Terrible app- do NOT buy. I lost so much data from this evening though it was set to automatically back up. Only some random bits did backup and apparently nothing can be done to retrieve it when I've contacted them about it

I like the simplicity of the app. I am able to write my thoughts and ideas down. It's cool that you can add a picture from your photos to your ideas. I like that it is simple so my focus can be more geared towards my thoughts. It also has a calendar approach and list view of the journal entries. The app is easy to use. It's a cool 😎 app if you don't need a bunch of bells and whistles. ;-) Thanks!

Clean simple app. Wish the save button weren't so small and difficult to reach at the top of the screen instead of somewhere near the bottom like the pencil button on the home page. It also doesn't automatically send you to the home page after saving, requiring you to manually go back.
