The Once app allows you to chat and get acquainted for free. Once every 24 hours, each participant will have a match with another participant, and if both “like” each other, they can chat without restrictions. If one match per day is not enough, or you want to use advanced features, there is a premium membership. The pricing policy is about the same as competitors. Traditionally there are discounts for longer subscriptions. You can also buy special currency called “crowns” to access additional features.
