For optimizers, biohackers & serious trackers

The connection between what you eat and who you become.

Every meal, workout, and weigh-in is a point in a line. TRĀCE draws it — and shows you where it's heading. Ask what tonight's wine does to tomorrow's scale. See fat trajectory from your actual protein intake. Catch the pattern before the plateau.

The problem with fitness apps

Logging data is easy. Knowing what it means is the hard part.

Every tracker shows you numbers. Weight, calories, macros, sleep. Then leaves you to figure out what they mean. TRĀCE does the connecting.

Other trackers

Show you what happened. Totals, graphs, a streak counter. You still don't know why you plateaued, what to eat tonight to hit your protein goal, or what tomorrow's scale will say.

TRĀCE

Shows you what to do about it. Ask what a glass of wine does to tomorrow. See the fat trajectory from your actual protein. Get specific meal suggestions that fit your remaining budget — pulled from food you already have.

What makes it different

Six things no other tracker does well.

Ask TRĀCE anything

“If I eat 5 hand rolls at Kazunori, what does that do to today?” Get a specific answer against your real numbers, in 10 seconds. Follow-ups work in-thread.

Projection engine

See your weight and body fat on specific future dates — based on your actual eating, not an assumed deficit. Adjust calories or protein and watch the forecast move live.

Voice-first logging

Tap and say “two scrambled eggs, half a sweet potato, splash of almond milk in coffee.” Done in 4 seconds. The parser knows your Pantry and uses your real brands.

Smart coach

Every day, one concrete suggestion built from your actual day. Not a generic quote. “You're protein-short — scramble 3 eggs with spinach from your Pantry (~277 cal, 25g protein).”

Biometric sync

Withings weight, body fat, muscle mass, visceral fat, vascular age. Apple Health workouts, sleep, resting HR, steps. Pulled in automatically — no re-entry.

Snap & forget

Take a photo of a food label and TRĀCE reads it. Build your Pantry once, log by name forever. Barcode scanning for everything else.

Ask TRĀCE

Your coach, in your pocket.

Nobody else does this. Ask a question in plain English. Get a specific answer that uses your actual numbers.

If I have 5 hand rolls at Kazunori, what does that do to today?

Kazunori hand rolls run ~130 cal each. Five rolls: ~650 cal, ~25g protein.

Add that to your 323 cal logged — you'd be at 973 cal / 53g protein, about 227 under your 1,200 target with 37g protein to go.

Scale tomorrow: expect +0.5–1.5 lb water weight, gone in a day. Real fat story: that's 1,100 cal under maintenance, so ~0.31 lb of fat lost today.

Solid lunch choice. Chase the remaining protein with shrimp or a lean snack tonight.

How it works

Three steps. Then it runs itself.

  1. 01

    Set your goal

    Enter your current weight, body fat, and where you want to be. TRĀCE calculates your maintenance and a safe deficit. You pick the pace.

  2. 02

    Log by voice

    Tap and say what you ate. Snap a label. Scan a barcode. TRĀCE reads it, pulls from your Pantry, and keeps every number consistent.

  3. 03

    See where you're going

    Daily edge, weekly trajectory, body-fat forecast. Ask questions when you need to. Watch the number move toward where you said you wanted it.

Stop logging data. Start reading it.
