Question

Is there any stable nosql database for iOS except for Couchbase? Couchbase is now a beta version which i don't want to use on a app with many users.(Although i like Couchbase very much)

Any suggestions? Special Thx!

Answer 1

There are several projects to get a CouchDB-compatible API available on mobile devices.

• TouchDB, a native iOS build
• PouchDB, an HTML5 implementation, for web and PhoneGap apps

Answer 2

Edit (April, 2016):

• Realm.io is the way to go nowadays.

Also take a look to this Key/value databases that have been ported (wrapped) to iOS:

• LevelDB (Port: NULevelDB): Made by Google, and it seems to be one of the fastest out there.
• TokyoCabinet ( Port: TSDocDB): Very fast, but it seems to be a bit outdated, the official page states that there's a new version (called KyotoCabinet) that is even faster, but for that there's no port (as far as I know). And, is licensed as LGPL (that it seems not to be fully compatible with the AppStore).
