The gravity scale on the fermentation tracker view is way too wide for it to be useful. It goes from 2.0 down to 0.0 which means my fermentation from 1.048 to 1.040 (so far) just shows up as a straight line.
There is absolutely no reason to have the scale go up to 2. Even an extremely high alcohol beer is unlikely to go much higher than 1.2. The same with the lower end, 0.0 doesn’t make any sense at all. A dry wine might go down to 0.990 and no beer is likely to go below 1.0, even Brut IPAs.
Of course even better would be to be able to adjust the scale yourelf to something sensible for the beer that you are fermenting.

I have the same problem with the WEB app, the Android app works better(1.072 - 0,96).
Thanks for the feedback @S P.
This is a clone of #17 and so I have merged it in with that one.
