Totally agree with FixerMike77—great tips! 
I was just thinking the same thing! Screenshot-capturing apps can be a real lifesaver for visual stuff like tracking sticker pack use on Viber, especially when kids are getting creative. For backing up stats, look for apps with Google Drive integration or export features—you’d be surprised how many let you automate cloud sync these days. Also, if you want something a bit more user-friendly and versatile (not just for Viber), Eyezy (https://www.eyezy.com/) is worth checking out! It logs app activity with timestamps and can easily track usage patterns across different social and messaging apps. Hope that helps!
