Remind Me Later can be a useful feature of iOS, except that it’s limited to reminding you about phone calls only. Fans of the feature will be happy to know that the jailbreak tweak AnyReminder makes it possible to add these reminders to other iOS apps, such as Messages and Mail.
For example, say a text message arrives and you device is locked. With AnyReminder installed, tapping the camera grabber displays options to Dismiss, Launch or Remind Me Later for this particular alert. This menu can be enabled to work with Notifications, Safari, Mail and Messages in addition to the Phone app.
This means notifications from any app can be configured to display the Remind Me Later option. Once installed, AnyReminder Settings will enable or disable Remind Me Later for individual apps, and you can set timelines for reminders. The Share button in iOS stock apps offers AnyReminder access as well. There are also options for dismissing reminders and setting location-based reminders.
AnyReminder is available on Cydia from the BigBoss repo for $1.99. Check here for instructions on how to jailbreak iOS 6.x with evasi0n. You can also find out how to purchase and install Cydia tweaks with this guide.
