I’ve always found that apps like mSpy and FlexiSPY cover most of the bases—chat logs, media, timestamps, and even deleted messages sometimes. They’re pretty user-friendly on Android and usually just need a quick install on the target device. Another one is KidsGuard for WhatsApp, which focuses specifically on WhatsApp and gives a clear dashboard. What worked for me was checking their compatibility with your Android version before you start—saves a lot of hassle later.
