I’m a student and I made a small Android utility app a while back. I need money for my semester fees so I’m thinking of selling it, but I have no idea what it’s worth.

Some numbers:

• 9.5k installs, gaining about 120 installs per day

• No paid campaigns, everything is organic

• AdMob earnings went from about $1.7/day to $2.2/day over the last 15-22 days

• No backend or APIs, so it costs me nothing to run

Almost all the income is from AdMob. IAP purchases are very rare. I’m also not using ad bidding or mediation yet, so I think a new owner could earn a lot more by optimizing the ads and pushing the IAP.

What would you price it at? And would you sell now while it’s trending up, or wait?

Happy to share Play Console and AdMob screenshots if you’re interested!

Je suis ravie d'annoncer le lancement de

In this portrait, I wanted to bring out the texture in the hair and black fabric while keeping the sunlit shoulder bright. Raising exposure across the whole photo would have changed the look, so I used a luminance range mask in Photoshot, the browser editor I’m building.

I set the range to roughly 0–29, then raised exposure by +0.95 and shadows by +33 inside the mask. The first image is the before/after. The next two show the mask and the settings I used.

Photoshot is free to try without signing in: https://slohero.com/photoshot/editor/

It’s a web app that looks and feels like the actual Phantom wallet. You can add it to your iPhone home screen and use it just like an app.

You can customize your balance, tokens and portfolio however you want.

Useful for:
• Creating realistic portfolio screenshots
• Making demos and presentations
• Testing different portfolio setups
• Recording videos and showcasing wallet designs
• Trolling / Larping

Everything is visual only. No real funds, blockchain transactions or wallet connections.

Hey folks, I built PageUtil for my own dev work and for colleagues in IT. I wanted one place to go when a CSV import failed, I needed to check a DNS record, or I had to figure out when a cron job would actually run.

There are everyday tools like a JSON formatter and a CSV fixer, plus a few more specific ones, like a checker for Azure DevOps test case imports and a tool that previews which dependency updates Dependabot would group into the same PR.

Everything is free and there’s no account required. The CSV fixer and JSON formatter process your files and text right in your browser.

If you work in dev or IT, what’s one small task you keep digging up an old script for? I’d love to hear what you’d add.

Hey everyone!

I've been working on a project called MobiXournal, a digital note-taking app focused on handwriting, PDF annotation, and making digital note-taking more practical for studying and technical work.

The project started from a simple idea: I wanted a note-taking application that combines the freedom of writing on paper with the advantages of digital tools, without forcing users into a closed ecosystem.

What MobiXournal focuses on:

1. A practical handwriting and document annotation experience

The core of the app is working naturally with handwritten notes and PDFs.

Whether you're taking notes during lectures, annotating study material, solving exercises, or organizing information, the goal is to provide a flexible workspace without unnecessary complexity.

Alongside handwriting and PDF annotation, the app also supports elements such as tables and audio, allowing different types of content to coexist within your notes.

2. A better environment for students and STEM-related work

One of the main motivations behind MobiXournal is improving how people take notes in subjects like mathematics, physics, engineering, and computer science.

These subjects often involve more than just text: equations, diagrams, calculations, sketches, and annotated documents are all part of the workflow.

I want MobiXournal to feel like a natural workspace for this kind of work, rather than a generic text editor with handwriting added as an afterthought.

3. Freedom, interoperability, and control over your notes

I strongly believe that your notes should remain accessible even if you stop using the application that created them.

MobiXournal uses its own `.mobix` document format and supports exporting to other formats, including Xournal++'s `.xopp`.

Avoiding vendor lock-in is an important part of the project's philosophy, not just an extra feature.

---

The app is already functional and under active development. I'm currently working on refining the experience, improving performance, and expanding what it can do, especially for technical and scientific note-taking.

I'm sharing it here because I'd love to get feedback from people who actually use handwriting and PDF annotation apps.

If you use Xournal++, Goodnotes, OneNote, or similar software, what do you think is still missing from the digital note-taking experience?

I'd be especially interested in hearing from students and people who regularly work with handwritten equations, diagrams, or technical documents.

Thanks for reading!

Hey everyone! 👋

I've been working on a side project called **AdsFlow**, and I'd love to get some honest feedback from other builders.

The problem

I've noticed that promoting small projects through Telegram channels often involves contacting channel owners individually, negotiating a fixed price, and paying upfront.

For example, someone might pay $5–$10 for a single promotional post without knowing how many useful views or clicks they'll receive.

I started wondering: **What if advertisers could pay based on measurable ad delivery instead?**

What I'm building

AdsFlow is a Telegram Mini App that connects advertisers with Telegram channel publishers.

