Lattice
Lattice is a training and nutrition mobile app that doesn't just measure whether you gain weight or strength, but whether your body progresses in balance. It detects which muscles fall behind, compares your left side to your right and adjusts your workout to correct it. Everyone gets their own plan from day one, logs what they eat with a photo and has an AI assistant that knows their history.
Your own plan from day one
The app starts with a guided three-step sign-up: measurements, goal, where and how often you train, your experience and the muscles you want to prioritize. From that, it builds a complete plan and explains why it's the right one.
- A weekly plan with training days, exercises and a suggested weight for each.
- A clear explanation of why that plan was chosen, without jargon.
- The plan can be accepted as is or adjusted by hand.
Today's balance
The main screen sums up the day in a four-axis radar: training, nutrition, recovery and consistency. At a glance you know what's going well and what needs attention.
- Asymmetry alerts when a muscle group progresses more than its opposite.
- Proportion goals, like shoulder-to-waist ratio, with their progress.
- A front and back muscle map showing how recently each muscle was trained.
- Weight chart, left and right symmetry measurements, and before-and-now progress photos.
Training with the right weight
Template-based workouts (Push / Pull / Legs, Upper / Lower, Full Body and more) that adjust themselves to your balance. During the session, the app tells you how much to load and why.
- Weight calculated for every set based on your previous session.
- Progressive overload suggestions once you've mastered a weight.
- Supersets, rest timer and one-tap logging for every set.
- Per-muscle ranks, from Bronze to Elite, that go up with your records.
AI on your side
Artificial intelligence is used where it actually saves work: measuring, logging and answering questions.
- Body scan: from a photo, it measures muscle balance and side-to-side symmetry, and adjusts the plan.
- Meal logging by photo, free text or manual entry, with estimated calories and macros.
- An assistant that knows your goal and your week, builds workouts and answers training and nutrition questions.
- Photos are stored in a private space; only the user can see them.
Training together
A community to stay consistent: friends, challenges and a weekly leaderboard.
- One-on-one challenges on an exercise, scaled to body weight so they're fair.
- Friends' activity with duration, volume and records, to cheer them on.
- Weekly leaderboard by training volume.
- Profile with explained calorie goals, Apple Health or Health Connect integration, and history import from other apps.
