Your body changes.

Why Evolu exists

You've started a diet on Monday and quit by Wednesday. You've followed a workout plan that never changed, not even after a terrible night's sleep. The problem was never you. It was a plan that had no idea how you were doing. Evolu does, and it changes with you. 

01

It knows how you woke up

While you sleep, the ring tracks your sleep, your heart, and your recovery. No guesswork, no one-size-fits-all chart.

02

It learns from you

Every night and every workout teach Evolu a little more about your body. The more you use it, the more the plan feels like yours.

03

It tells you what to do

You don't need to read a single chart. Open the app and you'll know if today is a day to push, hold steady, or rest.

Evolu Ring

You'll forget you're wearing it. It won't forget a thing.

A light ring with no screen and no notifications that follows your body around the clock and sends everything to the app.

  1. Graphite stainless-steel Evolu Ring

    01Design

    Good-looking enough to never take off.

    Graphite stainless steel, slim, no screen. It goes with your wedding band, your watch, and your gym clothes. Sizes 7 through 14.

    Small on the outside. Packed on the inside.

    Inside, sensors track your heart rate, heart rate variability (HRV), blood oxygen, and skin temperature. Every night, right on your finger, without you lifting a finger.

    From your finger straight into your plan.

    The ring isn't there just to draw pretty charts. What it measures changes your day: how hard you train, what you eat, and when you go to bed.

The Evolu Ring is a wellness and fitness device, not a medical device. Battery life varies with usage and measurement frequency.

Sleep and recovery

Your night shapes your day.

While you sleep, the ring writes everything down: how long you slept, how much of it was deep sleep, how your heart behaved. By the time you wake up, Evolu has compared it with your other nights and gives you a score from 0 to 100 that says whether today is a day to push or to take it easy.

  • Nothing blinking on your finger

    The ring doesn't buzz, light up, or wake you. It just takes notes.

  • No charts to decode

    You don't need to know what HRV is. The app translates it and tells you what to do.

  • One bad night won't wreck your week

    Tomorrow adjusts and the plan keeps going. No guilt, no starting over.

  • Wellness, not diagnosis

    The numbers help you plan your day. For your health, your doctor is still your doctor.

The app

Everything you need to know today, on one screen.

Your workouts, food, sleep, and progress talk to each other, so you open the app and just know what to do. These are real screens from the app, shown with a sample account.

  1. 01Home

    Good morning. You already know how you're doing.

    Before coffee, the app shows your Energy score from 0 to 100, how last night went, and one simple line: what to do right now. It updates on its own in the afternoon and evening.

  2. 02Sleep

    Find out how you really slept.

    Not just “you slept 7 hours.” See your deep sleep, REM, every time you woke up, and how your heart spent the night. The app even suggests a bedtime that fits your routine.

    Evolu sleep screen with last night's stages: awake, REM, light, and deep
  3. 03Training

    The right workout for the day you're having.

    Slept well? Go heavier. Slept badly? Volume comes down and your week stays on track. Use the app's plan, build your own, or snap a photo of your trainer's program.

  4. 04Personal challenge

    Got a race on the calendar? We'll get you there.

    Your first half marathon, swimming 1 km, climbing a mountain. Tell Coach the goal and the date, answer a few questions, and get a week-by-week plan all the way to the big day. If the deadline is too tight, it tells you up front.

  5. 05Nutrition

    Eat well without becoming a calorie accountant.

    Snap a photo of your plate and you're done. Or scan a barcode, or import the meal plan from your dietitian. Your daily targets follow the workout you actually did.

  6. 06Evolu Coach

    Ask anything. It answers with your numbers.

    “How did I sleep this week?” and it shows you the chart. “My shoulder's bugging me” and it swaps the exercise. Coach remembers your conversations and only says the plan changed after checking that it really did.

  7. 07Progress

    Watch the results show up.

    Weight, measurements, photos, and body fat on one line, with a forecast of when you'll hit your goal. It's the kind of screen that makes you want to keep going.

Beyond training

Your whole day, in one place.

Medication, supplements, water, habits, how you're feeling. The stuff you used to jot in your notes app (or forget) now lives in Evolu, where it also helps explain why you woke up feeling the way you did.

Today's diary

Took your creatine? Drank your water? It's all here.

Medication, supplements, meals, training, and habits, each in its own place, with one tap to check them all off. Forgot to log something yesterday? The app asks what happened. No lecture.

Body signals

When something's off from your normal, you'll know.

