One-time purchase
Premium is something you buy once.
Oasis does not ask you to choose between a monthly plan and an annual one. The free version remains usable for as long as you want, with three nature sounds, the mixer, two background noises, Delta binaural mode, two timers, and two ready-made soundscapes. Premium is a single in-app purchase that unlocks the rest of the library, along with future Premium sounds.
A free version you can keep using
Without paying, you can mix birds, wind, and beach sounds, adjust their volume and position, use white and brown noise, listen with Delta mode, choose 15- or 30-minute timers, and play two Oasis soundscapes. Short previews also let you sample selected Premium content.
What Premium unlocks
Premium adds the other 32 nature sounds, pink and green noise, fan and airplane cabin sounds, Theta, Alpha and Beta modes, 1- and 2-hour timers, the remaining Oasis soundscapes, and the ability to create and save your own mixes.
Future Premium sounds are included
Once you own Premium, new sounds added to the Premium library become available without another purchase or recurring payment.
Restore Premium with the same Apple Account
On another iPhone, open the Premium screen and restore your purchase using the Apple Account that originally bought it. Your Premium access can be restored, but custom soundscapes remain on the device where they were created.
