Discover Your Breath. Find Your Rhythm.

Ondine is a modern breathing and mindfulness app designed to help you develop conscious breathing habits, track your breathing capacity, and support your daily well-being routine.

It brings together science-based breathing techniques, BOLT tracking, daily breathing protocols, and progress statistics in a simple, distraction-free experience.

Breathe more consciously. See your progress. Stay in control of your data.

Breathing Is More Than a Reflex

We breathe thousands of times throughout the day, yet we are often unaware of how we breathe.

Ondine was developed to help you make breathing a conscious part of your daily life. Through structured exercises and visual guidance, you can practice different breathing techniques at your own pace.

The goal is not simply to complete a few minutes of exercise, but to build more sustainable breathing awareness.

What Can You Do with Ondine?

🌬️ Guided Breathing Exercises

Follow the inhalation, breath-hold, and exhalation phases visually.

Ondine provides a simple, focused session experience that helps you maintain your breathing rhythm.

🫁 Different Breathing Techniques

Explore breathing techniques designed for different purposes and incorporate the methods that suit you into your daily routine.

Each technique is structured so that it can be followed step by step.

⏱️ BOLT Tracking

Record your BOLT scores to observe changes in your breathing control and track your progress over time.

Consistency matters more than a single measurement. Ondine helps you review your previous results and evaluate your personal progress.

📅 Daily Protocols

Incorporating breathing exercises into daily life can sometimes be challenging.

The daily breathing protocols in Ondine help you create a more consistent structure by guiding you on which exercises to practice and when.

You can start with short sessions and gradually develop your breathing practice over time.

📊 See Your Progress

Track your completed sessions, breathing exercises, and changes in your performance.

Ondine’s statistics and progress screens help you not only feel your breathing practice, but also see your consistency over time.

Small steps. Regular practice. Visible progress.

🙂 Record Your Session Experience

The duration of a breathing exercise is not the only thing that matters; how you feel after the session is important too.

Ondine helps you evaluate your session experience and mood, allowing you to follow your personal breathing routine more closely.

🫁 Visual Breathing Guidance

Visual elements, breathing phases, and anatomical visualizations are used to make it easier to follow your rhythm during breathing exercises.

This allows you to focus on your breath instead of constantly reading the screen.

Health Connect Integration

Use it with the Android health ecosystem if you choose.

Ondine optionally supports Health Connect integration.

If you grant permission, eligible completed breathing and mindfulness sessions may be saved to Health Connect.

Health Connect is not required, and you can review or revoke the necessary permissions at any time through your Android settings.

Privacy Comes First

Your breath belongs to you. So does your data.

Ondine is designed with an offline-first approach.

You do not need to create a QuantoriaLabs account to use Ondine.

Simplicity. Focus. Awareness.

One idea lies at the center of Ondine’s design approach:

Technology should not come before your breath; it should help you focus on it.

That is why the app combines a simple interface, visual breathing guidance, daily protocols, personal progress tracking, and a privacy-focused data approach in one experience.
