Help us test it, the most detailed lifting tracker

logr is a workout logger built on hypertrophy research, for evidence-based lifters. It records every variable that changes what the numbers from a lift mean, and shows how they add up over months.

iPhone only, delivered through TestFlight. One email when your invite is ready. Nothing else, ever.

the problem

Numbers that mean nothing.

  • Big numbers get the applause. Total volume goes up and the app celebrates. Whether each muscle got enough hard sets this week goes unsaid.
  • Too little gets recorded. Most logs keep the exercise, the weight and the reps. The machine, the setup and the way you performed the lift are lost, so two sets that look the same often weren't.
  • One session at a time. Most trackers are built around today's workout. Muscle is built over months, and that view is missing.
What most logs keep

Incline Press · 100 kg x 8

What happened

Incline Press · Plate Loaded · Prime

bilateral · peg 3 · seat 4 · neutral grip · tempo 3-1-1-0

100 kg x 8 · 1 RIR

A log that can't show you any of this isn't telling you much. Lifters who care about that outgrow their tracker.

what logr does

The detail, and the long view.

First, the basics, because a logger has to get progressive overload right: last session's numbers beside every set, rest timers for each set type, PRs flagged when you finish, and templates.

Then come the details only logr captures, and the long view they make possible.

The detail

01

Machine-level history

Every set is tied to the equipment model you used, by load type, brand and model. History and equipment settings are kept per machine, and one exercise can be compared across two of them.

02

Executions

An execution is how you perform a lift: a grip, a body position, a technique. Each keeps its own history. Sets can be bilateral, unilateral or alternating, with tempo in four phases.

03

Any exercise, any equipment

New exercises appear all the time, often on machines built for something else. Create your own, link it to a real machine and record the attachment, GymPins and cuffs included.

The long view

04

Sets per muscle group

This is the weekly number we put first. Set a target range per muscle group and logr marks what falls under it and what goes over. Warmups never count.

05

Splits as a schedule

Plan by weekday or as a repeating cycle, rest days included. Your calendar shows planned days, the dashboard shows the next workout, and a missed day can re-flow or stay put.

06

Progress over months

logr charts every exercise and machine, flags PRs with an estimated one-rep max, and tracks average RIR or RPE, muscle frequency and your weeks across the year. One hard session barely means anything here.

You don't have to be advanced to use it, or call yourself a science-based lifter. The simpler workout view is weight and reps, the advanced view adds the rest, and you can switch anytime.

Moving over is quick too. logr imports your history from existing tracking apps, and it can read a workout template out of any screenshot, wherever it came from.

what we're asking

What being a tester actually means.

Invites go out in small batches before the App Store release. If you train for hypertrophy and already log every session, or have been wanting to start, you're exactly who we want.
