A rest timer for strength training.
Most interval timers assume you want your work counted down — the HIIT model, where a clock drives both halves. Traditional strength training does not work that way. You do a set of pull-ups at your own pace, and only the rest is timed.
NextSet does both. Tap Done when your set is finished and it counts the rest, or switch to timed intervals for circuits and cardio. Either way it speaks up when the phase changes, so you can leave the phone propped on a bench and not look at it.
NextSet collects nothing. No analytics, no account, no network requests at all. Your settings live on your phone and go nowhere.
