Set Swap started because logging a workout was the slowest part of doing one. Notes apps forget your numbers, spreadsheets need two hands, and the rest timer always lives in some other app.

So Set Swap does the boring parts for you. Templates carry your exercises across sessions, completing a set starts the rest countdown by itself, and reopening a workout prefills the reps and weights you actually hit last time.

Sharing is next. The name is not an accident: the best exercises come from the people you train with, and they should not get lost in a message thread. For now Set Swap is a logger, and we would rather ship that well than promise the rest early.
