Heft: Workout & Gym Log
Lift log, rest timer & PRs
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Heft is a fast workout log for the gym. Open it at the rack, log a set in a tap, let the rest timer run, and walk out with every number saved.
LOG A SET IN A TAP
• Big, thumb-friendly weight and rep controls
• 430 exercises with animated illustrations, the muscles they work, and the equipment they need
• Warmup, working and drop sets
• Your last session sits right there, so you know what to beat
• Add your own exercises, with your own photo and notes
REST, ON THE CLOCK
• The rest timer starts itself when you finish a set
• Set a default for compounds and another for isolation, or override it per exercise
• It keeps running when you leave the app, and tells you when rest is up
• Plate math shows what to load on each side of the bar
EVERY PR, CAUGHT
• Records flash as you lift: estimated 1RM, heaviest set, most reps, best session volume, longest hold, furthest distance, fastest pace
• Per-exercise history and estimated 1RM trend charts
• A weekly streak built on days trained against a target you set
MORE THAN BARBELLS
• 46 activities, from runs and rides to boxing, tennis, yoga and climbing
• An interval timer with Tabata, EMOM, AMRAP and rounds you build yourself
• Skills sessions for 14 disciplines, including parkour, gymnastics, calisthenics, climbing, skateboarding, BMX, surf, ski and snowboard, logged as attempts and landings
APPLE HEALTH
• Save your workouts and your weight to Health
• Bring in runs and rides from Apple Watch and other apps, matched so nothing is counted twice
• Read your sleep, so it sits beside your training
• You choose what it reads and what it writes
TRAIN WITHOUT YOUR PHONE
• Focus mode holds back every app except the ones you allow while a workout runs
• Bedtime blocking does the same between lights out and wake, whether or not Heft is open
• Both use Apple's Screen Time on your own device, and both are free
ALSO INSIDE
• Home Screen and Lock Screen widgets, and a Live Activity for the rest timer and the running clock
• Progress photos and clips of your sets, kept on your device and never uploaded
• Reminders for your training days, and a wind-down the night before
WORKS WITH YOUR ASSISTANT
Connect Heft to an AI assistant that speaks MCP, then say "log bench 3x8 at 80 kg" or ask how your week went. Entirely optional.
