Minimalistic iOS Moisture Sensor App

I'm looking for a skilled iOS developer to create a minimalistic, user-friendly app for monitoring moisture levels via Arduino sensors. The app will connect with 1 to 8 sensors over Wi-Fi, displaying their readings on a grid layout.

Key Features:
- User can set a default moisture level
- Visual feedback: table turns red when moisture exceeds the set level, stays green when below
- Option to display readings from 1, 4, or all 8 sensors
- Push notifications alerting the user to changes in moisture levels

Ideal Skills and Experience:
- Proven experience in iOS app development
- Prior work with IoT (Internet of Things) applications is a plus
- Strong understanding of minimalistic design principles
- Experience implementing push notifications in apps
- Knowledge of creating grid layouts within an app
