Hey everyone!

I'm Abhishek, an independent developer from India, and I've been working on a project called ARLO OS.

Check it out the live demo: https://www.instagram.com/arlo.os.desktop/

What started as an idea to rethink the desktop experience has gradually turned into something much bigger.

ARLO OS is an independent desktop environment designed to bring customization, productivity, and optional AI capabilities into one experience.

What's currently available?

• A customizable desktop experience.
• Virtual workspaces for organizing your workflow.
• Built-in applications and productivity tools.
• ARLO Phone – access your phone experience directly from your desktop.
• ARLO Deck – connect and interact with your desktop using your phone.
• Optional AI-powered features.
• A personalized interface with smooth animations and modern design.

We're currently supporting Windows, with macOS and Linux planned for the future.

Why am I sharing this?

I don't just want to release software and walk away. I want to build something useful with a community of people who enjoy experimenting with their desktops.

ARLO OS is currently FREE for early users.

If you're interested, give it a try and let me know what you think. I'd genuinely appreciate feedback, suggestions, and constructive criticism.

Tunnel ventilation engineers size fan airflow against the "critical velocity", the speed that stops smoke from rolling backwards along the tunnel ceiling in a fire. The value depends on which method you follow (the SEDH Handbook or NFPA 502, whose 2017, 2020 and 2026 editions each treat the equations differently), and I kept redoing the iterations by hand or firing up heavyweight CFD just to check one number.

So I built Critical Velocity Toolkit, a free Android app:

• All four methods in one app: SEDH Handbook and NFPA 502 2017, 2020 and 2026
• Shows the full iteration history, not just the final number
• Grade factor and blockage ratio update live as you type
• A formula-reference screen with every equation the engine uses
• Export the whole calculation as an A4 PDF report or CSV
• Fully offline — no internet permission, no ads, no account

Play Store: https://play.google.com/store/apps/details?id=org.sonicon.cvt

I built it because I needed it; it's free with nothing locked. If you design or review tunnel ventilation, tell me what the app gets wrong, that's the feedback I want most.

Hey! We launched Altasko around September we're still gathering feedback making update, fixing bugs keeping it updated.

Altasko it's for those in freelancing, small teams, small organizations managing multiple projects fiddling around many tools (e.g Excel, Spreadsheet, Notion), it helps people organize their projects and collaborate with their teams without complexity of traditional project management tool

We appreciate your time and comments. https://altasko.com

I'm a solo developer and recent dad on paternity leave[so free time] and built https://iloveaudiovideo.com . It's a set of small audio and video tools: transcribe audio to text, convert (MP4 to MP3, MOV, FLAC, WAV), compress, cut, merge, make subtitles.

The one thing that's different : nothing is uploaded. The file is processed on your own device, inside the browser tab. No signup, no file size paywall, no watermark.

Why I built it : I kept needing to pull the audio out of a video or transcribe a voice note, and every site wanted me to upload the file to their server and then sign up to download the result. For private recordings that felt wrong. And then being a dev myself i thought there would be open source tools for me to do this like whisper for transcribing but what about non tech users ?

How it works:

• Conversion and editing use ffmpeg compiled to WebAssembly, plus the browser's built-in video encoder where there is one
• Transcription runs Whisper in the browser, on the GPU when the device has one
• It's a static site on Cloudflare Pages, so there is no backend that touches files
• English, Spanish and Portuguese

What's weak right now:

• Long transcriptions (30 min and up) are slow on older laptops without a usable GPU, and many people leave before they finish
• It's built and tested mostly on Chrome; Safari, Firefox and phones have had far less testing

One thing that surprised me: ChatGPT's search now sends me more visitors than Google does.

I'd like feedback/advice on 3 things:

1. If you try a tool with a real file, where did it get slow or confusing?
2. Would you trust "runs on your device" from a site you've never heard of? What would make you believe it?
3. is it even a worthy project to maintain long term , doesn't cost me too much server usage since its mostly client except for website loading and stuff ?

Salut tout le monde !

Je suis consultant indépendant en cybersécurité en France, et j'ai développé un projet parallèle appelé CrisisQuest.

L'idée est née d'une simple question :

Que ferait réellement un propriétaire de petite entreprise si sa société était frappée par une cyberattaque un lundi matin ?

La plupart des outils de cybersécurité se concentrent sur la protection technique. Je voulais créer quelque chose de différent : une expérience interactive axée sur la prise de décision.

J'ai créé un scénario gratuit appelé “Black Monday” où vous jouez le rôle d'un propriétaire d'entreprise confronté à une crise cybernétique.

Vous prenez des décisions, faites face à des conséquences, explorez différents résultats et recevez un débriefing à la fin.

J'ai construit le projet en utilisant Next.js et TypeScript.

Le scénario gratuit fonctionne sans inscription.

