Weekly Dev Update — Heart Rate Max Algorithm

This week was a really important step forward. Getting max heart rate right.

We’ve built and shipped the new Max HR algorithm into MOTRA. The app now analyses every workout you complete and adjusts your max heart rate over time based on how your body actually responds to effort.

This is a big shift for the platform. It means effort becomes genuinely personal.

When your max heart rate is accurate, your zones are accurate. When your zones are accurate, your Effort Points reflect real work. It was key to get this right, as any manual override of the max heart rate left the system open to be exploited.

We also pushed the alpha to the full team this week. Everyone’s now hands-on, logging sessions, and trying to break things. Early signs are strong, but we’re collecting everything and tightening up the experience.

Beta testers are next. If you want in, join the waitlist.
