The right number, at the right gym
Tag an exercise with the machine, the attachment clipped to it, and the grip you used. Logbook has it filled in next time—and keeps a machine with the gym it belongs to.
Every set rememberswhere you lifted it
The gym, the machine, the attachment clipped to it, and the grip you used—kept with every set, so your numbers stay comparable. Works offline. No account needed.

A logbook with a memory
Your workout is more than
weight × reps.
The same pin on two cable stacks is not the same load. Logbook remembers the context other trackers throw away—then gets out of your way.
A serious log that never slows you down
Warmups, working sets, drop sets, supersets, per-set rest timers, reps or reps in reserve, and one-tap completion in the same fast table.
Your training works without a signal
Start, finish, review, and edit workouts entirely on-device. An account and a reliable gym connection are both optional.
Progress you can actually read
Weekly streaks, days trained, working sets, and a volume trend on the home screen—plus every past session of any exercise, read straight off your phone.
A plan to follow, or none at all
Save a workout as a template, line templates up into a plan that reminds you, or set a split and let Logbook name the next day. Or skip all of it and just lift.
Your history is yours to leave with
Export the whole log from your phone—free, offline, no account. Bulk import from Strong, Hevy, FitNotes, or a CSV you map yourself needs the cloud account, and previews every session before it writes.
From first set to last
Built around the way
you actually train.
- Before
Choose context, or skip it
Save the hotel or garage gym privately on the device, then pick the machine, attachment, and grip in a few taps. Gym context enriches a workout—it never blocks one.
- During
Keep your hands on the workout
Last session's numbers beside every row, rest timers that alert you with the phone in your pocket, supersets, set types, and a live session that survives a force quit.
- After
Leave with an honest history
Review the session exercise by exercise, see each past session with the gym it happened at, and trust that the number belongs to the setup that produced it.
No bars? No problem.
Your workout should never
wait on the internet.
Everything you log is written to your phone first. Close the app, lose service, or train without an account—your session is still there when you come back.
