Waarom niet gewoon een app of een andere tool zoals Moonbird gebruiken?

In tegenstelling tot traditionele tools die fysiek bewegen of eenzijdig werken, maken de Pebbles gebruik van bilaterale haptiek in beide handen. Dit kalmeert je zenuwstelsel op een natuurlijke manier zonder mechanisch geluid of afleidende bewegingen.

Wat meten de Pebbles precies (en waarom is dit uniek)?

De Pebbles meten je hartslagvariabiliteit (HRV) via een ingebouwde PPG-sensor. Waar veel andere ademhulpmiddelen alleen een vast ritme opleggen, laten de Pebbles je zien of de oefening ook echt effect heeft op je lichaam.

Hoe vaak moet ik de Pebbles gebruiken voor resultaat?

Voor een direct kalmerend effect volstaat een sessie van 10 minuten. Dankzij het discrete en stille ontwerp kun je de Pebbles overal gebruiken, van kantoor tot de trein.

Hoe zit het met de veiligheid van mijn data?

Alle bio-sensor gegevens worden anoniem verwerkt en veilig opgeslagen. Jouw data is van jou en wordt uitsluitend gebruikt om je gepersonaliseerd inzicht te geven in je mentale gezondheid.

Glimp | Pebbles - the smart breathing coach in your palm

Why rest goes beyond just following a movement.

Many breathing tools use mechanical movements to control your rhythm. The Pebbles work differently. By using bilateral haptic signals — soft, rhythmic vibrations in both palms — they help to slow down your nervous system in a natural way.

This method provides deeper focus and a sense of “grounding” without being distracted by moving parts or striking sounds. The vibrations are whisper-quiet and subtle; you can feel them exactly where you need to relax.

While holding the Pebbles, the built-in PPG sensor measures your heart rate variability (HRV). This gives you immediate insight into your recovery, based on facts, not feelings. No distractions. No hassle. Just the essence of rest.

How the Pebbles Help You

Designed for a brain that is already full enough.

It's really easy.

You simply hold the Pebbles in both hands and let the subtle vibrations do the work. Inhale on the left, exhale on the right. No mechanical pressure or coercive movements, but a natural cadence that naturally slows your breathing to a steady pace.

This form of rhythmic accompaniment requires less conscious attention from your brain. Where other methods require active focus, the Pebbles allow your nervous system to calm down through pure sensation. This is more effective in case of overstimulation: you don't have to 'follow' anything, you just have to hold on. You come back into your body and out of your head.

I want to try the Pebbles

More than an app, more than mindfulness.

The Pebbles are your silent partner in a world full of incentives.

You may have tried several things to relax: apps, breathing exercises on YouTube, meditation at bedtime. It often works for a while, but the routine disappears again. The reason? It is difficult to build into a busy life. You're tired, forget it, or drop out of the umpteenth notification.

With the Pebbles, this is a thing of the past.

An anchor that fits everywhere.

The Pebbles are small, stylish and discreet. Place them on your desk or nightstand as a visual reminder. Unlike larger tools, they literally fit in your pocket, so you can work on your rest unobtrusively anywhere.

100% Screen-Free, 100% Focus.

You can't find peace on a screen. Thanks to offline mode, you don't need a phone to start a session. No notifications, no blue light, no distractions. Pick up the Pebbles and start right away, wherever you are.

Feel the cadence, forget the technique.

Where other aids work with mechanical movements, the Pebbles use subtle haptics. These natural vibrations guide your breathing without making it feel compelling. There's no need to watch or anticipate; your nervous system responds intuitively.

Insight through biofeedback.

Rest is no longer a gamble. During your exercise, the Pebbles measure your heart rate variability (HRV) via a built-in PPG sensor. This way, you can see proof of your recovery in the app after each session. Science in the palm of your hand.

Why the Pebbles are different

Going beyond just a rhythm.

Real rest requires more than just a rhythm. From balance in both palms to measurable HRV insight, find out why details make a difference.

4.7 out of 5

on Trustpilot

“The Pebbles are really nice. My biggest measure of success? I fall asleep every time I do a 15-minute session, which is a sign of (very) deep relaxation. The vibration is easy to feel — not too much, but certainly not too little — and is extra relaxing in addition to the natural rest that calm breathing gives you.

The big plus is the guidance via vibration instead of mechanical movement. This is an essential difference with tools such as the Moonbird, which lag a bit behind in terms of tactile guidance because they feel more mechanical and are less tactile. Plus, you have the Pebbles in both hands, which makes for a much more pleasant and complete sense of calm.”

Insight

Make your recovery visible: more than just a rhythm.

Get even more out of your breathing sessions with the Pebbles thanks to the unique bio-sensor and the Glimp app. The Pebbles are easy to connect to the app and give you insight into your results. But you'll also find many great guided sessions in the app that are linked to your Pebbles.

The coach who listens to you.