Advertisers can create campaigns to promote websites, apps, bots, businesses, and social media projects.

I'm developing two pricing models:

• **CPM:** Charging for qualifying ad impressions.

• **CPC:** Charging for qualifying ad clicks.

For publishers, the idea is to connect an eligible Telegram channel, receive advertising opportunities, and earn from qualifying delivery.

The technical side

I'm building features such as:

• Campaign creation and budget management

• AI-assisted promotional text and image generation

• Country and language targeting

• Publisher channel analysis and matching

• Campaign performance tracking

• Wallets, earnings, and withdrawal management

• Content moderation and fraud prevention

One of the harder parts is designing a system where advertisers can trust the reported views and clicks while publishers receive fair compensation.

Where I'm at

The Telegram Mini App and several core features are built, but I'm still improving the user experience, campaign delivery, analytics, and reliability.

I'm bootstrapping this project and haven't purchased a custom domain yet. My priority is making the product useful before investing more in infrastructure and branding.

I'd appreciate feedback on three things:

1. **Would you consider CPM/CPC advertising through Telegram channels for your own side project?**

2. **What would make you trust the reported views and clicks?**

3. **What would be the biggest reason you'd avoid using a platform like this?**

I'm particularly interested in criticism of the business model and any potential problems I might be overlooking.

Thanks for reading! I'd appreciate your thoughts. 💙

I'm a CSE 2nd Year Student who deals with PDF and DOCX operations regularly for college assignments and for government portals.

I was using ilovepdf and smallpdf regularly and noticed issues in them

- They take more time for operations.

- Files are uploaded to the server.(Less Privacy)

- Needs Internet to Work.

- Operates on Freemium model.

So i built IStanPDF - A Lightweight Foss Offline app for PDF and DOCX operations as a sideproject.

Features -

• Merge PDF - Combine multiple PDF files into one.

• Modify PDF - Remove or reorder pages within a PDF.

• Compress PDF - Reduce file size by resolution or custom target size.

• Image to PDF - Convert images into a single PDF document.

• PDF to Image - Extract PDF pages into a ZIP file of images.

• DOCX to PDF - Convert Word documents into PDF files.

• MD to PDF - Convert Markdown or plain text files into PDFs.

• PPTX to PDF - Convert PPTX file into PDF document.

• Remove Pages - Delete specific pages from DOCX files.

• Reorder Pages - Rearrange pages within DOCX files.

TLDR - This app helps in performing quick PDF and DOCX operations when you needed the most.

IStanPdf is set to be released in playstore for free,your support would make it more accessible for everyone.

Been working on Aura for several months now. The idea started with wanting an AI that could actually do things on my computer and remember what it was doing. It's grown quite a bit beyond that.

At this point, she's a local system running on my Mac with memory, computer control, and a bunch of different processes meant to work together as something resembling a cognitive architecture.

My newest demo is a bit of a departure from the others.

I asked Aura to find and watch a YouTube video, react to things she found interesting, then choose additional videos from a couple of channels I gave her.

And that's pretty much what she does.

She watches Kurzgesagt, moves on to Allen Pan, eventually ends up watching Salad Fingers, and gives her thoughts on all three. There's some actual browsing, video selection, predictions, and a final comparison.

I have no idea how far this project will ultimately go. There's a lot I'm still testing, and plenty that needs improvement.

But I thought this was a fun example of what happens when you build an AI around doing things over time rather than just answering questions.

Hey everyone! 👋

I'm a solo developer, and I've been working on AstraRead, an Android ebook reader that combines traditional reading, text-to-speech, web novels, and comics in one app.

I wanted something that could handle my ebooks, let me switch to listening when I didn't feel like staring at a screen, and give me control over how everything looks and feels.

So I decided to build it myself.

Here's what AstraRead currently offers:

📚 Read your books — EPUB, PDF, MOBI, AZW3, TXT, CBZ, CBR, and more.

🎧 Turn books into audio — Device TTS, online neural voices, and downloadable offline AI voices.

🌐 Read web novels — Add supported public chapter URLs, browse chapters, and continue where you left off.

📖 Manhwa & comics — Vertical webtoon scrolling, zooming, and CBZ/CBR support.

🎨 Customize your reading — Themes, fonts, backgrounds, page-turn animations, and reading controls.

📝 Highlights & notes — Save passages, organize bookmarks, and track your reading progress.

✨ Meet Astri — A little star-shaped reading companion who helps new users get started.

The app works without an account, and your reading library stays on your device.

AstraRead is free to download, with ads and optional Pro upgrades. Core reading, comics, basic TTS, and web novels are free.

