Looks good

So far so good.

The design needs some fine tuning but the app functions well. Calibrates my power meter and shows current values. Don't need much else!

Fantastic app and technology from 4iiii Innovations!

I can finally pass through all the data from my ANT+ sensors via BLE to my phone! Quite a nice app interface as well.


Works perfectly with my Sportiiiis and VIIIIVA!

This is a great way to set up my 4iiii stuff. It's much better than using a laptop because I can set it up anywhere!
