Your nutritionist's plan, built for a real day.
- For people following a planAn app that keeps it in your pocket and redoes the numbers when something changes.
- For nutritionistsThe practice where you write plans, follow your patients and see how it's going.
A sample day, with the numbers worked out by Rhybi's engine.
Your plan in your pocket, even when the day goes differently.
It redoes the numbers on its own
You eat more, skip a snack, eat out: Rhybi recalculates the meals still to come and suggests how to get back on track. What you've already eaten stays as it is, and you decide.


Logging takes seconds
A photo of the plate, the barcode, or a few words written the way you'd say them. An estimate stays marked as an estimate.

Your workout next to your plan
Follow the session set by set, on the same screen as your meals.

The shopping list writes itself
From the week's plan, sorted by aisle, for however many people you cook for.

Your nutritionist, one message away
Ask about the plan right there, and on the other side they see the same day you do.

And an olive grove that grows with you
It grows with the useful things you do, never with what you eat. If it's not for you, switch it off.

- Clinical notes, messages and questionnaires are encrypted: not even one of our administrators can open them.

Questions we get
Is Rhybi a calorie counter?
Is Rhybi a calorie counter?
No. A calorie counter knows the calories of whatever you type. Rhybi knows the plan you have to follow, and when the day changes it redoes the numbers.
Do I need a nutritionist to use Rhybi?
Do I need a nutritionist to use Rhybi?
No. If you have one, the plan comes from them and you message each other in the app. If you don't, you write the plan yourself or have it worked out from your needs. The rest works the same.
What does Rhybi cost?
What does Rhybi cost?
Right now it's free, and no feature is locked. Prices will come once we understand how it's used. People already on board will hear first.
Does my nutritionist see everything I log?
Does my nutritionist see everything I log?
They see what they need to follow you: the plan, what you logged, your measurements, your questionnaires. They do not see your credentials, and nothing tells them what you are doing minute by minute.
Does it work on iPhone and Android?
Does it work on iPhone and Android?
Yes, and it was built for the phone. It goes on your Home screen like an app and there is nothing to download from a store. On a computer it opens in the browser.
Can I delete my data?
Can I delete my data?
Yes, from your profile, whenever you want. Deleting takes the account and everything in it, and you don't have to write to us.
I'm a nutritionist: how do I start?
I'm a nutritionist: how do I start?
Open the professional area and leave us your registration number. We check it by hand. Once the account is open, you write the first plan and invite patients with your practice code.
Do my patients have to pay anything?
Do my patients have to pay anything?
No. In this phase neither side pays. When there are prices, you'll know before they do.
Can I take away the plans I wrote?
Can I take away the plans I wrote?
Yes. Every plan prints from the browser, and every patient can export their own data whenever they want. What you write stays yours and what they log stays theirs.
