Stupendous!

Due simplifies reminders to get important stuff done on time.

I dont spend my time tinkering with a GTD system for every little reminder, at the expense of actually getting things done.

Due lets you nail down a future task or event at a specific time with ease, and move on knowing you will be reminded.

Due also lets you quickly set dozens of reusable reminders for rubbish day and birthdays. Crazy irregular timing is easy.
Also Due provides a raft of new and reusable timers for fussy coffee brewing and other timed tasks.

Due has been around (and on my home screen) since my first iPhone in 2008. Use it/Love it many times a day.

Watch the launch video. I learned new tricks after all these years.