The app compares your temperature, resting heart rate, HRV, and breathing rate with your own nights. Not with somebody else's average.

Apple Health and Health Connect

Your data is yours. It goes where you go.

Evolu pulls in steps, sleep, and heart rate from your phone and watch. Then it sends back everything it measures: workouts, ring data, body measurements, and meals.

Frequently asked questions

Got questions? We've got answers.

Here's what people ask us most about the ring, the app, the plans, and privacy.

Didn't find yours? Drop us a line: contato@appevolu.com

How does the pre-sale work?

It's simple: you reserve your Evolu now at the pre-sale price, which is only for people who buy before launch. When sales open, pre-sale orders ship first, in the order they came in. Reserve earlier, get it earlier.

Will the price go up after the pre-sale?

It might. The prices on this page are pre-sale prices for people who buy now. At launch, they may change.

What's the difference between the pre-sale and the waitlist?

With the pre-sale, you pay now at the lower price and get a spot in the first batch. With the waitlist, you pay nothing: leave your name, email, and WhatsApp, and we'll let you know when sales open, at launch pricing.

When will I get my Evolu Ring?

Pre-sale orders ship in the order they were placed. The first batch is expected to ship in November 2026.

What does the Evolu Ring measure?

Day and night, it tracks your sleep (stages included), heart rate, heart rate variability (HRV), blood oxygen, skin temperature, and activity. The app uses all of it to adjust your plan. Just a heads-up: it's a wellness device, not a medical device.

Do I need the ring to use Evolu?

No. The PRO plan works without any device and, if you wear a watch, pulls data from Apple Health or Health Connect. ONE comes with the Evolu Ring, so your sleep, recovery, and heart rate flow into your plan on their own, no extra gear needed.

Does Evolu work with Apple Health and Health Connect?

Yes, both ways. The app pulls steps, sleep, and heart rate from your phone and watch, and sends everything it measures back to Apple Health and Health Connect: workouts, ring data, body measurements, and meals. No duplicates.

What's the difference between PRO and ONE?

Same brains: training, nutrition, sleep, and progress all connected, with Evolu Coach. The difference is that ONE comes with the Evolu Ring, so your body's signals flow into the plan automatically. It's the full experience in a single annual subscription.

How do I pick my ring size?

The Evolu Ring comes in sizes 7 through 14, and you pick yours when you subscribe to ONE. Stuck between two sizes? Go with the bigger one: the ring should turn gently on your finger without squeezing.

How long does the battery last, and how do I charge it?

Up to 7 days with normal use and up to 15 days on standby. To charge, just set the ring on its wireless base and plug the base into a USB-C cable. Actual battery life depends on how often it measures and how you use it.

Can I wear the ring in the shower, the pool, or at the gym?

Yes. It's rated 5 ATM, so it handles workouts, showers, and casual swimming. Just skip saunas, very hot water, deep diving, and high-pressure jets so you don't stress the seals.

Will the app work on my phone?

The Evolu app is on its way to the App Store and Google Play. As soon as it's live, the download links will show up right here.

What does Evolu Coach do?

It answers knowing who you are: your sleep, your workouts, what you ate, your lab results, your limitations, and the conversations you've already had. It shows charts built from your own numbers and, if you ask, changes your plan. And it only says it's done after double-checking. It guides training and routine, but it doesn't replace a doctor or dietitian.

Can I train for a race or a specific goal?

Yes, with Personal challenge. Tell Coach the goal (your first half marathon, swimming 1 km, climbing a mountain) and the date, answer a few questions, and get a week-by-week plan to get you there, alongside your training or on its own. If the deadline is too ambitious for your level, the app tells you before you start.

I'm on Mounjaro, Ozempic, or another GLP-1. Can Evolu help?

It helps you keep everything organized: the app logs each dose and injection site, reminds you of the next one, and tracks your weight and how you feel during the week. Your doctor still prescribes and adjusts the dose.

What if I can't stick to my routine?

You don't go back to zero. Missed a workout, traveled, slept badly? Evolu reshuffles the next few days and your progress stays put. And if your diary has gaps, it asks what happened, no lecture, and uses your answer to understand the days that follow.

Are my data and photos safe?

Yes. Photos are encrypted on your phone before they're uploaded, and the key never leaves it. Lab results and documents are used only for your own tracking, and you can delete everything whenever you want.

Can I cancel anytime?

Yes. On the monthly plan, you can cancel renewal whenever you like. Annual plans stay active until the end of the paid period and won't renew after you cancel.
