I use "callu" I believe it's called.
I'd give it a 3.5 out of 5.
- It only really records well if you use your speaker.
- it doesn't record at all your car's Bluetooth.
- it does back up to your Google drive, which is great.
- it always records whether you like it or not, which is a serious pain in the ass. I had an app before which would prompt you at the end of the call if you wanted to save the call, which was way better.
- it has both a paid and a free version. I'm using the free version and so there are ads, which are a pain in the ass.
All callers are recorded as "private", which makes finding that one call really difficult.
I like it because it works. The last app I tried was constantly not working. This is a BIG problem with these apps.
Maybe the paid version is better, I dunno. I need to do some more research.
