Fitness advice you can actually trust.

The problem we set out to fix

Open most nutrition apps and you'll get a protein target, a calorie goal, and a supplement recommendation — all delivered with total confidence and zero sourcing. Some of those numbers are backed by decades of research. Others are marketing. You can't tell which, and that's by design.

We think that's backwards. The numbers that shape your health deserve a citation, or at least an honest admission when one doesn't exist.

What we built

Hitt Fitness brings the pieces of your health into one place so they can finally inform each other:

• An AI coach that computes your daily energy and macro targets from your own profile using the Mifflin-St Jeor formula.
• On-device nutrition label scanning powered by Apple Vision — your photos never leave your phone.
• Meal planning and tracking with smart swaps that fit your remaining calorie and protein budget.
• Workout logging across strength, cardio, HIIT, and mobility.
• Evidence-rated supplements — with a food alternative whenever the science is weak.
• Lab tracking that pulls your bloodwork from Apple Health and explains each marker against its optimal range.

How we think about privacy

Your data is yours. Label scanning runs on-device, your logs are stored locally, and we never pull from Apple Health unless you explicitly import it. See our Privacy Policy for the details.

A note on scope

Hitt Fitness is a wellness and fitness tool — not a medical device. We help you understand and act on your numbers, but we're not a substitute for a doctor. Always loop in a qualified healthcare professional for medical decisions.
