Loopwell is an interval timer that tells you what to do next, so you can stop watching the clock and get on with the work. Pick a preset or build your own: work, rest, rounds, warm up, cool down. Press start and Loopwell takes over — a big countdown you can read across the room, a distinct tone for every kind of step, and each step announced out loud. Put the phone face down. The cues keep going with the screen off. BUILD ANY INTERVAL PATTERN • Steps of any length, in any order, named however you like • Repeat the whole set up to 99 rounds, with optional rest between rounds • Get-ready countdown, warm up and cool down around the main set • Six presets to start from: Tabata, HIIT 40/20, EMOM, Focus 25/5, Run/Walk and a stretch flow • Duplicate any preset and reshape it into your own WHILE IT RUNS • One enormous countdown, colour-coded by step type • A progress ring for the current step and time left in the whole session • "Up next" so you always know what is coming • Pause, resume, skip forward, restart the step • Spoken step names and round numbers, plus a tick for the last three seconds • Cues duck your music instead of stopping it AFTERWARDS • Every finished session is logged with how long you actually spent • Sessions stopped early are recorded honestly, not rounded up • Weekly totals and a day streak MADE FOR ANY KIND OF INTERVAL Circuit training and Tabata. Running and walking. Stretching and mobility. Focus blocks and study sprints. Anything that repeats on a clock. PRIVACY BY DESIGN Loopwell has no sign-up, no login and no cloud.
