Javix

Your AI trainer, nutritionist and gym crew — in one app.

Workouts built from the equipment you own, every muscle section covered, and a coach that rewrites tomorrow from what you logged today.

Dumbbell biceps curl
Barbell overhead press
Bent-over row
Dumbbell front raise
Core plank
Overhead dumbbell press
Barbell bench press
Chest fly
Dumbbell shrug

Every one of the 1,300+ exercises animates like this — with the working muscle lit as it moves.

One app, the whole picture

Most apps hand you a plan. Javix keeps rewriting it.

Six systems, one coach. Training, food, recovery and motivation all read the same history — so a hard week of squats changes what you eat, and a missed back day changes tomorrow's workout.

The core idea

A muscle isn't one thing

Train "chest" and you'll grow the middle. Javix treats every muscle as its regions and spreads your work across all of them, so nothing gets left a year behind — unless you tell it to prioritise.

3D & activation

See the movement before you load the bar

Every exercise ships with a looping animation that shades the working muscle as the rep plays — so you know where it should be burning before the set tells you. Rotation, zoom and slow motion arrive with the 3D models.

Nutrition

Log a plate, not a spreadsheet

Photograph the meal and Javix estimates calories, protein, carbs, fat, fiber, sugar, sodium and micronutrients. Then it watches the gaps and tells you what to eat — around your diet, your allergies and your goal.

Three ways to log

Photo, barcode or search. Whichever is fastest with one hand.

Nutrition dashboard

Daily calories and macros, fiber, water, weekly averages and full meal history.

Water tracking

A tap per glass, and a nudge on the days you forget.

Fixes, not guilt

"One cup of milk closes your protein." Practical food you already have, never a lecture.

AI Daily Coach

Your incline dumbbell press is up 15 lbs this month — today's weight went up with it. Your lower chest got 35% less volume than your upper chest, so I added one lower-chest movement. And you've hit your protein six days straight.

— what Javix tells you when you open the app. No daily questionnaire, no check-in form. Tap AI Insights on anything to see exactly why it changed.

Community

Training is easier with people in it

Ranks, streaks and challenges for the days you're motivated. Friends, teams and a real gym partner for the days you're not.
