  • More than an app

    We know it’s hard to make a routine from using an app. We’re offering a tangible way, to work on your mental health.

  • More than mindfulness

    We know it’s hard to really notice anything from your mindfulness practice. Breathing is the most effective way to reduce stress in your body.

  • More than therapy

    We know it’s hard to apply the ‘thinking techniques’ you’ve learned in therapy, in real life. Learn to listen to your body, the Pebbles are always there for you.

Guided breathing through intuitive vibrations

Our science-based breathing exercises follow specific breathing rhythms. Just follow the vibrations, the rest is intuition. The vibrations will distract your wandering mind and help you to truly focus on your breathing to immerse yourself in the exercise.

Grip on your mental health

Through our unique bio-sensor, the app will give you insight in your overall mental health. Biomarkers like Heart Rate Variability (HRV), Oxygen Saturation (SpO2) and Skin Temperature  will help us to determine your personal wellbeing score.

Restore your resilience

Research shows that breathing exercises are the most effective way to train your stress-resilience. Feeling overwhelmed? Breath training helps to deal with high workload, it enhances cognitive function and positive thought (Zelano, 2016).

Build a healthy habit

The Pebbles will form a physical reminder to help you ‘catch your breath’ on a daily basis. This will prevent chronic stress from building up over time.