Where other tools only set a rhythm for you, the Pebbles listen to your body. The built-in bio-sensor measures your heart rate variability (HRV) in real time. This way, you can be sure that the exercise actually has an effect on your nervous system.

No guesswork, just hard facts.

After each session, you can immediately see the result in the Glimp app. You see your stress levels drop and your HRV rise. No vague promises about relaxation, but scientific data that proves that you are back in balance.

Scientific protocols for every purpose.

Whether you want to focus, fall asleep faster or calm a panic attack, our app offers programs developed by breathing experts. Always tailored to your personal bio data from the Pebbles.

Science in the palm of your hand:
restore that you can measure.

“Your stress regulation is not determined by how well you relax on vacation, but by how quickly you recover between efforts in your daily life.”

— neuroscientist Dr. Andrew Huberman
‍

Real resilience comes from a nervous system that is trained to switch quickly. Where many tools are limited to providing a rhythm, the Pebbles go one step further through this process measurable to make.

By using subtle haptic signals, your parasympathetic nervous system is directly addressed — the part of your body that is responsible for rest and recovery. But we don't just leave it with a feeling. Thanks to the built-in PPG sensor, the Pebbles measure your heart rate variability (HRV), the most reliable measure of stress.

The result? Not only are you training your breathing, you're training your ability to release stress. That is breathwork with today's precision.

Pebbles: a breath of fresh air up close

As a breath coach, I use Pebbles to support the exercises at home. It also encourages regular exercise. It's more than “sitting and breathing”. You always have two breath coaches at hand!

It's very easy and intuitive

“It's really easy and intuitive to follow the vibrations! For me, it works better than counting in your head, like you have to do with most meditation apps. And it's nice to have NO screens or apps around you for once.”

Everyday tool for effortless breathing rest

I use the Glimp Pebbles almost every day, both for myself and my husband. But certainly also in my practice as a respiratory physiologist. What makes the biggest difference for me is that I don't have to count anymore. Vibration guidance feels much more natural and calming than hard beats or timers. All you have to do is feel. I can lie down with my eyes closed and stay fully engaged while the Pebbles set the rhythm. The options for setting the breathing exercises are very versatile, a suitable exercise for everyone at the moment. This works great for me and my clients. The Pebbles are a simple but incredibly effective tool that really deepens my breathing training.

From overstimulated with your pebbles back to normal within fifteen minutes...

I bought these because I was easily overstimulated. And then had to go to bed with medication to recover. For example, after shopping. Now, when I get home, I'll grab the pebbles. And within fifteen minutes, I will be able to function again. I think it's a special breathing tool. It shows nicely through the vibration when you need to put in or out. Regular relaxation exercises or meditation. Never achieved this result.

You can do a lot of different breathing exercises and modify them if you want it a little different. And you can use your Pebble offline. Nice breathing tool.

I've been using Glimp and the Pebbles since June 2024 and it helps me do breathing exercises almost daily. I wouldn't want to miss them anymore. What I've found very helpful and stimulating lately are Kim Padding's sessions. Lovely to let me take you along!

Great tool for my breathing sessions. Almost 1000 sessions participated now. Pebbles from Glimp also continues to develop based on feedback from the field! Definitely recommended, so I'm less in my head, counting less.

Excellent service and a tool that truly works

I was pleasantly surprised that my Pebbles breathing tool was repaired free of charge—it turned out to be covered by the warranty. The repair was quick, and I received it back in no time. I personally find Pebbles more comfortable than Moonbird. It fits better in the hand, and the difference between inhaling and exhaling is clearer because you hold a Pebble in each hand. Moonbird is also a good tool, but Pebbles works better for me. Highly recommended!

Frequently asked questions

Why not just use an app or another tool?

An app on your phone often distracts you in the form of notifications or blue light. The Pebbles offer a completely screen-free anchor. Unlike traditional tools that move physically or work unilaterally, the Pebbles use bilateral haptics. By sending gentle vibrations into both palms, you calm your nervous system naturally and intuitively. So you don't have to 'watch' or 'follow', but you can simply 'feel'.

What exactly do the Pebbles measure (and why is this unique)?

The Pebbles are more than just a guide; they are a measurement system for your rest. Thanks to the built-in PPG sensor we measure your heart rate variability (HRV) during the session. Where many other breathing aids only set a fixed rhythm, the Pebbles show you whether the exercise actually has an effect on your body. This is how you make recovery tangible and scientifically substantiated.

How often do I have to use the Pebbles for results?

For an immediate calming effect, a 10-minute session is sufficient. For a lasting change in your nervous system and higher resilience, we recommend using the Pebbles daily. Because the Pebbles are discreet and quiet, they fit effortlessly into your routine: in the office, on the train, or before bed. Building a healthy habit has never been so easy.

What about the security of my data?

Your mental well-being is a private matter. All data from the bio-sensor is processed anonymously and stored securely. We only collect data to give you insight into your own progress and to offer you personalized breathing exercises. Your data is yours and is never shared with third parties.

Peace that you don't have to follow, but can feel.
