Watch yourself get stronger.

Logr is a gym log for iPhone. Log a set in three taps, one-handed, with no signal, and see the numbers that actually followed.

The Train tab of the Logr app: a session in progress at 13:06 elapsed, and the last seven days at a glance, five sessions, 96 sets and 58’200 kg of volume.

Start a session. Log the set. Move on.

Mid-session, the next set is the only thing that matters, so nothing else competes for the screen: elapsed time, exercises, sets done. Finish, and the week reads at a glance.

Illustrative sample data from a debug build, not a real athlete.

The Train tab of the Logr app: a session in progress at 13:06 elapsed, and the last seven days at a glance, five sessions, 96 sets and 58’200 kg of volume.

Set up on instruments, not forms.

The first minute asks a few questions, and every answer is a control you can feel. Each one ticks under your thumb as you move it.

A wheel for your age.

Spin it. Every detent ticks, and the chosen year sits in a lit ring.

The age question in Logr: a vertical number wheel with 20 selected in a lit ring.

A tape for your height.

Pull the tape or type the number. The switch reads it back in cm or ft in.

The height question in Logr: a vertical measuring tape reading 175 cm, with a cm and ft in switch.

A ruler for your weight.

Scrub to the half kilo. The ruler ticks to your hand and stops at its ends.

The weight question in Logr: a horizontal ruler reading 75.0 kg, with a kg and lb switch.

Keys for what hurts.

Six switches, head to toe. A lamp on each one shows which are on, so a bad knee and a bad shoulder can both be true.

The pain question in Logr: six keys in two columns, back, hip and knee on the left, shoulder, elbow and wrist on the right, each with a lamp.

Only numbers you actually lifted.

One flattering figure costs the credibility of every other figure. Logr shows what it can count, and says plainly what an estimate is.

The week at a glance in the Train tab: five sessions, 96 sets, 58’200 kg of volume.
Volume
Completed working sets only. Warm-ups, and sets you planned but never did, are left out on purpose.
Records
A record is a set you logged, never a plan you wrote. Editing a routine afterwards cannot rewrite what you performed.
Estimated max
An Epley estimate, shown as a progression signal and never as a weight to load a bar with. It gets vaguer above ten reps.
Units
Weights are stored in kilograms, always. Whether you read them in kg or lb is your call.

Yours, on your phone.

A gym is the worst network a phone routinely visits, so Logr is built for the basement first.

  • Written to the device first.

    Every set is saved on your phone the moment you log it. Nothing in the app waits on a request.

  • No account required.

    Sign in with Apple or an email link if you want to. Logr is fully usable without either.

  • Never held hostage.

    Your training history is yours. It is not something a lapsed subscription gets to keep.

Get stronger on the record.

Logr for iPhone. Every set as it happened, and the numbers that followed.
