02 / The software

Guidance that listens
to your breathing.

Prana connects a breathing exercise to the person doing it. Sensor feedback makes each inhale, exhale, and pause part of the experience—and part of the session record.

Existing Prana iOS app

Three ways to train and track.

The existing iOS platform brings together an extensive exercise library, sensor feedback, and session analytics.

Visual training

Breathing controls an interactive experience. The bird rises with an inhale and descends with an exhale.

Haptic training

Vibration cues guide inhalation, exhalation, and holds, with feedback when breathing departs from the target pattern.

Passive tracking

Monitor breathing patterns to detect stress patterns and get notification warnings. Optional posture feedback can accompany passive tracking while resting or working at a desk.

Custom patternsAdapt practice to a chosen protocol
More about the platform’s capabilities

Beyond respiration rate

The software tracks inhalation and exhalation timing, pauses, breath consistency, and the relationship between the actual breathing pattern and the exercise target.

Posture as a companion signal

Breathing and posture can be trained together or separately. Placement on the lower back or upper torso supports different training goals.

Additional measurement potential

The original retractable platform also supports body-circumference measurements and history, extending the utility of its hardware architecture.

Breath-driven interaction

Your breath
becomes the controller.

Inhale to rise. Exhale to descend. Follow a trail of flowers through a quiet garden, with the path expressing the breathing pattern.

The existing Prana platform already uses breath-controlled gameplay. This 3D concept explores the next generation of that experience.

The advantages of a retractable form factor.

A compact, self-contained pod

No bulky belt strap. The thin belt retracts into the device, ready for the next session.

Wear it with your own clothing

Quickly wear it over or under clothing, without clipping to a tight waistband or needing a special shirt.

No buckles to adjust

The retractable belt extends to fit the torso. Connect the clip and lock the belt at the chosen fit.

Attach without adhesives

No adhesive patches, replacement tape, or shaving needed. Put it on and take it off within a few seconds for each session.

04 / Applications

Unlock the power of
breathing exercises.

Prana brings real-time guidance and feedback to breathing exercises, helping people follow the practice and researchers review adherence.

Clinical research & home protocols

A search for breathing exercises on ClinicalTrials.gov returns over 5,000 study records . Prana helps make participant adherence visible through sensor feedback and shareable session data.

Illustrative clinical-study setting · Next-generation device

Guide the session.
Capture adherence.

  • Help participants follow the protocol.

    Haptic and visual cues guide your breathing practice, including sessions completed independently at home.

  • Record what happens breath by breath.

    Track breathing patterns, adherence to the exercise, and posture when relevant to the study.

  • Share session data.

    Export records for review and analysis.

Potential medical & research applications

  • COPD & pulmonary rehabilitation protocols
  • Asthma & breathing-retraining studies
  • Breathing guidance within HRV biofeedback
  • Anxiety & stress-related breathing research
  • High blood pressure & slow-breathing studies
  • Yoga-breathing research after spinal cord injury

These are potential uses for breathing guidance and adherence tracking, not demonstrated treatment outcomes for Prana.

Consumer wellness & digital experiences

A breathing practice
that fits daily life.

Live feedback gives people a way to follow a breathing pattern and see their progress, while feeling more engaged. For wellness apps and wearable ecosystems, that opens up experiences built around:

  • Stress reduction & relaxation routines
  • Sleep preparation & evening wind-down
  • Focus & mindful attention
  • Meditation & breath-controlled play

Screen-free breathing guidance

Wear it over
everyday clothing.

A compact pod and thin belt make it easy to begin a session at home or during a break. Haptic cues support quiet practice without watching a screen.

Designed for use at rest: sitting, standing, or lying down. Posture training depends on placement and position.

A closer look at the hardware and app

The science behind guided breathing.

Breathing exercises depend on timing, movement, and consistency. Prana makes those elements visible with live feedback and session records, helping people practice and researchers review adherence.

Explore breathing science and research

Research looks beyond breaths per minute to examine how breathing patterns, abdominal movement, and posture relate to physiology and wellbeing.

Breathing rhythm

Inhale and exhale duration, pauses, and their ratios shape a breathing pattern. Research has compared slow breathing rhythms and their effects on heart rate variability and relaxation.

Slow breathing & HRV study

Abdominal movement

Movement of the abdominal wall helps make diaphragmatic breathing visible. A randomized study examined diaphragmatic breathing training in relation to attention, emotional state, and cortisol.

Diaphragmatic breathing study

Posture & breathing

Body position is another part of the breathing context. A study in people with COPD examined how breathing technique and posture affected lung volumes and ventilation.

Posture & breathing study

These studies explore breathing practices and physiology; they do not evaluate the Prana device.
