It's all in the title. Do you ever feel overwhelmed by the sheer number of tasks on your to-do list? Adding all your tasks only to be faced with a seemingly endless list can make it hard to get anything done. That's why I created Underload, a to-do list app for iPhone, iPad, and Mac that only shows you one task at a time. You can add all your tasks, but you'll only see the next one you need to tackle. You get a clear, linear path forward, a singular focus. Best part is, it two-way syncs with Apple Reminders, so your tasks sync across all your devices and you can keep using Siri, HomePod, Shortcuts, and whatever other integrations you're used to to manage tasks.

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. ■ 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. ■ One field to fill in Tap +, type what needs doing, and add it. There is nothing else to fill in. ■ 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. ■ 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. ■ 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.
