Deer is a note/to-do application that structured fragmented information. Convert whimsical ideas, class notes, and to-do items into mind maps and checklists.

"Big things turn small, small things tick off"
First set a big goal, then break it into several small goals, and complete them one by one. 'Dear' supports splitting 1000 levels of subtasks. You can easily split the task and focus on completing the split subtasks.

"A list, but not simple"
Don't look at the list with only one column, click on each item and you will find that your thoughts will become very clear. Because the details page shows all the sub-tasks you split before, including all the parent tasks. You can modify their content and structure at will, as long as they can fit your mind.

"Simple and complex coexist"
You can completely treat a list as a list, record the information and view the information according to your habits; you can also use it as your information collector, split and summarize the information, sort it out and store it in it clearly, when you want If you want to focus only on the details, you can use the powerful filtering and sorting functions of "Task Flow" to put it at the top of the list (it will also appear at the top of the widget).

beau c. ,

awesome. really.

not huge on reviews, but this warrants an exception.

Alien Ware ,


For me this is a program which is a true extension of the thought process. It becomes intuitive like breathing and combines cognitive, spatial, visual, auditory, kinesthetic, tactile and pre-cognitive processes of the mind. That being said, this is great for people on the spectrum whose minds move faster than computing algorithms.
Thank you

Has potential, please keep it simple

This app has a lot of potential, please do not drown it with additional features the mind mapping / task features are what many of us want to work with . Some formating for the the text cells would be nice ie. lists and other standard features. Along with the ability to set character length on the nodes. It needs a few inteface tweaks in terms of deleting nodes with a swipe left at the root node would be nice but all in all it has a lot of potential. This is the first review I have ever submitted on an app so again please dont ruin your fan base with to many bells and whistles the do one thing and do it well is the best advice this Sr. Business Analyst can offer.

Developer Response ,

Thank you for your use and your valuable suggestions. We are now trying to add some text editing functions, and encountered difficulties, it may take a month to update, but please rest assured that we will continue to optimize it. After all the main functions are completed, we will add some personalized functions to meet different needs. It is really inconvenient to not be able to delete nodes in the list. We consider adding the function of sliding to delete from the right edge of the screen. We will work hard to develop more useful features to improve user efficiency.
