If you often fall behind on finishing tasks you set out a few hours ago, you must consider using a to-do list or reminder app to ensure you never miss out on a task again.

A to-do list or reminder app, in simple words, is a task management program. It lets you create lists for tasks you want to perform and set notifications for those tasks, so you’re alerted when they are due and don’t forget them.

Google, the search-engine giant, offers a variety of apps to cater to the varied needs of a large number of users. Tasks happens to be one such app for setting reminders and creating to-do lists.

As its name suggests, Google Tasks allows you to create, manage, and edit your tasks from anywhere, anytime, so you’re always on top of what you need to do. Plus, you can add details for tasks and even break down your tasks into subtasks to narrow down your focus.

Other task organization options include the ability to organize tasks by date or priority, cross-platform sync capabilities, and integration with Gmail and Google Calendar to streamline task and reminder creation. Having integration support also means you can trace a task to its source email to find out more details about it.

Choosing the Right To-Do or Reminder App to Keep on Top of Your Tasks

Listed above are some of the best to-do and reminder apps you can use on your Android or iOS smartphone. While all of these apps can help you create task lists, set reminders, and do a bunch of other things, we recommend you try out these apps yourself to find the best reminder app (or to-do app) out of this list that suits your requirements so you can stay on top of your tasks, and ultimately, be more productive.

FAQs About To-Do and Reminder Apps

Things 3 gets the crown for the best to-do app for iPhone due to its extensive feature set and integration support for a wide range of apps and services. However, all of those features come at a premium. Alternatively, if you wish to not spend on a task management app, you can try out Google Tasks (for a simplistic to-do app) or TickTick (for more advanced to-do and reminder operations). Both of which are available for free on the AppStore for iOS and iPadOS.

Google Tasks is the simplest to-do and reminder app for Android devices, thanks to its clean and user-friendly interface and integration with Google Calendar and Gmail. However, since it can be limiting for some users, an alternative we would recommend to most people is TickTick, which gets you a lot of advanced features without any extra cost.
