This document discusses the development of an unofficial mobile application called HeartCheck that monitors a user's heart rate using a Xiaomi Mi Band to help prevent heart disease. It outlines personas, touchpoints, and features for the app. It also describes challenges in using the Mi Band SDK and proposes using the open-source Gadgetbridge app as an alternative. The development roadmap includes implementing Gadgetbridge functionality, researching algorithms, and contributing Google Fit synchronization to Gadgetbridge. Useful links are provided.

HeartCheck Unofficial App
[Team: Mauro Papa & Maria Palma ]

2. The Idea : HeartCheck [UPDATED]
Develop an unofficial application (called
HeartCheck) that is able to prevent an
heart disease by constantly monitoring the
user heart rate.

4. Ux Evaluation: Personas
PERSONAS: Selected users representative of a specific population group.
FIRST GROUP:
Avg users
SECOND GROUP:
Users with
heart diseases
THIRD GROUP:
Doctors

5. Ux Evaluation: Touchpoints
TOUCHPOINTS: Steps users need to move from “need” to “end goal”, and
how users interact with your product. In UX maps touchpoints are table columns.

9. Xiaomi Mi Band SDK: A nightmare
The available unofficial SDKs released for Xiaomi Mi Band are not updated
anymore and are not compatible with latest band firmwares.
POSSIBLE SOLUTION:
Gadgetbridge: Open source app to replace wristbands vendors' closed source
Android applications. Supports Pebble, Mi Band, Liveview, HPlus etc.
CONs:
• It isn’t an SDK but an open source app
• It doesn’t feature Google Fit for now
PROs:
• Still updated
• Support for Mi Band 2
