Breathe.
A voice-controlled breathing game that helps you find calm through your own exhale.
Try it first. Then read about how it works.
Anxiety is everywhere, and most tools don't meet you where you are.
Around 301 million people worldwide live with an anxiety disorder, and far more of us move through everyday moments of it without naming it.
Most of the tools built to help feel clinical, heavy, or prescriptive. You open them when you are already overwhelmed, and the first thing they ask is something hard. The help is real, but the door is small.
What if a breathing exercise felt like a game?
Breathing exercises already work — they are one of the most studied, lowest-effort interventions we have. The gap is in how they feel. So I gamified one. You exhale into your microphone, and a small blob rides your breath along a sine wave. No forms, no score to beat, just your breath and the curve.
Breathe. is the first in the Mindgrid series — a set of playful tools exploring mental health through interaction rather than instruction.
Your voice moves the blob.
The mechanic is inspired by Flappy Bird, but inverted — instead of tapping to fight gravity, you breathe with it. Inhale and the blob rises. Exhale, audibly, into your mic and it falls. The target path is a sine wave tuned to a breathing rhythm, so staying on the line means you are already pacing your breath.
Four modes tune the rhythm to how you feel:
Calm
3s in · 4s out · ~8.6 bpm
A resting pace for grounding and quiet focus.
Hiking
3s in · 3s out · ~10 bpm
A 1:1 cadence for sustained walking and uphill stamina.
Cycling
2s in · 3s out · ~12 bpm
A 2:3 ratio that matches pedal cadence and steady output.
Custom
You pick in / out · Your rhythm
Set your own inhale and exhale with the slider.
Gamifying breathing.
A short walk-through of the session flow, from picking a mode to riding the curve with your own exhale.
Slow exhales tell your body it's safe.
A long, deep exhale activates the parasympathetic nervous system — the brake pedal of your body. Heart rate slows, cortisol drops, and the fight-or-flight signal eases off.
That is what the game is quietly doing. Every time your exhale carries the blob down the curve, you are nudging your body out of alert and back toward rest. The calm is not imagined. It is physiology.
What I took from building Breathe.
- Designing for emotional states is a different craft. Every word, every color, every timing curve either settles someone or pushes them further from the feeling you are after.
- Constraint can be kindness. Stripping away scores, streaks, and progress bars meant the tool could not accidentally become another thing to fail at.
- AI-assisted coding with Claude Code let me move from rough idea to a working, tuned prototype quickly — so most of the time went into the parts that actually matter: feel, pacing, and tone.
