This is a big project. We need an app developing which will read data from multiple fitness bands (F1, wearfit, DayDay band etc.) and enable us to persist this into the cloud as well as presenting the data nicely like the FitBit app does. It must be written with React Native and have a .NET core backend (I'm not too fussed on what datastore is used but it HAS to beable to take a huge amount of write data - think couchbase, traditional RDBMS might be ok at first but will surely suffer at scale with the amount of data being written over time).
The app must be a premuim quality app, think UBER rather than the low quality of the existing dayday and wearfit apps. It must also work on tablet and support multiple devices being connected.
Please get in touch with any questions!
