We’re excited to share the very first playtest release of Aerius, our anxiety support and breathing exercise app. 

In playtest:

• Quick Calm Button — a one-tap breathing exercise with animations.

• Breathing Library — includes:

  • Box Breathing (4-4-4-4)

  • 4-6-8 Breathing

  • Resonant Breathing (5s inhale/5s exhale)

  • 5-4-3-2-1 Grounding Exercise

• Animations & Visuals — expanding/contracting circles guide you through the rhythm.

• Voice & Text Prompts — text instructions and optional voice guidance.

• Offline Support — works fully without an internet connection.

• Emergency Button — quick access to resources if you need urgent help.

Goals 

• Do the breathing exercises feel natural and calming?

• Is the interface easy to understand?

• Are the timings right, or do they need adjustment?

• What accessibility improvements can we make?

What’s Upcoming?

• Add session history and streaks.

• Support favorites and shortcuts for quick access.

• Include progressive muscle relaxation.

• Polish accessibility (larger fonts, high contrast, haptics options).

How to be involved?

• Try the app for a few days when you feel anxious or want to relax.

• Send feedback about the exercises, the design, and any bugs you notice.

• Suggest new features or techniques you’d like to see.

Thank you for being part of our first step. Your input will help us make Aerius a genuinely useful companion for anxiety and stress relief,

Kind Regards,
