How can we help?

What's the difference between white, pink, and brown noise?

White noise has equal energy across all frequencies—crisp and hissy, ideal for focus. Pink noise decreases energy at higher frequencies—warmer and more natural, best for sleep. Brown noise has even more bass—deep and rumbling, perfect for relaxation and meditation.

How do I play a sound?

From the Counter screen, tap the droplet icon to start playing. Tap again to pause. Long-press the icon to stop completely. You can also select different sounds from the Dispensary tab.

How do I change the timer duration?

On the Counter screen, tap the time display to choose from preset durations: 15 minutes, 30 minutes, 1 hour, 2 hours, or 8 hours for overnight use.

What does the strength slider do?

The strength slider (from Gentle to Potent) controls the volume of the sound. A safety indicator shows when volume levels may affect hearing with extended use.

Will the sound play with my screen off?

Yes. Tonic continues playing in the background when you lock your device or switch to other apps. Use the lock screen controls to pause or stop playback.

What is the consultation quiz?

When you first open Tonic, you can take a brief 5-question quiz about your sleep and focus needs. Based on your answers, Tonic recommends an ideal sound, volume, and duration. You can retake this quiz anytime from Lab Notes.

Can I skip the consultation?

Yes. During onboarding, you can skip the consultation and go straight to using the app with default settings. You can always take the quiz later from Lab Notes.

Does Tonic work offline?

Yes. Tonic works completely offline. All sounds are generated on your device or bundled with the app. No internet connection is ever required.

How do I reset the app?

Go to Lab Notes and tap "Reset All Data" to clear all saved preferences and start fresh. This will also reset your consultation results.
