Real simple to-do list app for iPhone, Apple Watch
Why on earth would I make another to-do list app? Two reasons: At first I was looking for a simple app concept that would also make sense on the Apple Watch (before knowing about the official Apple tutorial app "Listing"). And it also was a nice exercise in design: Many of the to-do list apps out there have too many features and can easily seduce the user to micro-manage stuff instead of getting things done.
The simple but risky idea behind 3Lists is to create an artificial restriction for the user. There are only three lists to use (with unlimited items), no more. Items can be checked, moved and deleted, but that is it. Checked items are deleted after 24 hours. On the watch you can only check items but not create them. The UI is straight forward, with no gestures to learn. Customizable color themes allow for some nice personalization.
