Hi anaranjador
Unfortunately notes, including handwriting, do not sync as this is limted only to calendar entries and tasks. The app can sync using ical so syncing between iPhone and iPad is possible. I myself have not used this function as I only have an iPad and no iPhone. I do have an android phone which is why Google sync works for me.
This is the main outline of features:
Organizer is a productivity app for the iPhone and iPod Touch, while Organizer HD is its larger iPad counterpart. Although “Google Calendar™ support” is mentioned, both these apps sync seamlessly with iCal. Not all calendar apps offer iCal syncing, however. This spells a big win for Organizer.
Of course, due to the iPad’s larger screen area, Organizer HD is much more enjoyable to work with than its smaller cousin, especially since you can use it in landscape mode. Small differences aside, both apps offer similar features and are extremely easy to use. A single tap on the screen will reveal a navigation menu, while tapping the screen twice will display the editing menu. Several tools will enable you to insert text, events, maps, pictures, smilies and other emojis, draw lines or shapes in various colors, and include contact details from your address book. Additionally, you can make and play voice memos. There are also editing functions that will let you cut, paste, zoom, and rotate objects.
Organizer HD allows you to view your calendar by day, week, month, or as a list. More options are accessible outside the app, under your device Settings. You can customize the look of your organizer by selecting your choice of paper color and size, as well as design (lines, grid, or blank paper). One useful function allows you to roll over unfinished to-dos. And if privacy is a concern, you can activate a password lock. There’s a whole host of other options. For instance, those who are addicted to tweeting can enable Twitter integration. Google Calendar and iCal import options are also available within these settings.
Even though I have had Organizer HD for a few weeks I still haven't used all of it's functions. Those I have used work perfectly.
