The Dilution and Boil Off tools should be added under the Tools options.
These are 'must have' options.
I know this thing is a work in progress but I'm shocked they were not included.
If I were writing this software these would have been the first two tools.
The ability to log my brew day as I was brewing (update measured SG, pre boil vol, etc) and sync it with the desktop version was the one reason I bought this app.. Guess I should have done my research better. Please add it in the near future
