A session paused when I switched apps

That's by design. Sylph has no background service and no notification. When you leave the app mid-session, it pauses and waits for you. Come back and tap to resume; it re-syncs with a short countdown so your breathing starts fresh on the inhale.

I don't feel anything / I don't hear anything

Haptics are on by default; sound is off by default. Both can be toggled from the session screen or from Settings. If your device has no vibration motor, the haptics toggle won't appear. If your device's motor doesn't support variable strength, Sylph falls back to a rhythm made of pulse timing instead of pulse strength.

I bought Pro and it shows locked

Open Sylph, go to Settings and tap Restore purchases, while signed into the store account that bought it: the Google account on Android, the Apple Account on iPhone. Pro is a one-time purchase tied to that store account, not to a device.

iPhone asks whether Sylph may find devices on your local network

Allow it. That is how Sylph finds your Chromecast, and casting will not work without it. If you said no, turn it back on in iOS Settings under Sylph.

Why does a free session stop at 5 minutes?

Sessions up to 5 minutes are free forever. Sylph Pro unlocks 10-minute sessions and an open-ended "until I stop" length, along with every technique, theme and the custom pattern builder.

How do I get Sylph?

Sylph is on Google Play in Early Access. No invites, no waiting list. Install it straight from the Google Play listing, or tap the Google Play badge on our Early Access page. Anyone who joined earlier keeps receiving new builds as usual.

Feature ideas

Send them in. Sylph stays small and private, but the technique and theme library will keep growing (Pro includes everything we ever add).
