Weekly Dev Update - New Algorithm

Feb 11, 2026

Version 1.4 has just been released. The update should be available very soon.

This is a significant backend upgrade for MOTRA. While there are meaningful performance improvements across the app, the main focus of V1.4 is the new Max Heart Rate algorithm.

A Smarter Max HR Model

We have rebuilt how MOTRA determines your Max Heart Rate and heart rate zones.

The new system can establish accurate zones with less historical data than the previous version. New users automatically sync 90 days of workout history on signup, and in testing, that dataset alone is typically enough to generate a reliable prediction — assuming there is a reasonable mix of training intensities.

This is critical. MOTRA rewards verified intensity, not just movement. If zone calibration is wrong, effort scoring is wrong. Improving this layer strengthens the entire reward system.

Performance Improvements

We have also made substantial performance upgrades behind the scenes. Workout processing is faster, and overall responsiveness has improved.

More optimisation work is already underway.

Thank you to everyone providing feedback. Every release moves us closer to setting a new standard for effort-based rewards.
