I use the built-in Reminders app in iOS all the time, but unfortunately it doesn't like to save locations for later use. Reminder+ is an app that aims to remedy this problem by letting you save as many locations as you want, for as long as you want. Any place you frequent can be added to your list, and then later added to a reminder with a single tap.

The design of the app is quite beautiful, with an easy-to-use interface and neat features like delayed reminders. For example, you can have it remind you to email your boss about that TPS report a few minutes after you get to work, rather than immediately. That way you can at least enjoy some coffee for a few blissful moments before you're dragged back down to earth.

Reminder+ is only $2 on the App Store.
