Become a more productive you, one card at a time.

It’s easy to procrastinate your to-do list without a clear first step. Tasks with large goals can feel impossible to finish.

Doo helps you procrastinate less. Your reminders become cards that are easy to start and easy to finish. The streamlined edit screen encourages you to create tasks that can fit on a digital index card. Each card shows up in a stack — instead of a list — so you can focus on one thing at a time.

Pick a few tasks each day and snooze the rest. Doo helps you create more consistent, sustainable habits. Reduce your anxiety and become a more productive you, one card at a time.

I bought this because of the snooze feature, and it’s not at all what I expected. “Customize your snooze duration”: Three predefined options is not customization. I want to setup my own times. It also doesn’t make sense that I can only snooze it for the set time. On Windows Phone calendar, the notification came on the screen, and I was given the option to snooze that reminder for one of several time options. Maybe I’m almost done with something and I just need five more minutes. Maybe I got caught up with something else and I need another hour. I also take issue with being required to enable notifications in order to start using the app. What if I just wanted to use this as a task organizer? Also, why do I need to enable my current location in order to set a location for a task? Why do you need to know where I am? Why do I need to give an address? Why can’t I just say “mom’s house”? I know where that is. Using the native date picker for setting a date isn’t great either, as it makes it complicated to set tasks for following years, later in the year, or if I need to visually see

Good design overall, though. I like the cards, and at least the snooze works. Without that snooze feature though, this just doesn’t do enough for me to differentiate it from any of the other task manager apps I’ve tried.

Best to do app for getting things done, could use one more feature


This is without a doubt the best gtd app for me, despite its lack of traditional to do list features like tags or contexts or project organization.

This app forces you to think about WHEN you will get something done, and presents you with one item to work through at a time. For whatever reason this motivates my lizard brain to actually do it, and put off less important work for later.

The only thing I don't like about it is the way it handles repeating location tasks. Why would I want to do something immediately at a certain place? It feels somewhat useless to me. I wish one could combine the where and when features of the app without relying on snoozing.

I also really wish there were a way to better organize your tasks: I like to think about the next actions I need to do for particular projects at once, and being able to group them by project, even if when only viewing them as a list, would make me feel more secure about my progress on projects. That's really the major problem with this app: it gets me to do things, which is the most important thing period, but it doesn't provide the security that I'm not missing something I need to do like more traditional to do list/gtd apps like Things or OmniFocus accomplishes.

Love this To-Do app!


Am very much enjoying this To-Do app! Love its simplicity. Graphics are very pleasing to the eye, in soothing colors. One thing I hope the developer will add is the ability to choose a custom sound for the audible notifications, as they default to Apple’s tri-tone sound (it would be nice to have a selection of different sounds to choose from, and I can’t find any way in the app or in my iPhone’s settings to change the alert sound) - After I submit this review, I will contact the developer to see if they can add this feature.

Update: Developer responded to my inquiry the same day I sent it, indicating that custom sounds are on his list for new features 😊
