Todoist

Avantages

Todoist is an excellent task management system that works well for both personal and business use. It offers the ability to easily organize projects and sub-projects as well as breaking tasks into smaller steps under one heading. It does take a traditional list format, as opposed to the visual card layout of Trello, but many people may find that they prefer this style.

The following features are ones that I have found to be extremely valuable in my roughly two years of using this software:
--Comments - the ability to make multiple comments on a task and even attach files has been great for both my personal and professional project management workflow.
--Assigning tasks - being able to assign tasks to specific team members is great for managing complex projects and tracking accountability.
--Integrations - integrations with popular services such as Outlook, Spark, Slack, Siri, Alexa, etc. make it easy and convenient to add tasks from anywhere. The ability to easily add an email is especially helpful.
--Labels - the ability to label tasks and projects and then filter based on those labels is extremely helpful.
--Natural language input - the ability to quickly and easily add a date, reminder, file in a project, or assign a person during the initial creation step makes it much easier to create detailed tasks.

Overall, I've found this software to be useful and would highly recommend both the free and premium versions.

Inconvénients

Sometimes, depending on the OS, the interface can be funky. For example, I find the interface for iOS/mobile to be slightly harder to use when it comes to easily rearranging projects/tasks or making comments quickly.

I'd also like to see better visual organization in the form of custom icons for tasks. Though the ability to change colors exists, this often isn't enough during complex use. It would also be highly useful to assign tasks to multiple people or groups, instead of one particular person.

Avantages

I've used several "To-Do" list apps in the past, but none of them have ever stuck, until ToDoist. What started as a way for me to keep track of work tasks quickly became my go-to app for keeping me honest with my never-ending list of to-dos both in business and personal life. The ability to create multiple to-do lists and share them with multiple (and unique) people sets us up for success and accountability. I also love being able to assign a task to somebody on the shared list and provide a due date for each individual task. I've also connected ToDoist to my Amazon Echo Dot, so I can ask support team to add items to my shopping list or tasks to my to-do list. When a task is completed and checked off by someone other than me, I love that I get a mobile push notification confirming that fact, in real time. Finally, having the app on my phone along with on my iMac makes for seamless use regardless of where I'm currently working. Overall, I've been very satisfied with ToDoist!

Inconvénients

There are some quirks to the program, but nothing that turns me off from using it. For example, each list is considered a "Project" and each project can have sub-categories. When adding a new task to a project, you are not given the option of a sub-category. Therefore, the task defaults to the bottom of the list. You then have to scroll to the bottom and drag/drop the task under the sub-category you want it to be in. I sometimes accidentally drop it in a fashion that it creates a sub-sub-category and then I have to manually change everything in that sub-category back over. I also have not found value to the Productivity Score I am given on a daily basis, along with a lifetime score. I appreciate the psychological benefit of game-ifying your to-do list, but it's just not something I find necessary.

Avantages

*Flexibility
You can use browser, android, ios, windows, mac device, apple watch, android wear or even use a gmail or outlook.
Todoist is right there for you.

*UI
It has the most welcoming UI of all todo managers. Of course, tastes are different. But I believe, no-one would disagree that Todoist is well made and developed with Love.

*Scalability and features

No being a full scale CRM does not stop Todoist from having everything you might want to have for your everyday simple lists, reminders and tasks. Todoist offers such features as a great approach to structure of tasks, flawless work on the prioritizing tasks and creating simple lists.

*Integrations and little things
Todoist offers a broad range of features out of the box, such as projects, links as tasks, scheduling and calendar integration.

You always forget to pick up or buy something. Or want to prepare for the day by creating a simple todo - this app is for YOU.

Inconvénients

1. More integrations needed. First of all calendars - at the moment the work there is mostly messy and is not optimized. It would be nice to have it in a compact and comfortable tab (calendar tab) and also add calendars on the go and display tasks or meeting in todoist. That would be a huge leap ahead.

2. Pricing of Todoist is not smart, to my humble opinion. First of all, they don't offer monthly payments, why not? Yes, I agree it's cheaper to pay for a year. But what if I am not sure. There are many todo apps and the pricing might be the only thing that would stop people from using todoist constantly, students for example. Would it not be nice to have more flexibility and options there.

Inconvénients

Not a straightforward way to sign up with an existing account on an Android app.
The trial requires a credit card info although it is easy to cancel.
An Android app does not move to the SD card.
Free version for Android lacks reminders/alerts.
It limits the list to 200 active projects and tasks per project in the premium version. It should be unlimited.
2048 characters per task name and 255 characters per project name It should be more than that.
The interface takes some time to master and lacks consistency.
The calendar feature is missing.
Personal and business lists are not plainly separated.

Avantages

I enjoy the incredible language recognition that makes it easy to capture tasks, set due dates, priorities, organize tasks by project, and apply custom labels to tasks. It's very simple and easy to use, which is uncommon among professional project management apps.
It is easy to break projects into sub-projects, and use sub-tasks to help break big tasks into manageable pieces. This makes it a perfect fit for small businesses or teams.
It also has great collaboration features, such as sharing tasks with others, assigning tasks and sub-tasks to individuals, and attaching files and comments to tasks or projects.
Todoist has an app for every operating system, including browsers, phones, desktops, the web, and even smart watches. I personally love the Chrome browser extension and Gmail integration.
I love the custom filters, they are incredibly powerful and allow you to build your own workflows. I use filters and labels to organize my tasks by location, by priority, by the amount of time each task will take, and by due date.
Todoist integrates with many other products such as Google Calendar, DropBox, Google Drive, Slack, Google Assistant, and dozens more. Todoist works hard to be everywhere and integrate with everything, making it a really powerful tool.

Inconvénients

Todoist only lets you view your tasks in list form. Most project planning tools give you a calendar view, a Kanban board view, or some other types of visualizations.
You also can't set due dates on projects themselves, and don't have a way to mark a project as completed. You can compensate for this by using sub-tasks instead, but it can get annoying at times.
The UI is very simple, and doesn't give you much control over themes. You can change the color of the title bar, but that's about it.
