Human coaches in the loop

The everything app for everyday athletes.

An AI coach that lives on your iPhone. It builds your training and meal plan, logs food from a photo, reads your watch — and rewrites tomorrow based on what you actually did today.

The arsenal

Everything your old fitness apps wished they were.

One app. Training, nutrition, recovery, coaching — talking to each other instead of living in five different tabs.

01 · Plan

One assessment. Your whole plan.

A 2-minute assessment — goals, schedule, equipment, injuries — becomes your custom training, nutrition and recovery plan: a real, periodized program built around your life.

Personalized training plan
02 · Log

Logs everything.

Food, activities, sleep, water, biomarkers and more — all in one place. Snap your plate, tell the chat "did 5x5 squats at 80kg", or let your watch report in. Logging takes seconds, not willpower.

03 · Sync

Connects to your wearables.

Apple Watch, Strava, Oura, WHOOP, Fitbit — connect once and your recovery and workout data flows in on its own. Your coach plans around what your body actually did.

Readiness, sleep, strain & HRV synced automatically
Every workout your watch records, logged for you
One wearable, zero manual entry

04 · Coach

A coach that never leaves your side.

Coach OG answers anything, anytime — it remembers your injuries, your schedule, your weird food preferences. And it's never AI alone: real humans stay in the loop.

Add a certified human coach for $30/mo — they review your progress and fine-tune your plan.

Day zero → day ninety

Four steps. Zero guesswork.

01

Spill everything.

A 2-minute assessment: goals, schedule, equipment, injuries, food you refuse to eat. The more honest you are, the scarier-good the plan gets.

02

Your plan drops.

Minutes later you have a full training + nutrition program built for your body and your calendar — not a template with your name on it.

03

Track like it's nothing.

Photo your food. Tell the chat "did 5x5 squats at 80kg". Or do nothing and let your watch report in. Logging takes seconds, not willpower.

04

It evolves. So do you.

Every morning Coach OG re-reads your sleep, readiness and logs — then quietly rewrites today. You just show up.

Receipts

Real people. Real numbers.

Not stock photos. These are athletes on the plan right now.

Questions

Asked. Answered.

How does the AI coach actually work? +

Coach OG ingests your assessment, every log, and your wearable data, then runs it through a coaching model that periodises your training and nutrition. Real human coaches review the plans in the loop, so it never goes off the rails.

Is there really a free plan? +

Yes — forever. You get a personalised plan at sign-up, daily suggested workouts and meals, the full HYROX simulator, and progress viewing without paying a cent. Pro unlocks the 24/7 chat, photo logging and daily-adaptive plans.

How do I log food and workouts? +

Three ways: snap a photo of your plate, tell the chat in plain language ("did 5x5 squats at 80kg"), or let your watch report the session automatically. Most logs take seconds.

Which wearables does it support? +

Apple Health, Strava, Oura, WHOOP and Fitbit. Readiness, sleep, strain and HRV feed straight into your daily plan.

When is Android coming? +

Soon. iOS is live now and gets every feature first. Android is in active development — join via the app to get notified at launch.

How is this different from MyFitnessPal + a PDF program? +

A PDF never changes. MyFitnessPal never coaches. OnlyGains connects your training, nutrition, recovery and wearable data into one coach that rewrites your plan every single day based on what you actually did.
