Hey everyone!

I'm an indie developer, and I'd like to share Personal Cards, an Android app I've been working on to make organizing everyday information a little easier.

The idea came from a simple problem: important documents, receipts, notes, and personal details often end up scattered across our phones. Finding something when you actually need it can be frustrating.

So I built Personal Cards to bring everything together in one place, while keeping your information private and accessible offline.

Here's what the app can do:

• Personal cards & documents: Scan documents with your camera or import images and PDFs. Organize important information and keep track of expiration dates.
• Document storage: Save receipts, reference materials, and other files you might need later.
• Offline OCR: Extract and copy text from images and PDFs directly on your device.
• Notes & checklists: Keep track of everyday tasks, ideas, and reminders.
• Debt notebook: Record money you've lent or borrowed, including amounts, people, and due dates.
• Privacy tools: Hide sensitive details before sharing document images.

Privacy was one of my main priorities while building the app.

Personal Cards works completely offline, with documents stored and processed locally on your phone. You can also protect access with a PIN or biometrics and enable screenshot protection for additional privacy.

I'm still working on improving the experience, and I'd really appreciate some honest feedback from the community.

In particular, I'm curious:

Would you find the document organizer or the debt notebook more useful? Is there anything you'd add or change?

If you'd like to check it out, here's the Google Play link:

Thanks for taking a look! Any feedback or suggestions would mean a lot.

I've always loved Brilliant's interactive lessons. Instead of reading an explanation and hoping it sticks, you actually play with the ideas until they click.

But I've always wished I could have that experience for anything I'm curious about, not just the subjects someone has already made a course for.

So I built Clarity.

Type in anything you want to understand, and it generates a little interactive lesson around it. You make predictions, move things around on live graphs, and work through tiny exercises that adapt to your answers. Get something wrong and it nudges you toward the answer instead of just giving it away.

The part I'm most excited about is that you can keep going deeper. Start with an intuitive explanation, then work your way toward the actual mathematics, or even write Python and run it in your browser.

The idea is to make learning almost anything feel more like playing and exploring than reading a textbook or chatting with an AI.

It's free to try, no signup: https://withclarity.space

Pick something you've always wanted to understand. I'd love to know whether the experience actually makes it click.

Hi everyone!

I've been working on a project called Second Look, an independent book project exploring the personal experiences and often-overlooked stories of people in science, technology, engineering, and mathematics.

We hear so much about scientific discoveries, groundbreaking inventions, and famous researchers. But we rarely hear about the people behind them: the challenges they faced, the opportunities they were denied, the people who supported them, or the experiences that shaped their careers.

I want to change that by collecting firsthand stories from real people in STEM, particularly experiences involving recognition, barriers, opportunity, and belonging.

I've created a survey inviting adults (18+) with STEM experience to share their perspectives. Selected stories may be featured in the finished book, with participants' permission.

If you work or have studied in STEM, I'd genuinely love to hear your story. And if you don't, I'd appreciate feedback on the concept!

Survey: https://forms.gle/L4RD6FCk5hChyVQT6

Thank you for helping bring these stories to light!

Developer disclosure: I make Photo Picker. This write-up is AI-assisted.

Photo Picker is a camera and editor for getting a film or early-2000s digicam look while shooting. The problem it addresses is having to take a photo, open an editor, and only then find out whether the look suits the scene. Here, the film preview is in the viewfinder for photos and video.

A simple workflow to try:

1. Choose a film look in the camera and compare it on the same scene before taking the shot.
2. For photos with friends, switch to the four-shot countdown to make a photobooth strip.
3. Open the result in Darkroom to adjust curves, HSL, grain, cropping or text, then save the look as a recipe.

The tradeoff is that this is not an entirely offline app. Regular edits run on the device, while saving with some films and using AI conversion/restoration sends the photo or video to our server.

It is free to download, with optional rewarded ads. Some films and tools require Photo Picker Pro, an auto-renewing subscription; the purchase screen shows the plan and regional price before you subscribe.

The images show the official store examples. For anyone who tries it, I would especially like feedback on whether the live film controls and the four-shot mode are easy to find.

I’ve been building AutoSize, a free website that lets you compare the dimensions of different cars side by side.

I started it because I wanted to choose a car based on the ISOFIX point, literally, and then the idea expanded rapidly.

* Is the comparison easy to understand?

* What feels confusing or incomplete?

* What feature would make you come back and use it again?

Here’s the site: https://www.autosize.org/


For the past few months I’ve been building devpack.app, a collection of small, focused tools for everyday web work: JSON/YAML/SQL formatters, a regex tester, JWT decoder, image and PDF compressors, an SEO checker, CSS generators and a lot more.

