SimplyTodo

A to-do list should hold what you have to do, and nothing else. SimplyTodo is one list. Write a task down, check it off, and get back to your day. No projects, no tags, no due dates, no priorities, no reminders. โ Everything on one screen Every task you have to do is on the same list, newest first. There is no folder to open and no view to switch to. โ One field to fill in Tap +, type what needs doing, and add it. There is nothing else to fill in. โ Done today, gone tomorrow Check a task off and it moves down into Completed. Checked the wrong one? Uncheck it any time that day. The next day, finished tasks clear away on their own. Swipe a task to delete it. โ Themes System, Light and Dark are free. Five named themes recolor the whole list: Note, Terminal, Sepia, Slate and Blossom. Each is a one-time purchase, or buy All Themes for all five and any theme added later. Choose one and it is applied at once, so you see your own list in it before you pay. No subscription. โ No account There is nothing to sign up for. Your tasks are kept on this device. No ads and no analytics. SimplyTodo is in 26 languages and works with your device's text size and screen reader. A to-do list, and nothing else.

Verdict
hydo and SimplyTodo are too close to call on the numbers: across 6 compared parameters โ price, update cadence, ads and in-app purchases among them โ neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
