To-do apps are one of the best ways to keep organised, easily cataloguing information that you would otherwise forget on a later date and offering timely reminders.
It's often the smallest things that you'll forget, like toothpaste or paracetamol when shopping. Keeping these things in check makes the world run a little smoother.
There are a lot of to-do apps on the market from a lot of different developers. Google makes one, Microsoft makes one, Apple makes one, and a host of independent developers make them.
We tried out five to decide which is best.
Who makes it? Google.
Strengths: The interface is nicely designed with big "cards" for each task (or note) which can be tweaked to make them stand out. Notes can be rearranged by importance and the search feature is comprehensive.
Weaknesses: The app is tied to your Google account which means if you use another service, such as Outlook, it won't be for you.
Strengths: The app is simple, clean, and works offline. Apple updated Notes on Mac earlier this year, introducing a syncing feature that keeps everything together. There is also support for Notes from multiple accounts, including Yahoo, Google, and iCloud.
Weaknesses: The app is iPhone-only and doesn't offer reminders (although Apple's Reminders app does).
Price: Preinstalled on iPhones.
Who makes it? Any.do.
Strengths: The app is nicely designed, with a clear interface that resembles a lot of Google's design thinking. Panels fade in and out with a sliding animation, for example. Syncing is available across devices.
Weaknesses: Not all of the app's features are available for free and the app offered an annoying "What are you up to today?" notification every morning.
