Invite-only · Perth
One tap logs a set. Your scale, ring and watch fill in the rest. Trends under the day-to-day noise, projections with honest ranges, never a promised date.
For people who lift and want their body data read honestly, with the noise taken out.
Weight trend
Goal 82.0 kg: in about 3 to 6 weeks at −0.50 kg a week. A range, not a date.
Example data, for illustration. Not a real result.

Built from a tape, not a photo.
The product
A logger that keeps up with the session, body data that arrives on its own, and a short, plain read on what it all means.
Log
Last session's numbers on screen, weight and reps on big plus and minus buttons, and a rest timer that starts itself.
Sync
Scale weigh-ins, sleep, heart rate variability, resting heart rate, steps, blood pressure, watch workouts and daily nutrition, gathered in one place.
Passive feeds run on the founder's account today and open to members as they are ready.
Read
A short morning summary after your weigh-in, a weekly review, and findings ranked by how much they matter, so you are not reading charts at 6 am.
Insights are information, not medical advice.

How it works
No menus to dig through and no spinner between sets.
The one thing that matters this morning sits on top: a weigh-in due, a session due, or how you recovered. Start is one tap away.
Weight and reps come prefilled. Adjust with plus and minus, tap Log set, and the rest timer runs inline with the next target under it.
Machine taken? Swap, add, reorder or skip from the exercise sheet. Corrections happen after the workout, not between sets.
Volume per muscle, lifts against your trend weight, and body data with honest ranges land in Progress and Body.
In the app
Today puts the one thing that matters on top. Body shows the trend under the daily bounce, with an honest range on the projection.
Your data
No paywalled exports, no one-way doors. Everything you log stays yours, and you can leave whenever you like.
Questions
Apple Health, including data from Garmin, Withings and Cronometer that flows through it, and Oura through its own connection. Tape measurements and manual entries sit alongside. Passive feeds run on the founder's account today and open to members as they are ready.
No. Insights are information. Patterns are called associations, never causes, and projections come with ranges, not promised dates. Talk to a professional about your health.
Your account and training data are stored in Sydney. You can export everything in one tap, or delete your account yourself, both from Settings.
Logging is built to keep working without signal and sync when it returns.
About
Ex personal trainer. Moved into tech. Got fat. Spent the last 15 months rebuilding the body I wanted in my 20s. It's never too late.
ITBG Fit is the tool I wished I had through that rebuild. Every training app I tried either treated me like a beginner or buried the data I actually wanted under streaks and confetti. So I built my own, between sets, on a phone, in the gym.
Every rough edge gets found in a real session and fixed before the next one. That's the ITBG Labs way.

I have always been into fitness, data and AI. I wore every tracker going and logged everything, and none of it talked to each other. Thousands of data points that never taught me a thing.
This app started as a challenge to myself: build an app in the gym, between sets, with AI tooling. Version one was born on the gym floor. I refined it session by session, then wired my whole stack into it until it was something I actually wanted to use.
In November 2024 I weighed 106.8 kg. I rebuilt myself with what I learned as a qualified personal trainer (Cert III and IV in Fitness), and I know how hard the middle part is. ITBG Fit is the data geek, the trainer and the bloke who has done it, in one tool. If that sounds like you, tell me what you train and I will read it myself.
