FitMaxx: Health Tracking
Peptides, macros, blood work
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
Peptides with the syringe math done: every dose you log shows the units to draw. Plus food, workouts on your phone or Apple Watch, weight, sleep and blood work.
FitMaxx is the tracker for people running peptide protocols - with the syringe math done for you - and the one place for everything else you track: food, workouts, weight and progress photos, sleep and blood work.
PEPTIDES, WITH THE SYRINGE MATH DONE
Enter a vial's strength and the water you mixed it with once. From then on, every dose you log shows exactly how many units to draw on your syringe - no calculator app, no arithmetic mid-injection. See what is due today, where the next injection goes in your rotation, how many doses you took in the last eight weeks, and your weight since the protocol began. Supplements and vitamins sit alongside, scanned straight off the label. The doses are always yours: FitMaxx never suggests one.
YOUR DAY AT A GLANCE
Today opens on four rings - your food score, protein, workout and steps - and a to-do list of what is left: weigh in, take your doses, log your meals, train. The same rings live in a Home Screen widget with one-tap buttons to log a meal, start a workout or weigh in.
WORKOUTS, ON YOUR PHONE OR YOUR WRIST
Log lifts as exercises and sets with a body map of what each one works, and see where every muscle group stands, Beginner to Elite. Start a workout on your Apple Watch and log your sets right there, phone or no phone - your heart rate comes with it, and your wrist taps when the rest is over.
FOOD LOGGING THAT LEARNS
A private food library grows out of what you actually eat, so the second time it is one tap. Search USDA and Open Food Facts, scan a barcode, or photograph the plate and get an estimate with a range - every figure is yours to check before it is logged. Every food and every day gets a FitMaxx score.
WEIGHT, BODY COMPOSITION AND PHOTOS
Weight from a smart scale through Apple Health or typed in, a progress photo on the same screen, the trend in a plain sentence, and how much of what you lost was fat.
SLEEP AND BLOOD WORK
A FitMaxx sleep score every night, by stage. A lab report PDF read into a panel you check before it is saved, every marker tracked across the years, and a biological-age estimate from nine routine markers.
APPLE HEALTH FIRST
Your scale, your watch and Strava already write to Apple Health, so they count here too. Meals, weights and lifts you log here are written back.
A FASTING TIMER WITHOUT A CAP
For the days you fast: the timer runs as long as you do, and FitMaxx never rewards a longer fast - no streaks, badges or nudges for one.
YOUR DATA STAYS YOURS
Nothing you log is shared with insurance companies, employers or data brokers - there is no one to share it with. No ads, no analytics vendors, no tracking SDK. Delete everything in one tap from Settings.
FITMAXX PLUS
Everything above is free. FitMaxx Plus - $19.99 a month or $79.99 a year, billed to your Apple Account - lifts the free account's 20 AI answers a month (photo estimates, menu lookups, label reads, typed meals) and adds the lab-report read, the weekly coach note and the biological-age estimate. A subscription renews automatically unless it is turned off at least 24 hours before the period ends; manage or cancel it in your Apple Account settings.

FitMaxx does not give medical advice. It records what you did and states what changed.
