About this APK
IsTalk - chat analysis is an app by REALBIND in the Entertainment category. It includes native code only for ARM 32-bit, so it won't run on 64-bit-only phones such as recent Pixels.
It asks for 22 permissions, 3 of them sensitive: precise location, read shared storage and modify shared storage. The app offers in-app purchases through Google Play and can read the advertising ID that ad and analytics services use.
