Field Employee Tracking App Needed

I need a mobile application for both iOS and Android platforms to track field employees. The app should include the following features:

- Live location tracking of employees.
- Task management capabilities.
- A system for employees to check in and out.

While I do not require an admin panel, the app should have a user-friendly interface for easy management of the mentioned features. Ideal skills include experience in mobile app development on both platforms and expertise in implementing location-based services.
