Nutrition that trains with you

Know if you are fueled.
Not just what you ate.

Gauge reads what you eat and weighs it against your sport, your training load, and your target. Log by voice, photo, or text. The needle does the rest.

The Readout

Your day, on one dial.

Meals grouped, macros pinned at the bottom, coach digest up top. The gauge reads low or full. It does not judge.

Logging

Type it. Say it. Shoot it.

Plain words in, calories and macros out. Voice and photo logging for when your hands are full — or covered in peanut butter. Your usuals become one-tap meals.

Coach

A co-pilot reading the instruments.

Ask anything. Your coach reads live targets, your food log, your weight trend, and your training plan. Never guilt — just the readout and the next move.

Long run tomorrow. What should dinner look like?
Carbs are 80g short of target. Aim 120g at dinner — rice or a bagel closes the gap.
Done. Pasta it is.

Targets

Targets that train with you.

Rest day, easy day, quality, long run, race. The target engine moves your macros with the load. You are not on a diet — you are in a training block.

Plan import

Screenshot your plan. Fuel your week.

Paste your training plan or shoot a screenshot of it — from your coach, Runna, or the back of a napkin. Gauge turns it into sessions and rebuilds the week's fueling around them. Taper time? The deficit pauses, the carbs stay up.

Photo logging in Gauge: the camera framing a plate of salmon, parsed to 640 calories with macros
Photo logging

Point. Shoot. Logged.

Snap the plate and Gauge reads it — portions and all. Add what the camera can't see, like the oil it was cooked in. The photo is analyzed, then discarded. It never leaves the moment.

Your agent

Ask Claude. Get your real numbers.

Gauge ships its own MCP server — connect it to Claude or any agent you trust, and ask about your fueling from anywhere you think. Read-only, revocable, and the answers come from your live data, not vibes.

FAQ

Fair questions.

Is Gauge free?

The free tier logs up to 5 entries a day by text or voice, with day targets and Coach included. Gauge Pro — $9.99/month or $69.99/year — unlocks unlimited entries, photo logging, the Library, custom goals, water tracking, streaks, and editing past days. New subscribers get a 14-day free trial.

How accurate are the macro estimates?

Every estimate comes with its reasoning and sources — open any entry and tap "Why these numbers" to see them. Portions are adjustable after the fact, and telling Gauge what changed ("cooked in butter") re-runs the numbers. Like all nutrition data, they're estimates — built to be consistently close and easy to correct.

What happens to my meal photos?

They're analyzed to identify the food, then immediately discarded. Photos are never stored, and nothing you log is used to train AI models.

Does Gauge work with Strava and my health app?

Yes. Strava runs and rides sync the moment you finish and re-adjust that day's targets automatically, even with the app closed. Apple Health on iPhone and Health Connect on Android sync workouts and weight.

I lift. Is Gauge only for endurance athletes?

No — Gauge has a strength & functional mode. After training, answer one question (Easy, Moderate, or Hard) and your day's targets adjust. Endurance athletes get bigger carb swings with session length; lifters get steady targets that rise on training days.

Where does my data go?

Gauge runs on Claude under commercial terms: your food logs and training context power the features you use, and are never used to train models, never sold, and never used for ads. Precise location never leaves your phone. You approve exactly what's shared before the app starts, and can delete everything in one tap.

Can I cancel anytime?

Yes. Billing is handled by the App Store or Google Play — cancel in your store's subscription settings and Pro stays active until the end of the period you paid for. Cancel during the trial and you're never charged.

When is Gauge coming to Android?

Yes. Gauge is on Google Play, and on the App Store for iPhone. Same app, same subscription — Pro follows your account, not your handset.
