Fitness Tracker Device Development

We need a device that captures raw accelerometer and gyroscope data, push/force sensor readings, real-time GPS accurate to cms, memory function, weight sensor, and user-taggable GPS locations. The device should have an LCD screen and buttons for user interaction.
We are open to make changes in order to curb the cost of the product like(removing lcd screen and controlling it via phone because we will be developing a mobile app as well)

Key Requirements:

Raw Accelerometer and Gyroscope Data
Push/Force Sensor Integration
Real-Time GPS Location Embed (Accurate to cms)
Memory Function
Weight Sensor
User-Taggable GPS Coordinates
LCD Screen with Buttons

Connectivity:

Real-time data transmission to mobile app via Bluetooth or Cloud

User/App Interaction:

LCD screen and buttons for user input.
Users can update information, reflecting in real-time on the app/cloud.

Let's build it!
