There is nothing like keeping a good old “to do” list when it comes to ensuring that you don’t forget important tasks. It can also help you prioritize a laundry list of things to do accordingly. If this is your cup of tea, Todoist is the souped-up digital version that works on all your devices, including Android, iOS, Windows, OS X and even as a browser plug-in for Chrome and Firefox.
The basic free tier gives you an opportunity to test out the service, while ToDoist Premium costs $29/year and adds a long list of features including attachments, location alerts, reminders and automatic backups, among others. And existing Todoist users get three months free for buying someone a ToDoist Premium subscription as a gift.
