The Android and iOS versions of Microsoft To-Do have been updated with faster sync capabilities and other new features.
Confusingly, the updates are otherwise a bit different on each platform.
On Android, Microsoft To-Do 1.39 makes it easier to move tasks between lists: Just swipe right on a to-do, tap the Move to button and choose a destination list. The To-do list in Microsoft To-Do has also been renamed to Tasks, which is already its name on other platforms. Finally, Microsoft also better voice-over support for completing tasks.
On iOS, Microsoft To-Do 1.38.85 also gains a new Undo feature so that you can go back in time if you inadvertently remove a to-do from the Important tasks list. Microsoft also fixed a bug that could cause the app to crash when you removed items from shared to-do lists.
As you may be aware, Microsoft has updated its To-Do app at a furious pace in 2018, in sharp contrast to the situation from a year prior. Just in recent weeks, it has seen Windows Ink support on Windows 10, tagging support, a dark theme, list sharing and steps, and much more.
