The fitness tracker you can just talk to.

Log meals, workouts, and weight by chatting, like texting a friend who happens to be a nutrition nerd. Metrify's AI understands what you say, and real math does the counting. No dropdowns, no guesswork.

Everything counts. You barely have to.

Food, training, weight, and sleep in one app, logged in seconds by text, voice, photo, or barcode. Here is what each piece actually does.

Log by talking

Describe your meal in one sentence: "two eggs and toast with butter." Metrify parses it, matches every item against a 447,000-food USDA-backed catalog, and logs each one as its own entry with real nutrition data.

Every log comes back as a card you can edit or undo. Type it, say it with voice input, snap a photo of your plate, or scan a barcode.

Workout Lab: see every muscle you hit

Workout Lab is a full strength training system: build routines, log sets and reps, and track session volume and calories. Saved routines replay by name in chat, so "log my Push Day workout" logs its exercises, sets, reps, and weights.

Training history renders as a weekly muscle heatmap: front and back body diagrams where brighter means more of the week's volume hit that muscle. Progression graphs track each lift over time.

Progress that means something

Weight trends use a 7-day smoothed average, so daily water swings do not bury the real line. The projection decelerates as you lose mass, because maintenance falls with body weight.

Food, training, and sleep each get their own charts, and meals carry micronutrients too: fiber, sodium, iron, and more.

Your streak, on one heatmap

The adherence heatmap shows every logged day as a square: green when you hit your calorie goal, red when you went over, gray when nothing was logged. Tap any day to open its log.

Streaks come from the same data, so the chain you are building reflects what you actually logged.

Syncs with your watch and scale

Connect Apple Health or Google Health Connect and Metrify pulls in weight, workouts, steps, and sleep automatically. You approve what gets logged.

Steps are tracked as their own metric and never converted into exercise burn, so a synced walk cannot count twice.

Real math, not vibes

The AI reads what you meant. Deterministic formulas on your phone do every calculation: calories, macros, BMR, exercise burn, weight projections. The model never invents a number.

It doesn't just listen. It does the work.

An assistant without tools can only give advice. Metrify's assistant has them: it writes to your log, edits it, and reads it back. One day, one thread:

One thread: written, corrected, and queried. Every number is computed on your device, never guessed by the model.

"Same lunch as yesterday"

Pulls your actual previous entry instead of making you rebuild it from scratch.

Takes the rest of the meal from the picture and your number for the rice, without logging rice twice.

"Remember that I'm vegetarian"

Carried into every future conversation, stored on your device. Ask it to forget whenever you like.

Your body's data belongs on your phone.

Most fitness apps store everything you log on their servers. Metrify doesn't. Every meal, weigh-in, workout, and goal is stored on your device and never stored anywhere else.

  • All fitness data is stored on-device (food logs, weights, workouts, goals, custom foods)
  • No selling, no ads, no data brokers  ·  we couldn't sell your logs if we wanted to; our servers don't keep them
  • Delete the app, delete the data  ·  it was never stored anywhere else
