Those who work in a team can get everyone involved on Todoist, and then assign tasks to team members and get collaboration on projects. But it also stands out from others by allowing for sub-tasks, which are incredibly nice to have when a task has multiple steps involved. Todoist gives you what you'd expect from a task manager app: projects, lists, prioritized tasks, due dates, and more. Those who need a task manager with collaboration need to try Todoist, because it excels in that area. Todoist Screens (Image credit: Doist Inc.) But keep in mind that OmniFocus has been around for over 10 years, and is one of the gold standards when it comes to a powerful and flexible to-do and task manager apps on the iPhone that follow the GTD method. So while it's free to download and try, you will need to subscribe to continue using it after the trial period. Previously, OmniFocus was a premium paid app, however, it has recently switched over to the subscription-based model. There's also the unique Review perspective, which takes you through all of your tasks and helps you keep everything organized. Since OmniFocus is a compelling GTD app, you can also add notes and attachments to tasks if needed. Creating recurring tasks is easy in OmniFocus, and the Forecast view is excellent for seeing what your day or even week is going to look like.

It allows users to give certain tasks priority above others and focus on those first, and it now uses tags for better organization. OmniFocus lets users create projects and tasks for literally every aspect of their life. Plus, it is available on iPhone, iPad, and Mac, and the free cloud syncing service from OmniFocus keeps your data synchronized across your devices. However, if you need an incredibly feature-packed to-do app that follows David Allen's GTD methodology, then OmniFocus is the way to go. I was personally using OmniFocus for several years before I ultimately decided it was a little too much for me, and I was satisfied with the simplicity of Things.
