Apple Watch App

Job ID: 32371489

Budget: $30 – $250 USD

I'm currently developing a React Native app and would like a watchOS app to accompany it.

What I'm looking for is someone to develop a watch app that can display :
1. a static title saying: stress assessment
2. a subtitle that can change depending on the selected time-interval
3. A-line graph with 2 lines, with the data format {x: string, y: number}
4. 2 static graph labels below the graph
5. A button to change the interval matching an enum [week, month, quarter, half-year]

a mockup can be seen in the uploaded file watch.png

Data retrieval:
currently, I'm unsure how the data retrieval would work so I can't provide any good instruction, but here is what considerations/options I have thought about.

option 1:
some kind of session (maybe WCsession) where the app saves the data, but since it's a React Native project I'm not sure how that would work.

option 2:
The data for one of the graphs can be retrieved from a server with a valid login and the other is just the HeartRate from HealthKit formatted to display average values matching the selected interval.
(HealthKit META data is also available in a local realm-DB made to improve performance over HK querying and formatting, though not sure if this data is available since the DB is on the phone).

option 3: anything else besides libraries that works

I can provide:
- typescript functions to create the string for the subtitle
- typescript functions that transform raw HealthKit data into the targeted intervals
- colour codes
- text strings

Looking forward to working with you and hearing how you would tackle the data retrieval
Best regards Alex
