At the top where is currently says "Boil Timer" change to "Brew Timer - [MODE]" were [MODE] would be "Boil Mode" or "Mash Mode".
When on click "New Profile" ask which mode desired, then "Enter Profile Name"....
Bottom Menu, move "Preferences" to the "More" menu and replace with "Mode Type" to allow current timer to be changed modes in a pop-up. This would probably need some sort of alert that "Timers will be reset if mode is changed"
Just my thoughts. Thanks for your work
