Keep some local data stored on the device (local cache)
Currently if you don’t have a data connection (i.e. patchy mobile data and no access to Wifi) you don’t get to see any data even historic data in the app. It relies on being online. It would be great if the app kept some of your historic data locally so that at least you can see your last few days analysis. A simple “Pull to refresh” action would allow the data to be updated if the connection wasn’t good enough to fetch the latest data when starting the app.
