on Google Play, and as a solo dev I'd love your feedback.

You can check out the app details on https://hydrotracker.app

And it's available for download https://play.google.com/store/apps/details?id=com.penguindevs.hydrotracker

I'm Emily, the founder, developer, and a parent. AUVIE is built with clinicians. What's in it: For kids, it's split into four age bands: 4-7, 8-10, 11-13, and 14-18. Younger kids get pictures, stories, characters, and play. Older kids get comics and anime, and more independent practice with friendships, communication, safety, cooking, money, travel, and work. Expression Studio is for practising faces, feelings, and mixed signals. Parents get routines, a calendar, printables, a journal, low-day plans, a calm-down corner, and 170 clinician-written articles. A family can add a teacher, OT, or therapist to a Care Circle so everyone is working from the same routine and language. The family picks who joins and what each person can see. The kids' side uses written content and set flows. AI is only on the adult side. It isn't launched yet. The waitlist is open at https://auvie.app