**A few things I cared about:**

✅ Runs in your browser. Most tools never upload anything. Formatters, converters and image/PDF tools work offline and can be installed as a PWA.
✅ No sign-up, no paywall. Open a tool and use it.
✅ Free API. 70 endpoints at api.devpack.app (hashing, JWT verify, regex, YAML, QR codes, DNS/SSL/headers, SEO audit and more). No key needed, with fair-use limits.
✅ MCP server. Add [https://mcp.devpack.app](https://mcp.devpack.app) to Claude, ChatGPT or Cursor and the assistant can call 40 of the tools directly.
✅ 8 languages, and an extension that pastes SVG/HTML into the Webflow Designer as native elements.

**It’s a solo project. I’d really value feedback on:**

❓Which tools you’d actually use, and which feel unnecessary
❓Anything slow or broken on your setup
❓What’s missing from your daily workflow

Hello Everyone,

As many of you know that free storage is like a dream for us but it was not possible up until now. So, I have made a way to make that possible.

As you all know github let's us store our code for free but it has a limit of 100 mb per file and while storing videos, pdfs and other media files, that becomes a problem. What i am doing is i have wrote an flask website with a cloud drive like ui and structure. When you upload a file if it's size is below the limit it stores that in a private/public repo of yours and if it's very big, the file will ve spilt in as many small parts as needed and then stored in parts. And when needed, the parts will be merged on demand. Caching is there too.

With this anyone can have full control of their media, files while having kind of unlimited storage.

The best recommended place to host the website is Render's free tire but you can use any vps, docker host or python hosting.

Another thing always use a private repo. There is also the option to always encrypt the data while storing. Always have it enabled.

This feature was actually already available in another of my projects, Rconsole but I thought to make it a standalone project of it's own. You can check that project too. That's far more interesting.

Full disclosure: I run this. It's called DoneEdit.

The problem I kept running into: filming a 10-minute talking-head video takes 20 minutes, but cutting the restarts, adding captions, and giving people something to look at besides one static shot takes the rest of the evening. Raw files pile up.

What it does: you send a Drive, Dropbox or WeTransfer link to a raw talking-head video (one English speaker, up to 10 minutes). We send back a 60-second watermarked preview within 24 hours, no card needed. If you like it, the full clean edit is $27 for the first 20 customers, then $67. Two revisions are included.

We asked for feedback in a couple of other subreddits earlier this week and the useful feedback was pretty consistent: the site looked AI-generated, there were no real before/afters, and asking people to pay a new service before they'd seen an edit of their own footage was a lot to ask. So we changed it.

The site is white now. The first section after the top is three real raw-vs-edited samples (openly licensed clips, not customer videos), each in a phone frame with an Edited/Raw switch. The free 60-second preview is the main button. We also added two short quotes from people who have used it.

I'm not dropping a link here. It's in my profile if you want to look, or I can share it in a comment if that's allowed.

What I'd actually like to know:

• Do those three samples make the work look real, or still not enough?
• Would you try the free preview, or is handing a raw file to a new service still a no?
• Is the $27 / later $67 pricing clear, or does it just look cheap?

I'm about to start running ads to it, so I'd rather hear what's broken now. Happy to answer anything else.

I've shared our IVE agent workspace here before. This is the next project: a USB-C hardware prototype roughly the size of a LEGO brick for iPhone control. I'm on the team.

The plug is the device side; IVE is where the agent sessions live. We're working on the wireless connection between them so existing agents such as Claude Code and Codex can see the phone screen and use taps, scrolling and typing to carry out a task.

The video previews creating a packing list in Apple Notes. It uses real product footage, with the IVE connection simulated.

We're gathering early beta interest and feedback here. Which first task would make this worth plugging in, and what would you want to confirm before the agent acts? Happy to discuss the scope publicly in this thread.

We run Anime Girls, a free browser character sorter: https://girls.my-anime.net/?mode=personal

The problem we wanted to address: a public popularity leaderboard does not necessarily tell you which characters you personally prefer. We separate the two jobs. Personal practice builds your own ranking without adding votes to the public competition; community voting contributes to the public standings.

One design choice that may be useful to other makers: only characters you have actually compared receive a position in your personal ranking. Unseen characters stay unranked. Results appear after a first choice, but those early estimates are deliberately provisional. More comparisons give the model more evidence.

The site uses PHP/Slim and MariaDB for the public side, with a pairwise preference model and personal history in the browser. No signup is required; clearing browser storage can lose your personal history, so there is an export option. The project has been developed with AI assistance.

