Marmelo will browse through all your photo+video folders, so if you want to use a photo editing application to tidy up an image, feel free to do so and save the photo before importing it into Marmelo.
Marmelo works with square images so you have a basic cropping tool in the application. Once you've got your base image you can add sticker of cartoon images, messages, stars, and more. A number of sticker packs are included in the free download, and further packs are available to purchase in the app.
Once you have your photo all stickered up, you can share the image out to Facebook, Tumblr, and Foursquare, which is an interesting choice of networks to support.
Marmelo might not be for the purist, but I can see a lot of people enjoying a digital sticker app on their phone. You can download the app from the AAWP App Directory right now.
