Three.do is a revolutionary reminders app that redefines how you remember small tasks. To add a reminder, tap three hints: the who, the what, and the when. This is faster than typing, faster than OK Google, is perfectly enough to remember the task in short term, and is something you’ll quickly learn to do instinctively.
I absolutely love this app. I use it every single day and I'm sad that I won't be able to use it when I upgrade it to a new phone. I wish it could be updated! Not sure what I am going to use to replace this simple yet very useful app.
