How it works
Three steps, then you just train.
Say it
Tell Fitlyze what you ate or what you want to do, in plain words. Or send a photo.
It works
It logs your food, builds your plans, and adjusts behind the scenes as your week changes.
You train
Show up and do the work. The tracking, the math, and the planning are already done.
The coach
Say it, snap it, or just ask.
Every way you'd tell a friend works here. Say it out loud and watch it turn into text, snap your dinner, or type three words — the coach logs it, remembers what matters, and builds you a plan when you ask.
-
Three ways to log
Voice, photo, or plain words. No barcode scanner, no database safari.
-
It remembers you
A sore knee, a hated food, last week's numbers — saved to memory and used in every answer.
-

Training
Every set counts. Literally.
Your program lives on your phone, not on a clipboard. Check off sets with reps, weight, and RPE mid-session, flip between day, week, and whole-plan views — and watch the body map shade in the muscles you've actually trained.

Nutrition
Your day, already planned.
The coach builds your nutrition plan with daily targets that match your goal. Then the day fills itself in: meals log as you eat them, the calorie ring and macros climb, water gets counted, and your streak stays alive.

Under the hood
There's a whole team behind the chat.
Ask for something big and Fitlyze doesn't guess. It hands the work to specialist agents, one for nutrition and one for training, then brings their answers back to you as a single plan that actually fits together.
You get one answer. A real coaching system makes it.
Nutrition specialist agent
Built a 30-day cut, about 2,100 kcal a day
Workout specialist agent
Built a 4-day upper / lower split
Why we made it
Tracking shouldn't feel like a second job.
Most apps hand you a giant food database and an empty log, then leave the actual work to you. Searching, scanning barcodes, guessing portions, second-guessing the plan. It's no wonder most people quit by February.
Fitlyze flips that around. You talk, it works. Tell it what you ate or what you want to do, and it takes care of the logging, the planning, and the adjusting in the background.
The app should do the work. You just train.
We're a small team building this carefully, and right now you'd be one of the first people using it. If that sounds like your kind of thing, come build it with us.
FAQ
Questions, answered.
Do I have to count calories myself?
No. Describe your meal in a sentence or send a photo, and Fitlyze works out the portions and macros for you.
Can it build my nutrition and workout plans?
Yes. Ask for a plan and Fitlyze builds your nutrition and training around your goal, then keeps adjusting both as you go.
Does it track my workouts too?
Yes. Log your sets, reps, and weights as you train, and Fitlyze keeps your workouts and nutrition working together.
Is my data private?
Yes. Your data stays yours. We never sell it or use it to train other companies' AI, and you can export or delete it whenever you want.
