User Reviews

Overall, users like Apple Watch integration, temperature tracking, and the app’s ease of use and responsive updates. Recurrent concerns involve unreliable heart-rate capture, occasional timer glitches, stability issues, offline-start limitations, and occasional Strava data-sync quirks.

Pros

Strong Apple Watch integration and reliable session logging (including Strava uploads).
Accurate water temperature readings.
Intuitive, easy-to-use interface with timers, guided breathing, and notifications.
Comprehensive tracking for cold plunge and sauna (time, temperature, heart rate).
Highly responsive developer and frequent updates.

Cons

Heart rate tracking is unreliable or not syncing with the watch.
Timer behavior can be unreliable or inconsistent (disappears, continues after time, variable vibrate).
App can crash or feel unstable at times.
Offline usage limitations (can't start activities or load products without internet).
Occasional data sync issues (e.g., Strava timing discrepancies).

Recent reviews

Works good for the first few days - then very inconsistent. I have ultra 3 for reference. It seems like every other day the app believes I’m getting into a 44° sauna and then the other half the time the app just continually loads for a minute at a time. Not auto ending the cold plunge session when you leave the plunge also is very frustrating. It seems like it’s better just to use the free dive app that comes with the watch.

What works well: The app loads and connects with Apple Watch fine. It records the session and uploads to Strava. It logs your sessions. What doesn’t work well or at all: It doesn’t seem to know my location even though it has location permission. It logs the session at the correct time but uploads it to Strava with a time 10 hours later. There is no online support, just a static website. Update to my initial review (one month later): the developer has responded to every issue I had and the app is functioning much more consistently now.
