## Review summary

Heartool provides real-time heart-rate data, zone percentages, calories, and a visual chart, with HIIT-friendly alerts and workout history, and it works well with Coospo HR monitors. Users praise its simple, accurate interface and usefulness for basic HR tracking. However, many reviews flag recurring network errors and login problems that break tracking and data saving; zone data can be incomplete or miscalculated (missing time-in-zone, inconsistent percentages); and there are occasional data accuracy issues compared with other apps and devices. Overall, core features are solid when functioning, but reliability and data accuracy need improvement.

- Real-time BPM display, heart rate zones (percentages), calories burned, and a live color-coded chart with zone alerts.
- Keeps a workout history with analysis options and max heart rate warning.
- Simple, accurate, and useful interface suitable for HIIT and basic HR tracking.

### Cons

- Frequent network errors and login issues that prevent tracking and data saving.
- Zone data display issues: missing time-in-zone data and inconsistent percentage calculations.
- Data accuracy concerns: readings may not match other devices/apps and calories are overestimated.
