A Golden Crow product

Your gym fits in your pocket

Coaches build the week from the backoffice; clients run it, log it and measure it from their phone or Apple Watch. With a coach or on your own.

Why we built it

Training plans get lost between the spreadsheet and the camera roll

The coach builds the week in a spreadsheet. The client screenshots it, and the screenshot disappears into the camera roll. At the gym nobody remembers last week’s numbers, and the coach only finds out how it went at the next check-in.

GC Fitness closes that loop: the coach assigns the workout, the client opens it, hits play and logs every set. What gets logged reaches the coach right away — weight, reps and the real duration of each session.

And it works just as well without a coach: clients build their own routines, repeat them whenever they want, and track progress with the same charts.

Four things the app does well

No endless menus: it is built to be used one-handed, between sets.

With a coach or on your own

With a coach, they build your week and you just hit play. On your own, you build your routines and repeat them whenever you like. Same app, same data.

Friction-free logging

Reps, weight, one check. The app shows what you did last time, computes volume, and starts the rest timer by itself when you close a set.

Progress measured, not guessed

Sets per muscle group, volume, body weight and guided progress photos. After a month you don’t guess — you know.

Habits that stick

Daily habits live on the same screen as the workout, with streaks and reminders. Training is one part; the rest of the week counts too.

Training

The session, as the client lives it

Open it, hit play, and forget about the app until the next set.

Sets, reps and weight

One tap per set, with last session’s numbers right beside it so you know whether to go up.

Automatic rest timers

The timer starts on its own when you close a set, showing what comes next and at what weight.

Coach notes in context

Each exercise carries its own cue, instead of a separate PDF.

Supersets and blocks

Grouped exercises run as a block, with the rest where it belongs.

Measuring

Every logged set becomes a line on the chart

Progress stops being a feeling and becomes something you can look at.

Sets per muscle group

Week by week, with the target range marked, so an undertrained muscle is obvious at a glance.

Volume and body weight

In the same place as everything else — no second app, no second spreadsheet.

Week projection

What is still ahead based on already-assigned workouts, drawn as a dashed line.

Guided progress photos

Front, side and back, always in the same pose, so the comparison actually means something.

On the wrist

The phone stays in the bag

The Apple Watch app is not a mirror: it logs on its own and syncs when the connection is back.

Log from the watch

Reps and weight with the Digital Crown, the check with your thumb.

Rest follows you

The countdown and the next set show up on your wrist, with a haptic tap when time is up.

A real workout

The session is recorded as a HealthKit workout, with heart rate and calories.

Data and privacy

Training data belongs to the person training.

  • Sign in with Google or Apple; we never store passwords.
  • Apple Watch health data stays on the device and in HealthKit.
  • Progress photos are visible to the client and their coach only.
  • Account and full data deletion from inside the app.
  • We do not sell data or use it for third-party advertising.
