I installed this to record calls. It has lots of other features. I wish it could have done the one thing that's important to me. Record calls. But although it kicks in when a call starts, the file recorded is always blank. Support was initially prompt in responding with suggested settings adjustments that could resolve. But nothing changed and I heard nothing back. Such a shame.

When it works its great. When I first installed the app it added a record dot to the screen for calls incoming and out going. But that has disappeared so I can't record calls I receive. I've tried setting it to record all calls. But that didn't make any difference. I would like to continue with the app because when it works its great but if I can't record calls I'll have to look elsewhere.

UPDATE: Call Recorder doesn't work. Only records one side of the call - yours. Unfortunately, call recorders no longer work; none of them. The call blocking is not as good as I need. So many spoofed numbers were slipping by. Had to replace. ORIGINAL: Only had it installed for a few hours and it's asking for a review. So I don't know. Haven't received any calls yet. Might want to adjust the program to wait until the user has actually used the app before requesting a review.
