Beatlap: HIIT Interval Timer

Beatlap is an interval timer that keeps you on the beat.

Build a workout from sets and phases — work, rest, warm-up and cool-down — then start it and follow the big countdown ring. Each phase can have its own step-rate metronome, so your running cadence or lifting tempo stays steady from the first set to the last.

★ WHAT MAKES IT DIFFERENT
• Built-in metronome per phase: click, woodblock or drums, at any beats per minute
• Spoken phase names (“Run”, “Rest”…) using your phone's text-to-speech
• Cues play over your music — Beatlap never pauses your playlist
• Drift-free timing: cues and beats are scheduled on the audio stream itself
• Keeps running in the background and on the lock screen, with pause / skip / end in the notification and headset buttons

★ BUILD ANY WORKOUT
• Any number of sets and phases, with warm-up and cool-down
• Intensity curves: ramp work and rest across sets — linear, fast-then-slow, slow-then-fast, S-curve, steps, pyramid or alternating
• A long break every N sets
• A wide range of sports with their own icons: run, sprint, walk, cycle, row, swim, jumping jacks, boxing, strength, core, stretch, hike, stairs and more
• Tune volume, beat and durations while you train — changes are saved to the workout

★ READY-MADE EXAMPLES
Run intervals with building rest, Tabata, stretching and a bench-press tempo set — or quick-start any sets × work / rest in one tap.

★ TRACK YOUR TRAINING
A weekly strip, a monthly calendar coloured by sport, total time and your streak.

★ MAKE IT YOURS
Several themes (Aurora, Night run, Mono, Sand, Paper, Tonal) and many interface languages.
