Good business model but very basic
The app works my cheap Megane heart rate monitor and I appreciate that it’s just one price, no paying with your data or monthly subscription or nonsense like that. The app is VERY basic though. You have like five workout categories and you can’t edit them afterwards or add your own. Yoga isn’t one of the categories. I sometimes do a sitting-to-standing baseline test and I have to count it as a workout lol. So I’m not sure I’d recommend.
