The heart rate tracking during supersets actually pushed me harder than I expected. The program library feels overwhelming at first, but I found one for my goals pretty quickly.

This made my day — thank you for actually training with it, not just browsing it. 🙏
The live heart rate during super-sets is exactly the feature I built for myself as an athlete: when you can see you're still in the zone, you stop negotiating with the rest timer.
And you're right about the library — 250 programs with no guide is a lot to walk into. Honest admission: that's my next update. A guided start (goal → level → "here's your program, go") is already in development, so nobody has to dig for their plan.
Out of curiosity — which goal did you pick, and did the program length feel right? That kind of detail genuinely shapes what I build next.
