待辦 To Do
Read full descriptionHide full description
A to-do list that is deliberately small. Open it, write the thing down, leave. Most to-do apps fail by having too much, not too little: before you can write down the thing you were trying to remember, you have to pick a list, a date and a priority. This app has none of those steps. • Write it down: tap +, type, press Return. Keep typing to add another — the keyboard never leaves. • Reorder: press and hold, then drag. Your order is never overruled by an automatic sort. • Steps: tap a thing to open it, and break a big one into small steps you tick off one by one. • Finish: tap the circle and it drops into a collapsed Done section. Tap it again to undo. • Progress: swipe a row in from the left and set how far along it is, in tens. • Delete: swipe left. = TIMELINE = This is the part other lists do not have. The timeline is not a calendar. It groups your unfinished items by when you wrote them down, and shows how long each one has been sitting. Anything older than a week is marked. Dragging a row never changes how old it is, so the timeline always tells you the truth — you cannot tidy it up by rearranging. One tap flips it around to show what you have actually cleared. = URGENT OR IMPORTANT = Urgent and important are two different questions. Most of what feels pressing only answers one of them. A small 2 × 2 in the corner of the list counts what is still open in each group. Tap a box and the list shows only that group; tap it again for everything. Two optional toggles sort a thing while you are still typing it, and you can change them later by opening it. Ignore them and it stays unsorted, and writing it down is exactly as fast as it was. There are no due dates, no reminders and no notifications here. Urgent is a judgement you make, not something the app works out from a date. = YOUR DATA = • Everything is stored on your device. No account, no cloud, no sync. • The text of your items never leaves your phone. • Anonymous usage data is collected — which screens were opened, counts, ages — to see which parts are worth keeping. • No ads, and your data is never sold. = ALSO = • Traditional Chinese (Cantonese) and English, switchable inside the app with no relaunch. • A quiet light design on warm off-white, and it respects larger text sizes. • Free. There is a tip jar in Settings if you want to support it, and skipping it is completely fine.
