School Kids Location Tracker Mobile App

I need a mobile app for both iOS and Android that helps monitor school children's locations.

Key Features:
- Manual input of location and activity: This feature allows teachers or supervisors to record when a child goes to the toilet, plays outside, etc.

Ideal Skills and Experience:
- Cross-platform mobile app development
- Experience with location-based services
- UX/UI design for children-friendly interface
- Understanding of data privacy and security measures

Please provide examples of similar projects you've done in your proposal.
