Interactive Cleaning Schedule App

I need an iOS app to manage a commercial washroom cleaning schedule and track supplies. The app should include:

- Interactive cleaning schedule
- Supply and usage tracking
- Notification alerts
visible information on a tablet of the last time the facility was serviced and the next time it will be serviced
It should have a 'call' button to alert the requirement of immediate attention if required.

Ideal Skills and Experience:
- Proficiency in iOS app development
- Experience with interactive scheduling tools
- Background in inventory tracking systems
- Strong UI/UX design skills to ensure user-friendly experience

Please provide relevant portfolio and experience.
