I’ve tried a few monitoring apps over the years for different reasons, and honestly? Most of the free ones are complete garbage. They promise you’ll see everything - texts, calls, location - but then they barely work, crash constantly, or drain the battery so obviously that anyone would notice.
The “free” ones I downloaded were either loaded with ads or wanted payment after like 2 days. Such a waste of time. Why is it so hard to find something that actually does what it says? Even the paid ones I tried had sync issues half the time.
