Fuzel Awesome, a redesigned collage app of the original version which is now called Fuzel Legacy, is pretty awesome as its name suggests, especially when it’s FREE! Of course, there are in-apps purchases ($0.99 for 99 credits), but the free features the app provides are really sufficient to allow you to make creative collages.
I like its variety styles of frames and borders, many of which you can get from other apps but you have to pay for them. This app also allows you to customize the collage if you want to create something different from the existing templates, which are pretty eclectic already. And like other collage apps, you can adjust the thickness and roundness of the frame borders, add a frame color or pattern.
You want to write something and make it look cool? Sure! The app offers several label styles and fonts to suit your fancy. It also has stickers feature.
Have fun with Fuzel Awesome!
