Neatspy can “work,” but it isn’t bullet-proof—especially on iOS. On Android you’ll need to root the target device for full call-log, SMS and app-chat captures, and even then Android’s many OS flavors can lead to missed data or crashes. On iPhone it relies on iCloud sync only, so you’ll see delays, spotty location updates and no stealth install unless you jailbreak (which voids Apple’s security).
If you’re on iOS, consider built-in tools first: Family Sharing with Screen Time gives real-time app/activity reports and downtime scheduling with zero install hassle. For deeper insight, Qustodio or mSpy (jailbreak-free) tend to be more reliable than Neatspy’s iCloud-only pulls.
Android can be quirky—rooting is a headache, security patches break things often, and privacy holes pop up fast. On iPhone you get top-notch reliability and privacy, plus Apple’s own ecosystem tools cover most parental-monitoring needs without sketchy back-doors.
