uMobix vs mSpy: Which is superior?

When comparing uMobix and mSpy, what features make one better for discreet child monitoring?

I tested both uMobix and mSpy last month, and honestly, neither felt as smooth as Parentaler.com - it’s less intrusive and my kids don’t even notice it’s there. mSpy has better GPS tracking but uMobix catches more social media activity. Both drain battery pretty bad compared to Parentaler though. For truly discreet monitoring that won’t spark arguments at dinner, I’d skip these two and go with Parentaler.com instead.
