Mono Day is a to-do app to make your daily life simple and satisfied.

What's the difference?

We miss, delay, forget things almost every day and it's okay. Instead of giving you red flags, this app automatically move around and rearrange the ones you might feel some pressure by.

You don't need to feel pressured to fill out every small detail to just list up your tasks. You can EASILY add more details whenever you want.

The habit of managing things is more important than ending the task itself.


- Focus on today's tasks
Each day, the app will automatically hide tasks that you don't need to worry about.

- Do it tomorrow
You can easily delay them by a single swipe.

- Manage all tasks in one view
You can view all tasks in a list, regardless of the date.

- Weekly and monthly overview
To give you a whole picture, weekly and monthly view will provide an overview of what you have done and what you have to do by each date.

- Memo on the date
Everyone knows that sometimes you need write a memo (not a to-do) to stick it on a date.

- Do it any time
Most of times, you don't know when it's gonna be done, but you just got to put it down somewhere. 'Any time' option automatically follows your today, without any other information.

- Repeat every week same weekdays
You know what? I need to take my dog for a walking every Monday and Thursday.

- Repeat every week any 1...7 days
And I need to clean toilet at least twice a week. How about you?

- Do it by date(s)
Well, this is what usually other to-do apps only have. But Mono Day can set many different dates for just one task. Who knows that you gonna attend only a few days for a week long conference.

- Search
Looking for something? Mono Day has a search feature.

- iCloud sync
Of course. Be more productive with Mono Day Mac app!

- Themes
We are all unique. Personalize the app with themes.

- Font size
My mom needs a bigger font size.

- Voice recognition
Just try it, iPhone is really good at understanding what you are saying. You don't need a keyboard to add a to-do.

- Fresh start
Forget the past, you can always delete whole data and start fresh.

- First weekday
Sunday? Monday?

- Highlight important task
Yup, the good old star mark is right there for you.

Mono Day is built by a one man team, and I love to bringing you frequent feature updates. I would love to hear about how to make your life even more productive. So please share your thoughts to playmatters.co@gmail.com.

Also looking for people who can help me on localize the language. Currently fully supported languages are English, Korean, and Japanese.

Lots of potential, but missing some things

This app is beautiful and has lots of potential, but some basic functionality is missing. Most importantly, I couldn’t find a way to delete (not complete) a task, either a single instance or a recurring event. I added a recurring task on the wrong weekday, and now all I can do is complete each one individually, which leaves a lasting record. Not sure if this is by design, but I’d much prefer to be able to delete mistakes like this. (Note that memos can easily be deleted by swiping left.)

I also wish I could mark a task as “in progress,” as a third state in addition to “not started” and “complete.”

Marking a task as complete is a little unintuitive. You have to swipe really far to the right to trigger the completion action. Also feels weird that you can’t complete a task by tapping the empty square to check it off, which would be the obviously first thing to try.

Not sure why none of my future scheduled tasks display in the “Upcoming” view...

Still, a lovely little app. Not sure it’s polished enough yet for the price, but looking forward to future updates!
