Heave is a strength training timer and workout log designed to run gym sessions on autopilot. Instead of acting as a static digital notebook, Heave paces your reps with audio chimes, handles rest intervals automatically, and makes set logging fast and frictionless.

You structure your workouts once—defining exercises, target reps, rep tempos, and rest durations. During a session, Heave guides the timing of every set and transition so you can focus on lifting without constantly checking your screen or managing stopwatches.

CORE CAPABILITIES:

CHIME-PACED REPS & AUDIO TIMERS
• Audio chimes sound on every rep tempo, keeping your time-under-tension consistent.
• Start-of-set, end-of-set, and rest countdown cues let you train by sound with your phone set aside.
• Wakelock keeps the display awake throughout the workout so current targets remain visible.

QUICK-STEP WEIGHT & SET LOGGING
• Adjust load on the fly using fast stepper controls without typing on a keyboard between sets.
• Target reps and previous weights load automatically for the upcoming set.
• Log completed sets in one tap to instantly trigger the next phase.

AUTOMATED REST COUNTDOWNS
• Rest timers start automatically the moment a set is marked complete.
• Independent rest durations per exercise (e.g., longer rest for heavy compounds, shorter for accessory work).
• An alert chime signals when your rest window ends and your next set begins.
