AI health coach · iOS

Calorie counter,
intermittent fasting
and an AI health coach.

Photograph your plate, start a fasting window, track sleep and recovery. Derio brings it together in one iOS app — and tells you every morning what to do next.

Meet Derio Coach

An AI health coach
that knows your profile.

Ask anything and the context is already there: your meals, your water, your weight, your activity, your sleep and your last seven days of fasting. Derio answers like a coach who has been with you for months — not a chatbot meeting your day for the first time.

Analyse my day
You’re 30 g short of your protein target. Add a protein-rich snack around 4 pm and keep your fasting window open until 8 pm. Across your last 7 days you sleep better on the nights you eat before 8.30 pm.

Photo meal analysis

Point. Shoot.
It’s logged.

No database to dig through, no kitchen scale. Photograph your plate and Derio estimates calories, protein, carbs and fat, then fills in micronutrients. The meal lands in your day in seconds.

Wake up knowing

Intermittent fasting

Fast smarter,
not harder.

Pick a protocol — 16:8, 18:6 or your own — and follow every window with a calm circular timer. Fasting stages appear as the hours pass, and you can pause at the weekend without breaking your streak.

FAQ

Frequently asked questions

What to know before you download.

How does the photo calorie counter work?

You photograph your plate and Derio estimates calories, protein, carbs and fat in seconds, then fills in micronutrients. Every item and portion can be edited before you save the meal.

Does intermittent fasting work with Apple Watch?

Yes. Pick a 16:8, 18:6 or custom protocol and follow the timer on your Apple Watch or from a home screen widget.

Is my health data private?

The AI coach can run entirely on your iPhone with Apple Intelligence, so in that mode your health data never leaves the device. Derio syncs with Apple Health locally on your phone.

Can Derio replace medical advice?

No. Derio is a wellness and coaching companion, not a medical device. Always check medical questions with a qualified professional.
