Comments on Call Recorder - callX for Android

★★★★☆ P Schindler · Feb 19, 2026

The program works well although, periodically it fails to record. I've then removed some of the calls, and it's back to recording. The sound was a problem at first; I had to try all the available settings. Premium edition still shows a static Ad below the weather forecast at the end of every call.

★★★★☆ Christian Nunley · Nov 11, 2025

I've used several programs like this & so far this is one of the best I've used. 4* because of the loud intrusive ads! It is getting better over time! Sometimes it just doesn't record the conversations. If it improves, I will give it 5*.

★★★★★ Shakir Bhat · Feb 16, 2026

Veey good app only issue is not all calls are recorded

★★★★★ Daniel Montalvo · Jul 17, 2025

I have this app since 2019 it's the best app it's safe me 1000s on fraud also ete this app is most have. It will be nice if it has the sound beep during the calls sound every minute like the Government still I give 10 stars 🌟

★☆☆☆☆ Raven Grey · Feb 17, 2026

Records silence lol also when I tried to find it to review it saved in my phone as #callex do take me a long time to find it again but was worth it to let everyone know, do not under any circumstances really on this application. It could cost you a legal battle.

★☆☆☆☆ DanielB · Mar 14, 2026

Any app that doesn't work (doesn't record or totally distorts other side of conversation), takes over my phone with an ad, and launches play store to install when I tap the X. . . Is malware GARBAGE. So, of course, I removed it.

★☆☆☆☆ Neal Jackie Daddy · Jan 20, 2026

An App that took a wrong turn some time ago and has now driven off a cliff. I've had this app since early 2014 and have thousands of calls saved. Sound quality was always an issue, but, what WASN'T an issue...was that this app always recorded when it should, always both side recording, and always showed the phone number of the recording, placement ads only (no video), and very simple UI. The app I have just described no longer exists. All those "pros" have evaporated. The app is useless now. Junk

★☆☆☆☆ Iron Tongue · May 14, 2025

Could not hear the caller in the recording. Could you hear myself? Could not hear the caller.
