I would rate higher if the app actually worked. Unfortunately it seems to have constant issues when it comes to syncing with devices. I tried all the recommended fixes, nothing works. Unsitalled and reinstalled, Turned of Bluetooth, restarted my phone, turned off the device itself... nothing works! Even if anything did work... it would not be worth it as I would just have to repeat the process over and over again. I miss out on lots of features because of this faulty app. Very disappointing.
