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
