Couchbase Lite is an embedded JSON database with sync capability. It's Apache licensed and available for iOS and Android: https://github.com/couchbase/couchbase-lite-ios https://github.com/couchbase/couchbase-lite-android

We've been working on sync for a number of years, and have created an open-source lightweight iOS library and backend server. It's still alpha, but it's already in use by a handful of apps in the App Store. Here's an overview: https://github.com/couchbase/mobile The iOS embedded sync database: https://github.com/couchbase/couchbase-lite-ios Embedded sync database for Android: https://github.com/couchbase/couchbase-lite-android It is designed to sync JSON documents either to the cloud, or from device to device. Everything is open source, so you can run it wherever you want. Our conflict detection and management works by detecting when two users modify the same document, and keeping both versions around. It's up to the application to merge them (or discard one). More about the protocol here: https://github.com/couchbase/couchbase-lite-ios/w

There are a lot of alternatives to iCloud. Most of them are just backend-as-a-service, but some of them are really sync engines. Dropbox has been around a long time, and is really popular for iOS file sync. My team at Couchbase has been building mobile NoSQL databases that sync[1], for a number of years now, and our tech is used by a few apps in the app store already.[2] This preamble is to say that I've had plenty of conversations with developers who would be in iCloud's target market but decided not to use it. And the big reason they won't use it has very little to do with the reliability and user experience problems that keep coming up in the critiques of iCloud. The big reason they don't use it, is that they need to control their data. It's one thing for a small game or journaling app to outsource data management to Apple, but an enti

The TouchDB project was started at Couchbase, and since then we have ramped up our investment in mobile sync. The key thing about this project is that its designed to be tiny and boot fast. So it is written in Objective-C (and Java for Android.) We are renaming TouchDB to Couchbase Lite (still 100% open source), and have a bunch more tools for it: Couchbase Lite container for PhoneGap: https://github.com/couchbaselabs/LiteGap Couchbase Lite for iOS: https://github.com/couchbase/couchbase-lite-ios Community mailing list: https://groups.google.com/forum/#!forum/mobile-couchbase We are 100% serious about building the best damn database for mobile. Bonus points that it will seamlessly interact with other projects like PouchDB and friends via the sync protocol originally written as part of Apache CouchDB.

Important topic. Here is an in depth look at touch vs click, how to sprite images, etc http://maxogden.com/fast-webview-applications.html Also I think local data and avoiding network round trips is key to reliable consistent high performance. This is why we built Couchbase Lite for mobile. https://github.com/couchbase/couchbase-lite-ios
