Crest: Breathe & Calm

Crest is a calm breathing app where you watch your breath like an ocean wave. The water rises — breathe in. The water falls — breathe out. That's all. Why Crest is different: - No ads. Your attention is yours, not for sale. - No levels, scores or badges. Not to compete — to calm down. - Local-first. No account required; all your data stays on your device. - Honest metrics: calm minutes, longest exhale, consistency. What's inside: - Personalized calibration: it measures your natural exhale and tunes the rhythm to you. - Four channels — Calm, Sleep, Focus, Energy — each with its own breathing rhythm. - Start when you're ready: tap, count down, then breathe with the wave. - Gentle haptic feedback and a flowing water animation. - Ocean (day) and Night themes, switching automatically. - Turkish and English. - One gentle daily reminder (optional). Crest is made to slow down, ease tension and wind down for sleep. Quiet, measured, at your own pace.
