At it's very core, Simplenote relies on a library called Simperium (http://github.com/Simperium/simperium-ios/ http://github.com/Simperium/simperium-ios/). In the past few months / years, we've significantly improved both, it's performance and reliability. Sync'ing bugs are taken very seriously, if you ever experience any kind of glitch, please: just let us know. We'd be thrilled to have you back with us!
