Cold Shower
Hello there, I'm working on an android app that allows to easily track the time and temperature of your cold showers and ice baths. Main features include the possibility to visualize your progress over time, achievements when you reach new time and temperature limits, a “badass score” that makes it easy to compare your progress with others, and a Voice Coach that keeps you motivated and makes you feel less alone in the cold. I’d appreciate any feedback on the app. More specifically, I would like to know how intuitive the user interface is, and what UI changes would make it a better app.…

- IMI made a privacy friendly and simple app to track my menstruation2024 · play.google.com · ▲732
Hey HN, after the app I actually used to track my period wanted me to log in and save my data in the cloud, I decided to write my own. Most apps in this area are based on a subscription model and display far too much information anyway. For me, a simple calendar is enough where I can add a few notes if necessary. So that is the result of my work - a simple design and the data is only saved on the smartphone.
Workout.cool – Open-source fitness coaching platform2025 · github.com · ▲827I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
