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.

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.

Excellent To Do App

Picture Elegance

Honestly, this app and developer just gets things right. The app is gorgeous, user-friendly and functional for day-to-day use. More importantly, there are no subscription fees! I do not mind support developer; however, forcing someone to be locked into a subscription is just wrong - look at how well that has worked out for cable companies.

I have one simple request for the developers of this app. Please permit hyperlinks to redirect to Safari. It’s helpful when someone would like to add contact information or a website to visit as part of a project.


Much more helpful than I initially thought


Doo is a really helpful reminders app and has replaced my other reminder apps that always seemed either overly complicated and tedious to use, or were limited in some way.

The card interface really works with my brain too. It forces me to see everthing that I have to remember iin a a non-list format. I see lists everywhere in my life an it becomes easy to ignore them where I need to read each card quickyl in Doo.

The interface is easy to use and super fast to add reminders. It looks great and I is super helpful to have the MacOs version on my Mac too. It would be great if there were Siri integration someday and URL schemes to add reminders.

In addition, Doo has both nagging reminders and checklists which are indespensible to me. In the future, it would be great to be able to choose the length of time for the nagging reminders.

Hi 3point3! Thank you for the kind words :) URL Scheme support is now included! I'll also add your nagging reminder customization to the list of possible enhancements. You can find URL Scheme info at
