Get answers
from your data.

Your coach reads your actual logs — food, mood, workouts, sleep — and gives you answers grounded in your own numbers, not generic advice.

"What should I eat to hit my protein today?"
"How hard should I push in today's workout?"
"Recommend a high-protein dinner under 600 calories."

Questions

Things people ask.

Is Zenthfit available on Android?

Not yet — Zenthfit is iOS-only for now. We're focused on shipping the best possible experience on iPhone first. Android is on the roadmap, and you can sign up to be notified the day it launches.

How is the AI coach different from ChatGPT?

The coach reads your actual logs — meals, mood, sleep, workouts, weight — and gives you advice based on what you're doing right now, not generic answers. It knows your goal (gain muscle, lose fat, etc.) and remembers your patterns over time.

Does it sync with Apple Health?

Yes. Connect Apple Health (and optionally Garmin and Strava) in the app and Zenthfit pulls in your steps, workouts, sleep, and heart rate automatically. You stay in control of what's shared — disconnect anytime.

Is my health data private?

Yes. We encrypt your data in transit and at rest, and we never sell it. AI conversations are processed under strict provider agreements and aren't used to train public models. Read the full privacy policy.

What happens to my data if I delete my account?

It's permanently removed from our active systems within 30 days. You can also export everything to CSV before you go — one click from the account page.

Who's behind Zenthfit?

A small, independent team that wanted a fitness app that didn't feel like a spreadsheet. Got feedback or a feature request? Reach us at support@zenthfit.com.
