Keep App - Fastastic Free App for Android Users (Keeps You Organized)

I used to write everything down.  Monday to Sunday, a list of things I had to do whether it's drawing, design, freelance, personal project and the list goes on.  I killed a lot of trees.  Fear not android users, for people like me I have come up with a solution.  I'm going to tell you to use the pre-installed app that comes with a lot of android phones that other people have designed and developed...

it's useful and looks might pretty & intuitive

You can make notes for each day of the week and make a list of it.  You can check them off, and even set a reminder for it.  I looked for 20 seconds to find an image online.  As you see above, you can change the color of the background to diversify the content.  I have 7 green blocks created for the 7 days of the week.  The other blocks have different colors to separate the content.  You can even take images and add them there to make a note of it.

By no means is the app perfect, but it's still fantastic and free.  The reminder for example is incredibly basic and you can't add your own sound effect for it to make it more prominent.  It would be nice if there were different sections or folders.  That way, you have one section where you have weekly list, another section for work list, and another section for other.  Arranging blocks could use a bit more fine tuning, though it's still pretty good.  Add subsections to lists would be nice.  So Project 1, has 2 mini lines with work #1 and work #2 for example.  Enough of these ramblings however.  You need to have some type of list app/routine to stay on top of things, and this app does it for free.

iOS users, the app doesn't exist for you all.  I'm certain there's similar apps for iPhones, but I can only help android users in this case.
