Hi everyone! 👋 I'm Masayuki, a solo iOS developer from Japan.
I built meiso because I wanted a meditation timer that goes beyond a simple stopwatch and actually shows whether my practice is working.
How meiso quantifies meditation:
• Apple Watch (or any Bluetooth heart-rate sensor like Polar H10) records your heart rate
• A custom FFT pipeline computes HRV (LF/HF ratio) from R-R intervals
• You get a "meditation skill level" — think of it as Strava for mindfulness
Why it might help:
• Beginners can finally see if they're "doing it right"
• Long-time meditators can track progress over months
• 100% free, no ads, no subscription, no sign-up — all data stays on-device / Apple Health
