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.

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 😊

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.

Beautiful interface but...

The reason for 3 stars is because I truly wanted this app to work in terms of experience. And I paid $4.99. It has a beautiful UI which makes it pleasing and enjoyable to use. I’ve used other reminders on the market, but nothing balances craft and simplicity like Doo.

With that said, I find it very odd that by default it lands me to a blank view. It would be more intuitive if I could see the “All Reminders” view instead to give me context on what’s coming up and what I’ve missed in one place. And secondly, I can’t see the details or notes of an upcoming event unless I tap on edit. What the heck is that nonsense? Why can’t the card expand when I tap on it to reveal my notes? I’m comparing this to iOS’ default reminder app. Hate the interface but functions properly.

Please fix the experience. It’s almost there. ALMOST FOR GOODNESS SAKE! I’ve been searching and using a lot of reminder apps as I depend on them for my daily tasks. Doo is the closest to what I need.
