Review summary

ThermaSesh is praised for its simplicity, reliable logs, and heart-rate tracking during sauna sessions. Users appreciate a lightweight, focused design that does what they need. The standout feature is heart-rate monitoring with session logs. However, recurring stability issues—errors and crash messages after workouts, with occasional data not saved—limit its reliability. Overall it delivers straightforward sauna tracking, but feedback emphasizes improving stability and adding integrations (e.g., Strava/Health).

Pros

Simple and easy-to-use interface.
Reliable tracking and logs of sauna sessions.
Heart rate monitoring capability.
Lightweight, focused app that fulfills core sauna-tracking needs.

Cons

Frequent errors/crashes and error messages after sessions, with data sometimes not saved.

2026-03-05	Te*****	I LOVE this app but it’s broken now. I have an error every time I use it, doesn’t measure heart rate and when I end session it throws error and doesn’t save

2025-03-11	Sk*****	What does inarticulate mean? The app is super simple and free. Works well enough for my purposes. But I don’t understand why the starting time of a session is out of sync with my iPhone by a few seconds. Shouldn’t it pick up the iPhone time whenever I create a new session?
