Day 1 is coming.

How NYNTI gets to know you

The more you log, the more precise it gets.

Day 1

You say where you want to go

Goal, time, equipment and level. What you don’t like goes, what you want to protect gets protected. Then your first day is ready.

From day 15

What you really burn

From complete food days and your weight trend, NYNTI works out what you actually burn. Until then, the formula counts.

From week 3

Calories that follow your trend

NYNTI looks at your weight trend and adjusts in small steps. It only lowers them if you’re actually logging your food.

Every Sunday

Your week gets rethought

Was it too easy or too hard? Your answer and your data decide what next week looks like.

A day with NYNTI

Open it in the morning. Know what’s on.

Today

One glance and the day has a plan. No wondering whether it’s legs or a rest day.

  • “Ready today” shows from 0 to 100 what your body has to give, with or without a watch
  • Your main goal and where you stand, always in view
  • Check in in the morning, finish the day at night

Training

A plan that fits your basement. Gym, living room or park: it builds itself from what you have.

  • Over 250 exercises with pictures and guidance
  • Every exercise shows what you managed last time
  • A little heavier week by week, with no maths on your part

Food

Cook like a chef, count like a coach. You always see where you stand and what’s still possible today.

  • Calories, protein, carbs and fat at a glance
  • Omnivore, vegetarian or vegan
  • Log by search or barcode, on the Coach plan by photo too

Recipes

Food that tastes like food, not like a diet. Written by a chef, matched to your protein target.

  • Nutrition, ingredients and method step by step
  • Add it to your day with one tap, the app does the maths
  • Don’t fancy something? Just swap it

Check-in

Two minutes in the evening, and your plan knows how your day really went.

  • Hunger and energy from 1 to 5
  • Log training afterwards, including what wasn’t in the plan
  • With a watch or ring, sleep, steps and pulse come in on their own

Running

From your first 5K to the marathon: every run sits in the app with its distance and pace zone.

  • Every session explained, from easy runs to strides
  • Plus race preparation for fitness races like HYROX or ATHX
  • On the Coach plan, your runs go straight to your Garmin

Sunday

Your short weekly wrap-up: how did your week go?

  • Active days, strength sessions and kilometres at a glance
  • Was training too easy, just right or too hard? How are body and mind?
  • That shapes your next week. Feeling flat even though your watch says green? Then how you feel counts just as much

Your path

Your goal, your history, your trend. This is where you see what the weeks have really done.

  • Your weight trend since day 0, with your goal as a line
  • Swings of 1 to 2 kg a day are normal, the trend is what counts
  • Your 90 days in the calendar, milestones as stars

Who’s behind it

Built by a chef who trains.

Behind NYNTI is Alex: personal trainer, nutrition coach and a chef for 15 years. What he has learned working with his clients went into this app. And if you want someone at your side, that’s possible too: 1:1 with him.

Watch, chat, personal support: you give each permission separately and can take it back.

Questions.

Do I need an iPhone?

No. NYNTI also runs in the browser on any phone and computer. The iPhone app is coming to the App Store soon, with Android to follow.

What does it cost?

Basic is €12.99 a month or €99.99 a year, Coach €19.99 a month or €159.99 a year. At launch you get a 14-day free trial, and you can cancel online at any time. Premium with Alex has an individual price that you get on the free 15-minute call.

Which watches and rings work?

Garmin connects directly. In the iPhone app, Apple Health adds Apple Watch, Oura, Whoop, Amazfit, Withings and anything else that stores its data there. In the browser, only Garmin works. Samsung and Pixel Watch follow with the Android app. It works without a watch too.

Who answers in the chat?

The NYNTI AI, around the clock, on the Coach plan. If you want a human at your side, there’s premium coaching with Alex.

I don’t have much time. Is that enough?

That’s exactly what the plan is for. You say how much time you have, and it’s built around that. The evening check-in takes two minutes.

Do I have to give everything up?

No. There’s a chef behind NYNTI. Omnivore, vegetarian or vegan: you swap what doesn’t suit you, and the app does the maths.

Does NYNTI replace a doctor?

No. NYNTI is not a medical device and doesn’t diagnose anything. If you have symptoms, a medical condition or are pregnant, check with a doctor before training.

Is NYNTI available in German too?

Yes. NYNTI is available in English and German.
