HOW IT WORKS

Set up once. Then just train.

01
Tell it how you train
Your goal, your days, and the gear you have — or scan the room and let Fittrexx read the equipment for you.
02
Snap meals, log sets
Photograph the plate, say what you ate, or type it. In the gym, enter weight × reps with last time shown beside every set.
03
Watch the week stack up
Every session ends with a verdict against last time. Every week lines up against the one before. The plan adapts from there.

The first fitness app that sees what you eat, understands your space, and adapts every workout to you.

AI MEAL SCANNING

Snap it. Log it. Done.

Point your camera at your plate — or just type what you ate. Fittrexx reads the food and logs calories and macros in seconds, either way. No searching, no guessing.

STRENGTH LOGGING

Log every set.

A fast, set-by-set tracker built for serious lifters. Enter weight × reps for each set, see your previous performance inline so you always beat last time, hit the built-in rest timer, and get a celebration the moment you set a new personal record.

WHAT ARE YOU TRAINING FOR?

Pick a goal. See how the app bends to it.

Beat last time, every session.

Progressive overload is the whole game. Fittrexx puts your previous set beside the one you are doing and tells you, live, whether this session is ahead.
