My Notational Velocity currently has 748 notes in it: song lists, research material, bits of computer code and so on. I find it handy to have 2 separate Notes apps.

This is a beautiful combination and superior to Notes in many ways. For more info see here. Use Notational Velocity (on the Mac) synced with Simplenote (iOS). Use Notes app on your iPhone and computer – they sync with iCloud. If you want to share outside of the Apple ecosystem (eg to an Android phone like Google or Samsung) read this article. Use built in Calendar app on your iPhone and OSX, and sync via iCloud. If you have an Android phone read this article on how to sync iCloud with Google Contacts. This will keep you iPhone and computer in sync. Use Apple built in Address book (OSX) and Contacts (iOS) and they sync over iCloud. If you have an Android Phone read this article instead. Here’s my suggestions as to the best solution for each area that needs syncing. There are a number of ways to synchronise different kinds of information. If you have an iPhone, iPad or iPod touch you’ll want the latest information available on each one.
