Get stronger without guessing. Spend less time logging than lifting.
Grin&Gain is a workout tracker built for lifters who want to make consistent strength progress without spending forever logging workouts.
Most fitness apps make you dig through menus, type endlessly, and guess how much weight to use next. Grin&Gain solves both problems.