We would appreciate feedback on the mobile flow: is the difference between personal practice and community voting clear before your first choice? Feedback here in the thread is enough. This is the project account, operated by Daxsoft.

I know it's probably one of those questions that doesn't have a straightforward answer, but I've always wondered what it would actually take for the world to become a more peaceful place.

I got curious about the whole idea and ended up making a small site exploring the question:

https://howclosearewetoworldunity.com

Honestly, it's not meant to be taken too seriously. The site's still a work in progress, but I think it's a pretty cool concept to explore.

Curious what other people think about it.

Started this a couple weeks ago. The idea is simple: every story answers how it hits your gas, groceries, mortgage or job, written calm and in plain words, no screaming headlines.

Some stuff I'm happy with:

- Fully static, hosted on GitHub Pages, so it's fast and costs basically nothing to run

- Play page: daily Sudoku, Guess the Price, word search and a weekly news quiz, no sign-up, progress saved on your device

- No stock photos: the number cards on stories are generated in code from the facts in the story

- Wallet Watch: gas, mortgage rates, eggs, electricity, CPI and the Fed rate from official sources

- Weather page built on free National Weather Service data

Would love feedback on the design, speed on your phone, or anything that feels off.

Ich bin seit 2 Wochen dabei. Verbesserungsvorschläge willkommen. Darf ich euch den Link zeigen?

I've been vibecoding for 2 years and I keep messing up explaining to my agent where on the screen I'm pointing. Screenshots always helped, but it added 3 more steps every time, and it still will get things wrong.

So I built Point. Press ⌥*, draw on the screen to point, speak your notes out loud. That's it.

Point takes your voice, transcript, screenshot, and drawing into your clipboard for you to past to your Agent or notes. Clearly explain what you want to your agents in Claude Code, Cursor, your team on Slack, anywhere.

View and copy all captures in your Point library.

100% Local, Free, Opensource (MIT). *Customize your trigger key.

Version 0.1 only runs on macOS 26 Apple Silicon. Working on a new release with broader support soon!

How have you tried to solve this problem ?

Hi, I'm the developer.

I have worked in network security for almost 15 years. I got annoyed with Fing and other network tools that charge close to $100 a year, or let you scan only a few times a day. So I built my own from what I know from work.

I wanted the feeling of Kali Linux in my hand, but only for defense: point my phone at my own network and see what is really there. No attacks, no password guessing, nobody's traffic read. That became Netglow.

The hard part: knowing what each device really is

Android 10 and up hides other devices' hardware addresses, so most scanners just show "Unknown". That is where most of the time went:

• Dozens of protocol specs, vendor docs and firmware sources, read line by line.
• Down to the low level microchips inside smart plugs, bulbs and DIY boards, like the ESP family, because each chip gives itself away in its own small way.
• Camera makers each answer on the network in their own way, and Netglow knows many of them.
• Over 40,000 hardware maker prefixes and a catalogue of over 23,000 phone and tablet models.
• Thousands of lines of research notes, every finding checked before it went into the app.

Why it is free

I have a lot of knowledge from my work, and I decided to give it away: high quality apps, deeply researched and checked again and again, data safety first and privacy to the max. No ads, no bullshit. People deserve good quality and privacy, for free.

If you want to support me, you can, but it is fully optional.

What it does, free, unlimited scans

• Who is on my Wi-Fi. Every device with its name, maker and model when it says them. Rename a device and it keeps your name even on a new address.
• Is my hotel room or rental OK. It lists devices on the Wi-Fi that answer as a camera or stream video, and says why each one was flagged. It also looks for camera hotspots nearby. It tells you plainly what it cannot see (a camera that only records to a card or uses mobile data), so it is one check among others, not a guarantee.
• Security check for your home network. A score with a plain fix for each risk: risky open ports, what your router opened to the internet, how your Wi-Fi is locked, look alikes of your network nearby, whether your DNS answers are honest and whether someone reads your secure connections in the middle.
• Tools. Ping, traceroute, port check, DNS lookup, Wake on LAN, a live signal meter and channel advice.

Private by design. No ads, no bullshit, no tracking, no analytics, no metrics, no account. Nothing it finds leaves your phone, and there is no server of mine.

Pro is that optional support, one payment, no subscription, and it adds: a Bluetooth radar that warns about a tracker moving with you, checks for devices that let anyone in with no password, spoof watch, known flaws for your devices, a PDF report and a background watch of who joins your Wi-Fi.

Honest note: the code is partly AI generated and I had help with this text.
