PushMe is an incredibly easy and convenient way to remind yourself of upcoming events and tasks. Just write down the event or task, set the time you want to be notified, and you are done.

To make sure you don’t forget anything, you can set the message to be sent to you as a notification or text message.

Your reminders will be sent to you as a notification. If you don’t want to use a notification, you can simply set it to be sent as a text message instead.

If you don’t want to receive text messages, you can simply turn them off in the settings.
