You build the programme
Workout plans with sets, reps, rest, coaching cues and your own demo videos. Meal plans with a calorie target and macro split. A supplement stack for each client.
The coaching app for personal trainers · iPhone
Your programme in their pocket. Every rep back on your screen.
CubeFit is one app with two sides. You build the workouts, meal plans and supplement stacks. Your clients train with them, set by set, and everything they log lands on your roster.

How it works
One loop. Two sides.
You write the programme on your phone. Your client trains with it on theirs. What they lift comes straight back to you, so next week's plan starts from real numbers.
02Client
They train with it
The guided session puts one exercise on the screen. They log every set on a big number pad, rest on a timer, and see “+2.5 kg on last time” before they leave the rack.
03Coach
You see every rep
Each client's sheet shows every set they logged, their bodyweight by week, and the sleep and resting heart rate they chose to share. No screenshots sent over chat.
For coaches
Run your whole roster from your phone.
Plans, meals, supplements, sessions and every client's numbers, in one app built around the way personal trainers work.
Coach dashboard
A to-do list, not a report.
The first screen tells you who trained, who's on track this week, and who has gone quiet.
- Three numbers that matter
Trained today, active this week (as 3/9), and sessions booked.
- “4 clients need a nudge”
Anyone with no session logged in four days or more is flagged. One tap opens your roster.
- Quick actions
Session Scheduler, Subscription and Manage Clients, one tap each.
Trained today, active this week, and who needs a nudge.
Google Calendar + Meet
Session Scheduler: book and notify.
Book 1:1 calls, check-ins and form checks from the dashboard. Pick a client, a date, a time and a duration. Before you confirm, it tells you exactly what the client will receive. Connect Google once, and the calendar follows the session for its whole life.
The button can't double-book on a double tap. All Upcoming Sessions lists everything, one tap to reschedule or cancel.
- 01Book
Pick the client, date, time and duration. Google Calendar creates the event and a Meet link, and the client gets an email invitation and a push notification.
- 02Reschedule
The same calendar event moves. The Meet link stays the same, and the client is notified.
- 03Cancel
The calendar event is deleted and the client is told.
- 04Remind
The client's phone reminds them 30 minutes before the session starts, even with no signal.
For clients · free
The app your clients open every day.
Today's workout, today's meals, water, supplements and an eight-week view of their progress. Free for every client you coach.

The centrepiece
The guided session. Built for the gym floor, not the sofa.
A full-screen mode for training with the phone propped against a rack. At the end, a Session complete summary names the lifts that went up.
- One exercise fills the screen
Prop the phone on the rack. The weight field is already in front of you.
- Set-by-set logging
Kilograms and reps on a large number pad, then “Set N done”.
- Rest timer
Starts after each set with the coach's rest time, or 90 seconds. Skip rest ends it early.
- “+2.5 kg on last time”
Every lift is compared with last time, and a “number went up” moment pops up when it beats it.
- Knows the exercise
A plank asks for seconds, not reps × kg. Bodyweight moves don't demand a weight.
- Watch the demo
The coach's video plays without leaving the session.
- Skip and come back
Skipped exercises come back before the session lets you finish.
- Leave halfway, lose nothing
Every tick is saved. The session resumes at the first unfinished exercise.
Today, at a glance
A day streak, sessions this week as 2/3, bodyweight against last week, and the daily calorie target from the diet plan.
- “1 session left · this week · 2 of 3 done”
- The next coaching session, with a reminder 30 minutes before
- Notifications for bookings, reschedules and cancellations

Apple Health
Recovery data, with consent.
When a client connects Apple Health, CubeFit shows their sleep, resting heart rate, steps and HRV next to their training. You see it only if they choose to share it.

Share with my coach
Lets your coach see your sleep, resting heart rate and steps
- Read-only
- CubeFit reads what it shows and never writes to Apple Health.
- Off until the client says so
- The coach sees recovery data only after the client turns on “Share with my coach”.
- Real sleep, not time in bed
- Sleep stages are counted and overlapping sources merged, so a Garmin plus an Apple Watch don't double-count a night.
- Your wearable already works
- Garmin, Whoop and Oura write into Apple Health, and CubeFit reads from there. iPhone only.