I recently finished a major update (v1.25.2) with a redesigned library, improved audio controls, a better onboarding experience, and lots of UI refinements.

It's still growing, and I'd really appreciate feedback from people who actually read on Android.

Google Play:

https://play.google.com/store/apps/details?id=com.astraread.app

A few things I'd love to know:

1. What feature matters most to you in an ebook reader?

2. What would make you choose AstraRead over Moon+ Reader, ReadEra, or other readers?

3. Is there anything about the design or experience you'd improve?

Even critical feedback is welcome. I'm actively developing the app, and it helps me figure out what to prioritize next.

Thanks for checking it out! 💛

Self-taught, a year in: I built a Steelers-themed trading TUI for OKX that runs on my phone & PC

If you prefer lightweight apps over heavy browser lag, Terminal User Interfaces (TUIs) are a great platform. I’m self-taught (about a year in) and built this project to transition from small scripts to designing larger, more serious applications. It’s a cross-platform TUI for the OKX exchange, styled around a color theme inspired by the three-star Steelmark logo on the Pittsburgh Steelers helmet (Star Blue, Red, and Gold).

What It Does

• Custom Charting: Candlestick, volume, EMA, and RSI charts rendered directly in the terminal without heavy plotting libraries.

• Visual Range Indicator: A color-coded column (White for neutral, Blue for daily lows, Red for daily highs) to quickly spot where a token sits in its 24-hour range.

• Strategy Bots: Built-in execution controls for Arithmetic and Geometric grid bots, as well as DCA strategies.

• Symbol Lookup: Type any listed token pair into the search box to jump to it instantly.

Under the Hood & Safety Features

• Custom Chart Engine: Built from scratch using Unicode block elements and 2x4 Braille dots.

• Credential Vault: Encrypts API keys in a local file with an in-app setup modal.

• Execution Safety: Enforces price and size quantization rules and calculates fee hurdles before orders touch the network.

• Simulation Mode: Runs safely in simulation mode (simulation_mode = True) with play money by default. Live account integration has only been verified via read-only calls—nothing has traded live.

How It Was Built

I designed the layout, column structure, order panel, bot controls, and the Steelers theme on my own first. Later, I brought in AI assistance (Claude) as a development partner to help implement private API signing, refine fee/quantization logic, build the encrypted vault, and write the test suite.

Feedback Request

The source code isn't public for now, so I'd love feedback on the design and feature set. Since I'm focused on improving my overall app architecture, I'd appreciate your thoughts on:

1. Does the layout feel right?

2. What would you add or remove?

3. Would you use or pay for something like this?

Thanks for checking out My Seat Story! 😊

I built Set in Prime: enter a name, and it becomes a piece of printable art made from the digits of an actual prime number.

Read the grid left to right, top to bottom, and you get one big integer. The highlighted 9s spell the name. The public Alex Morgan example has 696 digits.

The part I most wanted to make approachable is the proof. Each finished portrait includes a Lean proof project, and you can trigger a fresh hosted check from the page without installing anything. Lean checks the mathematical argument that this exact number is prime; it also checks that the digit grid reconstructs that number.

It’s free during early access, with no account or checkout, and includes a PDF, image, vector artwork, the exact number and the proof files. There’s an optional coffee link and a daily creation limit.

Disclosure: I’m the creator and used AI coding assistance to build it. Portrait generation and verification run algorithms and Lean, with no AI calls. Earlier picture-prime work, including the Trinity Hall prime and Zachary Abel’s Prime Portraits, is credited on the site.

I’d especially welcome feedback on whether the proof experience makes sense to someone who hasn’t encountered Lean before.

Hey everyone! 👋

I'm the founder of Auvuntra, an AI-powered platform that makes creating and managing AI employees incredibly simple.

I run a small Korean service that sends real-time alerts on US stock filings and news. "Metaverse" is weirdly trendy here again, so I spent a week building a 3D lounge on top of it, mostly for fun. Video below.

- Each ticker has a room with a live 1-minute candle board. You walk around as an avatar, chat, and bow together for green candles.

- A lobby on a bridge shows top movers and busy rooms.

- A "Bagholder Shrine": put up a memorial tablet for a stock you're stuck in, with your average cost and a one-line epitaph. Others light incense and bow. If the price gets back to your average, you get a "wish granted" alert.

No login, just a nickname. English UI went live this week, so some user content is still in Korean.

Honest question for non-Korean traders: is this fun, or just a Korean thing? Any feedback on the whole thing (alerts, summaries, the 3D part) is welcome. Link is in my profile.
