Prana Labs Inc.

Vayu is a breathing and wellbeing app developed by Prana Labs, founded by Dhruv Adhia and Deepali Raiththa. It helps people practise guided breathing through gentle wrist taps on Apple Watch and Wear OS, so sessions can be followed with eyes closed and without audio or a screen. The app uses smartwatch signals, including heart rate, sleep and heart rate variability (HRV), to inform breathing guidance and help users explore their responses over time. Its tools include session tracking, a journal, mood check-ins and analytics that make patterns across practice and physiology easier to understand.

Vayu offers breathing techniques such as box breathing, resonance-frequency breathing, 4-7-8 breathing, cyclic sighing and custom breath ratios, alongside pranayama practices including Bhastrika, Kapalabhati and Anulom Vilom. Users can start with a free guided session and basic tracking. A paid Pro subscription adds unlimited sessions, a broader library of breathing and reset practices, and longer-term physiology insights. Available for iOS and Android, Vayu supports Apple Watch and Wear OS devices.
