Gratus

If you feel that you need to express the fact that you’re grateful in a more meaningful manner, you might want to give Gratus a try. Or maybe you just want to remember a special moment in your life. No matter the reason, Gratus will be able to provide the right tools.
 
Users just have to write a simple text, take a picture, and post the content. That’s pretty much it. The application also comes with widget support so you can see that things you’re grateful for with a quick glance.
