Better than Apple’s Reminder app.
I’m one of those people who can’t remember anything unless it’s written down somewhere. (Indeed, I often consult my books to remember how to do something I actually wrote about!) So it should come as no surprise that I lean heavily on my Mac and iOS devices for a to do list or reminders.
Until recently, Apple did not provide any app that synchronized reminder items between iCal on a Mac and the iOS calendar apps. Not content to wait until they added such functionality, I tried two different reminder applications. The one I settled on — and still use daily today — is called 2Do by Guided Ways Technologies Ltd.
Right from the get-go, 2Do enabled me to synchronize reminder items between iCal and the 2Do app on my iPad and iPhone. It did this through MobileMe, which was very convenient. (2Do now supports iCloud, too.) I could create reminder items on any device, synchronize, and see the items on every device. I could also change or mark an item as complete on one device, synchronize, and have the item change or be marked complete on all devices.
In this example, I’m viewing 2Do’s reminder items in my “Air” calendar on my iPad. The grouping is customizable.
What I like a lot about 2Do is that it offers a wide range of fields that you can use to enter information about a reminder item. So not only can I add an item title, description, calendar, and other iCal-supported information, but I can also add fields for a start date, location, recurrence, tags, audio note, and pictures. I can customize the item entry form to include only the fields I use most in the order in which I want them to appear; I can access other fields with a tap. With the location features, you don’t need Siri on an iPhone 4S to take advantage of location-based reminders.
2Do supports three kinds of reminder items: ToDo, Checklist, and Project. A ToDo is a standard reminder. A Checklist is a reminder that includes individual checkable items. A Project is a reminder that includes individual ToDo items. Although I mostly use simple ToDos, Checklists and Projects are especially handy for grouping related tasks that you might need to focus on without creating a separate calendar for them.
2Do’s interface is completely customizable to display specific calendars in the order you want to see them in. You can view reminder items by calendar, tags, or location. If you specify a start date for an item in the future, it will not clutter up your current reminder list.

2Do plays nice with Apple’s new Reminders app. When you sync 2Do to iCloud, that data is automatically pushed to Reminders. Likewise, when you make a change in Reminders, that’s automatically pushed to iCloud so it’s updated when you sync 2Do. While it’s true that syncing is not automatic — at least not right now — it is quick and does not require WiFi (as other iOS reminder apps do).
Although folks with very basic reminder needs may find Apple’s Reminders app good enough to meet their needs, I think the power and flexibility of 2Do makes it worth the nominal purchase price. Its additional features and fields help keep me organized, whether I’m planning my next 1200-mile helicopter trip or just trying to remember what to pick up at the grocery store.
I love cool new apps — especially ones that keep me in touch with my friends and family members. 
Heck, as my husband drove off to work this morning, I could see his progress as he drove down the street! How cool is that?
Make use of the Temporary Share feature. This enables you to create an event with a definite end time. Anyone who accepts the invitation to share their location using this feature will automatically stop sharing at a predetermined time. This is a great way to connect with friends at a park or mall without having to worry about them seeing where you are once the event is over.
Disable Find My Friends when you don’t need it. On the device broadcasting your location (my iPhone, in my case), tap the Me button. Then set the option labeled “Hide from Followers” to ON. This removes your location from their devices. (I like to think of this as “stealth mode.”)
Open iTunes.
Click the Burn MP3 CD button in the lower right corner of the iTunes window.
If your playlist includes songs purchased at the iTunes music store, a dialog like the one shown here appears, telling you how many songs won’t be included on the CD. (You can click the disclosure triangle to see a list of the songs.) Click OK to continue.
If your playlist includes more songs than will fit on the CD, a dialog like the one shown here appears. Click MP3 CD.
You run out of CDs. Then click the cancel button in the status area.
Open iTunes.
In the top right corner of the screen that appears, you should see an Upgrade My Library box. (This box only appears if you have iTunes-purchased music that can be upgraded.) Click See Details.
A dialog like the one shown here appears. It asks if you want to enable iTunes Plus preferences so only the DRM-free versions of music appear (when available). Click iTunes Plus.
An Upgrade My Library screen appears. It lists the albums, songs, and videos that you have purchased for which DRM-free versions are available. Click the Buy button to upgrade all music and videos for the price shown onscreen.
Anther dialog tells you that the new songs will replace the old ones and gives you an opportunity to save the old ones to a folder on your desktop. Click Move to Desktop or Delete Files as desired.
The download begins. You can monitor its progress in the Downloads screen. iTunes displays the iTunes Plus window again so you can do some more shopping.

A few days later, another search brought up the cause for the problem. In iTunes, there’s a setting for each song or podcast episode labeled Skip when shuffling. (Select an item in iTunes, choose
