It's good so far. The UI is not Android style and has a retro theme look which I'm not a fan of but it's functional.
Works great with ANT+ and has great features, however the voice feedback is unreliable... Would also like to see other activities listed, such as skiing.
For the developer, I can't email/share to Google drive. Otherwise liked it so much I bought it. Useful monitor, clear, customisable - sometimes quick to connect to BLE HRM sometimes slower, but hasn't failed. UPDATE - a few glitches had one email from the developer saying "sorry he hadn't responded" and that's all still waiting for a response! Downgrade to 3 stars
Exactly what I need basic HR + calories nothing fancy works w/my schochi HR monitor easy to read on phone during workout
Gives a good graph at the end. Calories burned a tad optimistic, but you get the picture.
