Reminders help you get all your "to do's" done and dusted - and this will sync between your Mac and other iOS devices. You can make as many to-do lists as you need and add to them with ease.
Set due dates and you'll get alerts as deadlines approach. Check items off your lists as you go and keep track of what you've completed. And to be sure you don't forget anything, iCloud keeps your reminders up to date on your Mac, iPad, iPhone, and iPod touch.
Mail makes it easy to manage all your email from a single inbox. It features powerful search capabilities, with search suggestions and tokens built in. It works with the free me.com email account you get when you sign up for iCloud, as well as most email standards - including POP3 and IMAP - and popular email services such as Gmail, Sky, Virgin Media, Yahoo! Mail and Hotmail/Outlook. Mail also supports Microsoft Exchange 2010.
If you have more than one email account, no problem - add your accounts to Mail and you'll be able to access all your email from one place. Usings Conversations, messages from the same thread appear in an elegant timeline showing each communication as it was sent while hiding redundant text.
Contacts is a flexible and convenient place to store information for everyone you know. It's easy to import names, numbers, addresses and photos from other applications, and it's also designed to work with Facebook.
Contacts automatically includes your friends' profile photos and information, and when friends update their information Contacts updates your Mac.
You can create smart groups for clubs, activities, and business purposes or print address labels and envelopes. You can sync the data from Contacts via iCloud to your iPad, iPhone, iPod Touch, and Mac - so when you enter someone's contact info once, you have it everywhere. Contacts is built on vCard, an industry standard for storing contact information, your friends can send you cards that you can add simply by dropping them into your contacts list - no typing required.
Keep track of your busy schedule and share it with others using Calendar. Create separate calendars - one for home, another for school, a third for work, and so on. See all your calendars in a single window or choose to see only the calendars you want. Calendar lets you create invitations using information from Contacts, update your guest list, keep track of responses, and receive the latest status information.
When you or another Mac user receives a Calendar invitation via Mail, it's automatically added. Calendar also works with iCloud, Yahoo!, and Google. When you use iCloud, every Calendar edit you make on your Mac automatically appears on your iPad, iPhone and iPod Touch. So no dinner dates are missed, no meeting goes unattended, and no anniversary is forgotten.
TIP: A cool way to add an entry to your calendar, just type free text such as "Movie at 7pm on Friday" and it will work it out for you.
Notes is designed for whatever's on your mind. Jot down your thoughts. Add photos, images and attachments. You can add, delete and flip through your notes, or do a quick search. Use the Share button to send your notes with Mail or Messages. Pin important notes to your desktop so they're easy to get to. And take them with you everywhere.
Notes works with iCloud, so when you create or edit a note on your Mac, it automatically updates on your iPhone, iPad and iPod Touch. And vice versa.
SHOWHOW TIP: Notes is by no means a substitute for Word or other word processing applications. This is essentially a small jotter, ideal for things like shopping lists or quickly writing down ideas.
FaceTime for Mac makes it possible to video chat with anyone on an iPad, iPhone, iPod Touch, or another Mac. Just find who you want to see in Contacts and start a FaceTime call. When someone wants to reach you, the call rings through on every Mac or Apple device you own even if FaceTime isn't running.
FaceTime links directly into Messages, so if you're having a text conversation you can switch to voice quickly and easily.
Messages takes your conversations even further, because now you can send messages to anyone on an iPhone, iPad or iPod Touch running iOS 5 (or later). Messages appear on your Mac and any device you use, which means you can say hi from your Mac and keep chatting on your iPhone or iPad.
Send photos, videos, documents and contacts - even send messages to a group. You'll see when your message has been delivered and when someone's typing a reply. Turn on read receipts and they'll see when you've read a message. With end-to-end encryption, your messages stay safe and private.
