What ZENTT does
Three things, one health record — your meals, your workouts and your bloodwork on a single timeline.
Food
Log a meal three ways: search for the food, scan the barcode, or take a photo and let ZENTT recognize it and estimate the portion. Calories and protein are counted for you.
Training
Log your workout in seconds and keep your records. Name your sessions whatever you call them. No plan today? Ask for one — built from your goal and your equipment, with a picture for every exercise. Connect ZENTT to your devices.
Health
Upload your blood test. Every result explained in plain language — next to what your lab calls normal, and next to what research links to better health. Keep your doctor visits, prescriptions and supplements in one place, and walk into your next appointment with a one-page summary already written.
Why one app instead of three?
Changing your body composition and improving your health come down to three things you can measure: what you eat, how you train, and what your blood says. Keeping all three in one place is what lets you compare them, track them over time, and see which ones are actually moving.
ZENTT doesn't diagnose: it keeps your history, with dates, so you and your doctor can review it together.
Every number says where it came from
Other apps show you a "healthy range" and don't say who decided it. ZENTT does.
Triglycerides under 100. The American Heart Association calls this optimal. The source is one tap away.
Ferritin 70–150. Widely used by coaches and clinics, but no published study behind it — so ZENTT says that, right next to the number.
Whatever your lab printed. Kept exactly as is.
Your lab says normal. Normal is the bare minimum. Start where optimal begins.
Frequently asked questions
What is ZENTT?
A complete health ecosystem for body recomposition and health optimization. Monitor, manage and optimize your macros, your training and your biomarkers in one place.
Is ZENTT a doctor or medical advice?
No. ZENTT organizes your information and shows published ranges with their sources. It never diagnoses or tells you what to take. When something needs attention, it says to talk to your doctor.
How do my lab results get in?
Upload your lab report, or type your results yourself: the marker, the value and the lab’s range. ZENTT knows 80+ biomarkers, and if your report has other tests, it keeps those too, under your lab’s own name. Every panel stays on record over time, and ZENTT reminds you when to re-test.
What do the colours mean?
Mint means inside the range. Orange means outside it. Red is used only for a published red line, a lab alert or a crisis line. Every range says where it came from.
Who sees my data?
You. ZENTT never sells your data. Nothing is shared with people unless you choose to: the Emergency QR shows only what you selected. Ask ZENTT uses an AI service to word its answers, and uses WHOOP data only if you turn that on.
Does it work in Spanish?
Yes. Every screen works fully in English or Spanish.
Do I need a wearable?
No. WHOOP and Oura are optional extras, with Strava and more coming soon.
How much does it cost?
ZENTT Pro is $24.99 a month or $179.99 a year, with a 7-day free trial. You can cancel anytime from your App Store or Google Play account.
