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.

Works great except when I'm on Bluetooth at work. There's too much background noise to hear the recording. But I'm not sure if that's really anything that could be fixed. I have recommended this app to a couple of women already!! Thank you! *Update* App no longer records any calls even after checking settings and making sure it was set to automatically record all calls. It's now completely useless to me.

So far, so good. Recordings are clear, memory management is nice, no spam, easy user interface, and at thos point, no problems. Good Update 9/14/22 - I've had several recordings that were really important that didn't seem to work and I can't get ahold of anybody for assistance. There's literally no customer service or contact option on the app that actually works, and there's no indication of how we're supposed to request help. Their FAQs are woefully limited in scope. Frustrating

The app works pretty well and records every call that I receive. However, when taking a phone call through the earpiece, the audio on the collars and does not sound very clear and is very dim or quiet. Best way to go around this is to put the call on speakerphone. Unfortunately, if you're trying to have a private conversation, you cannot. Hence my three stars.

This app records BOTH sides of the conversation. Yes, you can actually hear the other person when you replay the recording. I gave it 4 stars because while it does what it is supposed to do, record a CONVERSATION, I am unable to find instructions on how to save/store the recording. As for the ads, the only ad I saw was for a solitaire game. It was a bit annoying but, it closed and went away easily enough.

Sounds good so far. Nice interface and the extras are great for a free app! Calls are recorded clearly and on both ends. I haven't used the call blocker or the ID yet, but I like everything so far. It's nice to see an app full of extras instead of the bare minimum with tons of ads. It's simple enough to use as your default caller as well, unlike most that are too difficult to want to switch over. Good job!
