Reminder has been updated with a pretty major improvement to the localization of the product. You can now get it with translations in most languages. Also, there are a number of bug fixes that will help with in-app purchases as well as a number of other places.
Reminder is integrated with the Unification app, so if you use that, you should get this so that you can have your reminders also show up in that notification app.
This is a solid app for setting reminders and keeping them all in one place with the ability to backup all your reminders to SkyDrive or restore your data from SkyDrive. Please check it out!
