CyberNanny helps parents look after their child's safety: where they are right now, what they do on their phone and whether they spend too much time on it. What you see on the parent's phone: • Your child's location on the map and where they have been today • Safe zones: home, school, clubs • Screen time and which apps your child uses • Which websites they open • Notifications about important events What you can manage: • Set time limits for apps and games • Block unwanted apps • Set a schedule for school, sleep and free time How to start: 1. Install CyberNanny on your phone and sign in as a parent. 2. Install the app on your child's phone and connect it with a QR code. 3. Manage everything from your phone.

Verdict
The clearest difference is update cadence: DeffApp at every 10 days against CyberNanny's every 3 weeks. DeffApp also leads on iOS requirement (15.6 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
