Cross-Platform Phone Location Tracker App

I'm urgently looking for a skilled app developer who can create a cross-platform phone location tracker app. The app should support both Android and iOS devices. Here are the core features I need in the app:
- **Real-time Tracking**: The app should be able to provide real-time tracking of the phone's location.
- **Location History**: It should also be capable of storing and displaying the location history of the phone.
- **Geofencing Alerts**: I'd like the app to have geofencing alerts, so it can notify me when the phone enters or leaves specific predefined zones.

I'm in a rush to have this project completed, so I'd like someone who can commit to delivering this as soon as possible.

Ideal skills and experience for this job include:
- Proficiency in both Android and iOS app development
- Experience in creating location-based apps
- Familiarity with real-time tracking and geofencing technologies
- Ability to work under tight deadlines.