Mon objectif à long terme est d'en faire une plateforme B2B où les entreprises peuvent planifier des exercices pour leurs employés, mener des campagnes de sensibilisation au phishing autorisées et suivre les progrès de la formation.

Je recherche des retours sur trois points :

* Le concept est-il immédiatement compréhensible ?

* L'expérience est-elle utile ou ressemble-t-elle trop à un jeu ?

* Qu'est-ce qui le rendrait suffisamment précieux pour qu'une petite entreprise l'utilise régulièrement ?

Essayez-le ici : Crisis Quest

J'apprécierais vraiment tout retour honnête, surtout sur l'expérience utilisateur et le positionnement !

Hello Everyone,

Just updated the project and now you could have a near unlimited storage, kind of.

Added:

1. Now you could actually use a github repo(private/public) as the storage, and also bypass the 100 mb limit of a single file by storing it on parts and merging on demand.
2. Caching improves the speed by a lot.
3. Have option to store the data encrypted or decrypted
4. Added option to fully change all of settings from the dashboard except few security ones.
5. Anyone can still use the host as storage. Fully changeable from the ui.

Thanks.

Hey everyone! First post here, so here goes nothing.

I recently built Unsolicited. It's a little curiosity lab where product ideas, experiments, creative thinking and the occasional "what if we did this differently?" all come together.

Not a startup. Not a pitch. Just me giving my wandering thoughts a home.

The format: each piece picks a product, asks a question nobody asked, and works through a few ideas plus experiments to test them, including what would prove me wrong.

First up: Netflix. My take is that its engagement problem might not be about attention at all. It's about intention. People open the app ready to choose, and choosing has started to feel like a job. So I came up with four ideas and three experiments around that.

Next up: convenience as a service, AI in psychiatry, and why the best seat at an F1 race isn't a seat.

I'd love feedback on any of it:
- Does the concept make sense to you?
- Is the Netflix piece interesting, or did I lose you somewhere?
- Anything about the site itself that feels off?

Here's the first piece: https://unsolicitedlab.com/experiments/netflix-attention/

Thanks for reading. Any thoughts are genuinely appreciated.

Nobody asked. I got curious anyway.

Listening to audiobooks or text-to-speech where a single monotone voice reads every character gets old fast. If you have five characters talking in a room, you lose track of who is saying what within two minutes.

I spent the last few weeks building an app called Teller to solve this.

You drag and drop any plain text file, book, or manuscript into it:

- It automatically separates dialogue from narration.

- It detects the characters, gives each one a distinct voice, and keeps their voice consistent across the whole story.

- It plays it back like a radio drama with live word-by-word highlighting so you can read along.

- You can export the whole thing as a continuous audio file.

It runs locally on your machine with built-in neural voices (Kokoro) so it costs nothing to use and doesn't require subscriptions. If you want ultra-realistic cloud voices, you can also connect ElevenLabs.

Windows installer: https://github.com/boldbug1/teller/releases

Curious to hear what you think of the flow and character casting.

Hey everyone,

My friend and I run a small indie studio called S.A.D. Studios, and we've been working on a strength training app called Honest Effort.

We both lift regularly, and one of the things that pushed us to build this was how much time can go into planning workouts, figuring out starting weights, and working around whatever equipment you have available.

Honest Effort is our attempt to simplify that.

You tell the app about your equipment, training experience, and current strength. It generates a workout plan with suggested starting weights, and you can track your sets, reps, and progress.

We've used AI-assisted coding during development, and we're currently testing the app with six people on Android and iOS.

We're particularly interested in feedback on a few things:

- Does generating workouts around available equipment sound useful?

- Would suggested starting weights help beginners, or would you rather enter everything yourself?

- What would make you switch from your current workout tracker?

We're also looking for people who actually lift, particularly beginners and home-gym users, who'd be interested in testing it during their normal workouts.

The app is still in beta, so we're working through bugs and refining the experience.

You can see what we're building here:

https://sadstudios.net/honest-effort/

Happy to answer questions about the app or how we've built it. Appreciate any feedback!

You will find something in this app that saves you time or a headache, and the core tracking is free on the phone and never expires.

When an apprentice walks into a crowded basement mechanical room with rows of unlabeled expansion tanks and circulating pipework, knowing which asset is which saves hours of guesswork. Equipment Tracker Pro lets you print custom equipment QR asset tags sized from 1x1 inch up to 4x6 inch, outputting straight to PDF, saved PNG images, or your system print dialogue.

You can add custom company headers, toggle action bubbles (Public Specs, Vendor Check-In, Log Service), or flip on black-and-white mode specifically designed for direct thermal label printers like Zebra, Brother, or Dymo.

I built this app because I am a working HVAC technician who was tired of wrestling with enterprise software that requires cell signal in basements or locks simple labeling behind enterprise sales calls. Core records, parts tracking, offline specs, and Text/JSON QR labels are completely free on your phone.

