A quiet breathing companion for Android. Pick a rhythm, follow the glow, and let everything slow down.
No ads · No accounts · No internet · Nothing tracked.
Sylph never connects to the internet. Every technique, theme and sound lives inside the app — nothing streams, nothing phones home, nothing is collected. No streaks, no history, no accounts, ever.
The only networked component is Google Play's own billing client, used solely if you buy Sylph Pro. Read the whole privacy story →
Pick a rhythm and go — no signup, no trial, no nag screens.
Even and steady — four sides, one rhythm.
A long, unhurried out-breath to wind down.
Five and a half seconds in, five and a half out.
Short in, long slow out.
Brisk and bright — a quick lift for a slow morning.
Long, soft out-breaths to slow down before sleep.
Long holds for practiced slow-breathers.
An unhurried, even rhythm — six in, six out.
Ease off the day with a short in and a long letting-go.
A gentle, wakeful start.
Slow everything down and settle.
A custom pattern builder with six saved slots.
A soft glow that rises and falls with your breath. Five visual themes and eight orb colours, from a simple orb to layered curtains and warm lantern light.
Gentle haptic pulses swell and fade in time with each breath — on by default, four themes to choose from.
An optional tone that swells and settles with you. Off by default; four themes when you want it.
One purchase on Google Play. Restores on any of your devices. That's the whole business model — no ads to show you, no data to sell.
Direct download, signed by us. Android 8.0+. Your phone will ask you to allow installs from your browser — that's Android's standard flow for apps outside the Play Store. The Play listing is rolling out now; purchases of Sylph Pro go through Google Play.
