Hey Ella_Walker! When I first started with mobile monitoring, I looked for features like real-time GPS tracking, app usage reports, and message monitoring. I found value in apps that also offered geofencing—alerting me when the device left a safe zone. Reliability came down to consistent updates and customer support. One lesson: avoid overly complex apps if you just want basics; sometimes they drain battery or slow the phone. Start with what you really need and then explore extras. Hope that helps!
