Compete With Friends
Challenge your mates, track leaderboards, and turn training into something you actually look forward to.
FITTIE.ai builds your workouts, tracks your results, and adapts your programme in real time — like having a world‑class coach in your pocket, available 24/7.
Tell us your level, goal, schedule, and what equipment you have. Takes 60 seconds.
A complete training and nutrition programme — built around you, not a template.
Log honestly. Your plan rebalances every week based on real performance.
Train anywhere — gym, home, or outdoors. Programmes built around the equipment you have, the time you've got, and the body you're in.
Challenge your mates, track leaderboards, and turn training into something you actually look forward to.
Your AI agent checks in, nudges you when you go quiet, and keeps you honest — without the judgment.
No cookie‑cutter programmes. Your plan is built around your goals, your schedule, and your results — and it adapts as you do.
Eating plans matched to your training load, goals, and preferences. Fuelling made simple.
Plans that adapt to where you are in your cycle — optimising performance, recovery, and energy across every phase. Train with your body, not against it.
Built inside an app that actually gets smarter the more you use it.








"I've tried every app going. FITTIE is the first one that actually changed my plan when I told it I was exhausted. Down 8kg in 10 weeks."
"The cycle‑aware plans are a game changer. I finally feel like my training is working with my body, not against it."
"My mate got me on this as a bet. Six months later I'm in the best shape of my life and he owes me £50."

I built FITTIE because life gets busy. Friends move overseas, family take different paths, schedules drift apart — and the gym, the one place we used to share, gets quieter.
FITTIE is how you stay connected and keep each other honest. Train together when you're apart. Compete, cheer, hold each other accountable — even when you're on opposite sides of the world.
And on top of that? No other fitness app does what FITTIE does. Most are generic, one‑size‑fits‑all programmes. If you're serious about getting the best out of yourself, your app should be too.

Both. Fittie scales the plan to your level — beginners get progressive intros and form cues, experienced lifters get periodised programmes with proper volume, intensity and recovery.
A calorie counter logs your food. A PT writes a plan once a month. Fittie does both — and the plan rewrites itself every week based on what you actually did, how you slept, and how you felt. It's coaching that adapts in real time, for less than the cost of a single PT session.
Every time you log a session — reps, weights, perceived effort, recovery — your AI agent rebalances next week's volume, exercise selection, and recovery days. Skip a week? It deloads. Smashing PRs? It pushes harder. It's your coach, not a static PDF.
Train anywhere — gym, home, hotel, or outdoors. Tell us what equipment you have access to and your plan is built around it. Bodyweight, dumbbells, full barbell, machines — Fittie works.
