Apple recently introduced Reminders app in iOS, a very useful software to create reminders that can also be based on the geographic location of the iPhone (for example, iOS will remind us to fill up gas in the car as soon as we move away from home).
LockMemos is a new Cydia tweak available on Cydia Store. Whenever this tweak is active, your iDevice will display an alert in iOS format to remind you about a specific task and that alert will be glued to your screen.
With LockMemos you can enter and leave handy reminders that are always be visible on your iOS device lock screen. Tweak supports inserting multiple reminders (up to 4 in the same lock screen) and can be very convenient and useful for those who do not want to create a reminder time or use the GPS location, but a reminder that is always visible when needed.
