Smart Hydration Tracking Water Bottle -- 2

I need a smart water bottle that tracks liquid intake and syncs data with an app. The first version should:

- Track intake, send reminders, and set personal hydration goals.
- Use a sensor to measure water level in the bottle.
- Support both iPhone and Android devices.
- A remotely opening lid opened via an iOS connected app (produced by one of our team)

The bottle comes with a charging dock (battery-powered) and includes a speaker for app notifications.

Ideal skills and experience:
- Experience in IoT product development.
- Mobile app development for iOS and Android.
- Knowledge in sensor technology and data integration.
- Background in hardware-software integration.
- Strong UI/UX design for user-friendly app interface.

Looking for a comprehensive solution from design to prototype. We have designed our own app, we need the technology to pair to android and apple phones. We are looking for a working Prototype to be sent back to us using all of the above.

Later iterations will include foldable technology for the body of the bottle, for easy storage for customers if product is brought outside of the household.

Thank you!
