We want you to help us develop a new product that will help our customers take daily PPG readings from their mobile device.

Goals:

A photoplethysmogram (PPG) is an optically obtained plethysmogram that can be used to detect blood volume changes in the microvascular bed of tissue.

- Using flutter code base. A simple mobile application should be written to take PPG readings.

- The PPG readings should be stored in a postgres database.

- The reading should last for a little over 1 minute.

- Calculations for HRV (SDNN, RMSSD, MaxMin) should all be calculated and presented to the user.

- During the reading time a live heart beat feed should be presented to the user. (BPM)

- During the reading if the user is moving too much (the PPG is struggling to detect blood volume changes) the user should be informed to remain still or restart the reading.

- During the calculations a quality of reading should be given to the user based on the data collected and ability to calculate their HRV. (Banding of quality can be decided).

- History of previous readings should be stored so the user can access.

- Historic readings should be charted.

We hope this new product will increase revenue and grow our customer lifetime value.

Technical Requirements:

- Must be written in Flutter

Design Requirements:

- Whilst we have a series of goals. The style, method & approach is how you see fit.
