u/SWISS_KISS

Hi everyone - I am working as a software engineer for over 15 years - I built Spargel, an app (iOS+Android) that compares grocery prices across Migros, Coop, Denner, Aldi, Lidl and Ottos. It normalises prices by kg, litre or unit and can work out the cheapest way to buy your shopping list across one, two or three stores.

My original monetisation idea was simple: offer a limited number of searches, then charge for more.

But the more I thought about it, the more backwards it felt. The people who benefit most from comparing every franc are often the same people who don’t have spare money for another subscription. So now the app is 100% free.

So I’m rethinking the model and would genuinely value your opinion: How would you monetise something like this without defeating its purpose? Optional supporter plan? Affiliate links? Clearly labelled sponsored deals? Something else? B2B? Why would Migros/Coop/Aldi/Lidl... pay me for this?

And just as importantly: what kind of monetisation would make you immediately uninstall it?

Here’s the app if you’d like to see what I mean:

Hey! I’ve been building SecondWeb/Web3D.World or the Metaverse?!

You drag one bookmarklet into your browser, open any website, and click it. The page becomes a low-poly multiplayer city: DOM elements become landmarks, every URL is its own P2P room, and players can walk, drive and use spatial voice chat.

The idea is to turn the internet from pages we consume into places where people meet and make every website a game level waiting to be explored and conquered.

It’s still an early prototype, but you can try it here:
https://swissmade.xyz/secondweb/ - don't forget to put you on the list to get notified when it's finished, so you are the first one collecting items on the most famous websites!

Desktop Chrome is recommended for now. I’d love honest feedback on performance, installation and what would make you come back. Theoretically it should work on any websites, but a lot of websites block CORS - so if you think the idea is nice I could also create a chrome extension so it would work on any website!

Should I invest more time into it? Btw my first startup was MetaRoom.city - something similar; but more "polished" and not a game.

I've been building BilindGo, a free app for learning Kurdish, and I'd really like this community's feedback on it.

The idea it's built around: most apps pick one dialect and ignore the rest. So the core of the app is a wheel. You take one sentence and spin it through pronouns, tenses and dialects, and you hear each version spoken out loud. Watching "I am going" turn into Kurmancî, Soranî, Zazakî, Lorî and Goranî (Feylî and more coming) side by side shows how close they actually are, instead of treating them as separate worlds.

What's in it:

• All five dialects: Kurmancî, Soranî, Zazakî, Lorî, Goranî (Hewramî)
• A live AI voice tutor you can actually talk to. You speak Kurdish out loud, it answers back in your dialect in real time. Useful if you have no native speaker around.
• Vocabulary, verb conjugation tables and an alphabet trainer, all with audio
• Small games: a 3D village where quests are Kurdish commands, a taxi ride for directions and numbers, a market run for food words, quizzes and XP
• No account, no ads, the core lessons work offline

It's free. Full honesty on the one limit: the live AI tutor costs me real money per minute, so there are free minutes every month and an optional subscription if you want longer sessions. Everything else (words, verbs, alphabet, games, audio) is free with no cap.

Try it in the browser without installing anything: www.LearnKurdish.app
iOS: apps.apple.com/app/bilindgo/id6789517319
Android: play.google.com/store/apps/details?id=xyz.swissmade.LearnKurdi

We are improving the app dayli and you can always report a bug or mistake over the red button on top right corner in the app. Together we will bring all Kurds closer to eachother and we will learn that our languages are not that different once we had some exposure on eachothers words.

Spas 🙏

With the current situation of the strait of hormuz and the possible risk that europe could run out of oil and fertilizer, I created an app for the day after tomorrow.

Survive is an Android app where every feature works with no connection:

• An AI assistant that runs entirely on the phone (Qwen2.5 1.5B, one-time 1.6 GB download). Airplane mode, mid-blackout, doesn't matter.
• An ultrasonic messenger: sends short text messages phone-to-phone through sound. No internet, no bluetooth, no pairing. Speaker to microphone.
• Morse/SOS flashlight signaling, offline map packs, field guides rewritten from the public-domain US Army survival manual, emergency numbers per country, and a panic mode that walks you through triage questions.
• Zero tracking. No analytics SDK, no ads, no account. I genuinely cannot see what anyone does in the app.

That last point is also my problem: I shipped in March, did zero marketing, and it sits at ~15 downloads. This month I fixed my biggest onboarding failure (the AI model download was effectively broken for real users and I didn't notice for weeks, because, well, no telemetry) and rewrote the store listing.

Honest feedback wanted on the listing: https://play.google.com/store/apps/details?id=com.survive.app&utm_source=reddit&utm_campaign=sideproject

Does it make you want to install, and if not, at which line do you stop reading?

I just started learning a bit about the robotics topic. I created a simple quadruped dummy robot in fusion 360 with correct naming convention for nvidia isaac lab and trained the robot to teach itself "walking" and stay stablized on 4 legs. If anyone is interested aI wrote my findings in a blog here: https://zaniyar.github.io/robotic/ maybe it helps someone who is interested but does not know where to start..

My next steps are building the So-Arm 101 which I ordered (forget to order the 3d printed parts.. now ordered a X2D 3d printer to print them myself).

Since one of our students is creating a opensource quadruped robot; I am very curious how the trained model will be transfered on the jetson computer in the real world.. let's see.

It took me quiet a while to make this somehow work; it's still not perfect and slow; but it's for free, so why not try it.

For now it's available on Android; in 2 Weeks on iOS
