Why choose a one-time payment sleep app?
A one-time payment sleep app like Zenbird saves you money in the long run. While competitors charge $50-$100+ per year in subscriptions, we believe that investing in your rest shouldn't feel like paying rent.
With Zenbird, you can download the app for free and enjoy our essential sound library at zero cost. If you ever want the ultimate experience, we offer a single payment of $14.99 for lifetime access to Zenbird Pro. No hidden fees, no auto-renewals, and no "forgot to cancel" surprises on your credit card.
What sounds are included for free?
Start relaxing immediately with our generous free tier—no account required. Zenbird offers 3 essential high-quality nature sounds completely free:
- Midnight Shower: Soft rain on a forest canopy, perfect for 3am stillness.
- King Nightingale: A nocturnal songbird optimized specifically for deep sleep.
- Morning Orchard Canary: A refreshing dawn chorus from tropical fruit groves.
Free users also get unlimited access to the sleep timer, 4-channel sound mixing, and focus timer features (supported by unobtrusive banner ads).
How does the 3D Spatial Studio work?
Available exclusively for Pro users, Zenbird's 3D Spatial Studio uses advanced audio engineering to create an immersive 360° soundscape tailored exactly to your liking.
Users can layer up to four different nature sounds simultaneously. More than just adjusting the volume, you can literally drag and position multiple sound nodes around you in a virtual space. Want the crackling campfire to your left and a babbling brook behind you? You can easily set it up.
When using headphones, this spatial arrangement tricks your brain into feeling entirely surrounded by nature, making it the most powerful tool for deep sleep or intense focus.
