Have a look at 1thingapp.com. You can download it to your iPhone or there is a web app that works on all browsers. It's a handy little gratitude journal you can keep close by... and share with others if you wish. You can see what others around the world are grateful for... and you can reflect on what matters to you most as it keeps data on your gratefulness!
