This Android app has replaced Wunderlist for my quick, immediate reminders like buying milk or paying bills. ReNotify is a free app that allows you to create notes that lodge in the notification area until you address them, which makes it a lot more difficult to ignore your to-do list! You can create notifications that swipe away or make them stick so you have to click through to delete; either way the reminder is created and the app closes for you. How's that for time saving? There's a third option to keep it open if you need to create a list of items. This simple, effective app was created by secondary school student Liam Lang and there's a paid version should you feel like supporting young Irish app developers.
