Updated 2018: 2Do has drastically changed its pricing. After raising the price to $14.99 in 2016, the developer has now made the app free, but with in-app purchases that unlock pro features such as sending to-dos to the app via email, syncing content with Dropbox and the iOS Reminders app, time- and location-based alerts, and more. The app also offers an Apple Watch app and an iPad app. Download 2Do Any.do (Free, with in-app purchases) is a widely used productivity tool that combines to-do list functionality with calendar and reminders features. The app follows you wherever you go, with versions that run on the iPhone, iPad, Mac, Apple Watch, and on the web. Use it to manage calendars and tasks, to assign tasks to family members, and sync with other services like Google Calendar and Outlook. Not Reviewed.    Download Any.do Update 2018: Awesome Note now offers an Apple Watch app, writing and journaling features, the ability to Touch ID-protect the app and folders within it, and more. It also packs in features for creating and managing notes (now with iCloud syncing), calendars, and reminders. Download Awesome Note 2 Update 2018: Clear has become more useful thanks to syncing with iPad and desktop versions, though the Apple Watch app was discontinued. It also supports Notification Center Widgets. In-app purchases unlock sound effects. The developer teased a major overhaul of the app in late 2017, but no new details have been revealed. Download Clear Update 2018: Ita now has an iPad version and syncs across devices via iCloud. It also supports printing. No Apple Watch app available here. The app hasn’t been updated since 2015. It still works, but it’s clearly not in active development any longer.  Download Ita Living up to its name, MinimaList (Free, with in-app purchases) is a stripped-down, black-and-white, text-heavy app designed to let you focus on your tasks and getting them done. It offers features including shared lists with other users, natural-language date input, a focus timer to help you track the time you spend on a task, support for Siri, Face ID and Touch ID for security, and much more. Not Reviewed.    Download MinimaList Update 2018: TeuxDeux still has an appealingly spare interface, but it hasn’t been updated with anything other than bug fixes since early 2017. The app is still backed by an in-app purchase-based subscription service, but the lack of substantial updates is a potential red flag. Download TeuxDeux Update 2018: Thinglist’s basic concept—creating lists around pre-defined categories—is still in place. The app hasn’t been updated since 2016, though, which means it’s not best for heavy users and probably not something that can be relied on in the long term. Download Thinglist Update 2018: Things has been updated with support for iOS 12, Siri Shortcuts, and many more features. With its frequent updates and support for the latest iOS features, it maintains its position at the head of the pack. Download Things Update 2018: Still my preferred to-do app. The user interface has been refined and the app’s smart enough to let you enter times like “next Tuesday” as dates and still get them right. A tag and category system helps keep tasks organized. Includes a helpful Apple Watch app. Download Todoist Update 2018: Like most apps on this list, ToodleDo includes an Apple Watch app. In addition, it offers an in-app purchase of sound effects, but its interface looks cluttered and overwhelming. Very few updates have been made to the app in recent years, including no updates in over a year as of this writing. It’s possible that ToodleDo is dying off. Download ToodleDo
