For iPhone · Reads Apple Health

Track it all.See what changed.

Peptide protocols, workouts, meals and macros, blood work, sleep and weight in one app. Logged in a tap, read from Apple Health wherever it can be, and turned into plain sentences about what changed - the part Health leaves out.

What it tracks

Six things, one app

Each one is a tab or a card, not a chart to dig for. Anything Apple Health already knows - the scale's weight, the watch's workouts, sleep, steps, heart rate - arrives on its own, so most days there is nothing to type.

Peptide protocols

Each peptide on its own schedule: what is due today, where the next injection goes in the rotation, how the dose has stepped over time, and weight since the protocol began. A reminder at the hour you choose, if you want one.

Workouts

Lifts as exercises and sets, with a body map of what each one works, a catalog of two hundred movements and a one-tap repeat of last session. Watch workouts land in the same list with what was measured.

Meals and macros

Calories, protein, carbs, fat and sugar against your targets. A food library that grows out of what you eat, a barcode scanner, and a photo of the plate that comes back as an estimate with a range you can edit before it is saved.

Blood work

Pick a lab report PDF and every result comes back as printed, for you to check before it is saved. Each marker is tracked across panels, and nine routine ones give a biological-age estimate beside your age, from a published formula.

Sleep

Every night by stage, the last two weeks side by side so you can see how much it moves, and last night as a card you can share - hours, deep, REM, when you went down and got up - without a score stuck on it.

Weight, with photos

From a smart scale through Apple Health or typed in, with a progress photo on the same screen. Then-and-now photos side by side, and a trend written as a sentence rather than a line to squint at.

Insights

Apple Health shows the numbers. FitMaxx says what they say.

Health keeps every reading in its own chart and leaves the reading to you. FitMaxx holds one part of your data against another - sleep after a workout against sleep without one, resting heart rate since a protocol started, the weeks under the calorie target against the scale - and writes the difference out with the figures it came from.

You sleep 48 min longer on nights after a workout.

+48min

7h 41m after a workout across 19 nights, 6h 53m otherwise across 33.

Last 60 days

Resting heart rate is 4 bpm lower since Retatrutide started.

−4bpm

68 bpm over the fortnight before, 64 bpm over the last seven days.

Since Jul 12

Down 4.1 lb over the last four weeks, about 1 lb a week.

−1.0lb / wk

Seven-day averages, so one heavy morning cannot move it. At this rate 195 lb lands around Jan 18.

Last 4 weeks

Weeks under the calorie target fell 1.2 lb a week; weeks over it rose 0.3.

−1.2lb / wk

6 weeks under the target, 3 over, weight read as three-day averages at each end.

Last 12 weeks

Bedtime is usually around 11:20 PM, within about 25 min either way.

11:20PM

Read off the last 14 nights.

Last 14 nights

Protein reached 180 g on 5 of the last 7 logged days.

5of 7

Averaging 172 g a day against a target of 180 g.

Last 7 logged days

Stated, never graded. Every line is a comparison with the numbers under it - "+9.9 bpm over 8 weeks", never "Poor". The app records what happened; it is not qualified to judge it.

Progress

Score for showing up

A streak of days with anything logged. Milestones that are dates, not badges: the tenth weigh-in, the fiftieth workout, every ten pounds down, a lift that beat every earlier one. Health keeps none of this.

At the end of a month, a recap in plain statements - days logged, steps a day, sleep a night, weight change from the first week to the last - ready to share as text. And last night's sleep as a card for the group chat.

Nothing here rewards a longer fast. The timer has no cap, and it earns no streak, badge or nudge - that is a safety call, and it is deliberate.

Also

Built for the long effort

Apple Health first

Weight, body fat, sleep by stage, steps, workouts, resting heart rate, HRV and VO₂ max are read from Health - which means your scale, your watch and Strava too. Meals, weights and lifts you log here are written back, so Health stays the record.

A fasting timer with no cap

For the days you fast: a timer that runs as long as you do, on the front screen while it runs, and an offer to log the meal that breaks it. The scale reads to 40 hours; 24 is a tick you pass.

Every reading has a screen

Tap resting heart rate, HRV, VO₂ max, steps or sleep and get the last three months, the weekly and monthly averages, the eight-week change and what the insights say about that one reading.

Privacy

Your data, on one server, deletable in one tap

FitMaxx is built and run by one person for a small number of people. There is nothing in it that makes money from your data.

  • No ads, no analytics vendors, no data brokers, no tracking SDK in the build.
  • Sign in with Apple only. The app never sees a password.
  • Two things leave the server, and only when you use them: a meal photo or a lab PDF goes to Anthropic's Claude to be read, and a barcode number is looked up in Open Food Facts.
  • Settings has a Delete account button. It removes every record, photo and PDF at once.
  • The whole policy is short enough to read: privacy policy · terms of use.
