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.

It would be 5 stars if only the call recordings weren't so terribly hard to sort. They are in day-month-year format, so every 1st is together, which is not at all handy when you're looking for "a call that happened in January". It also needs to have an obvious way to pause the damn thing, uninstalling it to make confidential calls that require the keypad, and then reinstalling it, is cumbersome. Edit this does nor appear to record calls anymore, which makes it less than useful.

I've tried a few different call recorder apps, and this is the only one that has worked for me so far. I can hear both sides of the conversation, especially if I put it on speaker phone. It hasn't stopped recording at random times or recorded silence. I like that I have the option to only record the calls I want, not all of them. UPDATE 3-29-23: App suddenly stopped recording any audio. It is now useless to me. Will have to uninstall. 😢
