Didn't give 5 because it is not working with bluetooth (using jabra talk 2). No other way other than buying an android watch to see who's calling. Otherwise its fine. We need it most with headset on and while carrying the phone in the pocket or driving. A little bit low on voice but working fine. Please fix the problem ASAP.

Waited for this app to be available from Backtracking Technology for few months. But it is not their fault, Google will not approve the app for some technical reasons. During the wait "Backtracking" kept me updated and given me the assurance for the progress. Customer service is second to none, always answered emails within 48 hours. From the day one, I know this is the app for me, as I have tried all others I know most others don't work with Android 9 or 10. This app is beautifully designed, before you try anything else, try this one first. Just installed on my phone, so far so good, will post if anything else changes. Well done Backtracking team and keep up with the good work. Even I am happy to pay for a paid version.