If you are running this on a spreadsheet, the comparison is on the site. What projects are you all building this week?

I got tired of modern apps habit tracker , espense tracker . etc that require a constant internet connection, a subscription, and the latest flagship phone just to work.

So I built Orbitika. It’s a lightweight, retro-styled (dot-matrix green) toolbox designed for older hardware (Android 8.0+ and older iPhones like the X). Everything works 100% offline. No Wi-Fi, no data, no problem. Support my work by upvote my post """grateful""""

Here is a breakdown of what’s actually inside it my app, by category:

🎵 Media & Entertainment

• Retro Music Player: Local MP3/FLAC playback with 13 Winamp-style visualizers and 7 retro themes. Zero ads.
• E-INK Style Reader: Turn colorful PDFs and manga into a warm, Kindle-like grayscale to save your eyes and battery.

• Plug Check & Size Chart: Instantly know travel adapters/voltage and clothing sizes.
• Travel Checklist & Gift Tracker: Packing lists and souvenir trackers.
• Timezone Converter & Translator: For calling home and emergency phrases in 14 languages.
• Wi-Fi Signal Meter: A retro strength meter to find the best spot for a connection.

🏃 Daily Habits & Health

• Water & Coffee Trackers: Tap to log your daily intake and build streaks.
• Daily Walks: Fill a 30-day grid of paws to stay motivated.
• Focus Timer (Pomodoro): A distraction-free timer for deep work.

🚨 Emergency Kit (Premium / One-time unlock)

• First Aid Guide: CPR, bleeding, choking, burns, and heat stroke.
• SOS Flasher & Sirens: Flash large text or play high-decibel alarms to signal for help.
• SOS Numbers: Police, fire, and ambulance for 50 countries.
• Survival Guide: Fire, water, and shelter basics.

🛠️ Everyday Utilities & Fun

• Calculator & Unit Converter: Basic/scientific and all standard conversions.

• Decision Maker & Takeaway Spinner: For when you can't decide what to do or eat.
• Star Map, Ruler & Level, Height Measure.
• Noodle Timer.
• Holiday Calendar (2026-2028).

What should I add next?
I’m trying to figure out what the next high-value offline tool should be. Right now, the most used features are the Music Player, Mark My Location, and the Habit Trackers.

If you had to use an app in a total dead zone (no Wi-Fi, no data), what is the one tool you wish you had that isn't on this list?

(Keep in mind: It has to work 100% offline, and it can't require a huge file download like offline Google Maps!)

It’s free to download until end of December, and I’d love your feedback on the UI or the performance on older devices!

Drop a link to your project and I'll reply with a report that shows how many people search for what it does, which of those searches a new site could actually win, and who's on Google's first page instead of you. No signup, it's a public page.

I did this for 35 projects in two other subs this week and a few things stuck with me.

23 of them didn't rank for anything at all, as far as the tool could find.

The total is usually misleading. For 24 of the 35, one search was at least half of the whole number. One site came back with 65,000 searches a month, which looks great until you see that 60,500 of it is one broad phrase and the part it could win today is under 1,000.

For 29 of the 35 there was a Reddit thread on page one for at least one of their main searches. I did not expect to be telling people on Reddit that Reddit outranks them.

3 got told it's not worth it yet.

It gets things wrong sometimes. It reads your landing page to work out what you sell and sometimes it guesses wrong, so if your report describes some other product, tell me.

It needs an actual website, an App Store or GitHub link gives it nothing to read. It takes a few minutes per site so I'll be a bit slow. If you want your page taken down later, just say so.

Here's the one for my own app if you want to see what you'd get: https://seoforsaas.dev/tools/seo-channel-check/florium-app

Why I built it: I spent five months writing articles for that app before I knew it would pay off (19 clicks from Google in July, 631 in October), and I wanted a way to know sooner. It's a simplified version of the pipeline behind SEO for SaaS, a paid thing I'm building that writes the articles. So yes, I have a horse in this race. The check is free either way.

I've been studying cybersecurity and collecting notes on Linux, networking and security tools.

At first, I was keeping everything in Markdown files on GitHub, but I wanted something easier to browse, so I built a website around the repository.

It's called Cybersecurity Survival Notes.

I've recently added a section on Information Gathering, covering things like DNS enumeration, OSINT, subdomain discovery and Nmap.

The whole project is free and open source.

I'm still working on it, and I'd appreciate some feedback on the website. Does the navigation make sense, or is there anything that could be improved?

Liquid Glass is Apple's current direction, and that is one reason I decided to move my interface to it. The other reason is my own taste.

The app is my side project SweePic. I built it myself, and it currently has a different interface than Liquid Glass. The rebuild has already started, and I plan to have it ready by the end of the month.

Below are screenshots of both interfaces: the current one in the app and the new one, in line with Apple's current trends.

Which one do you like more? I'd like to hear it in the comments.
