Aimera

Aimera is a photo app to apply more than 100 filters to your pictures in real time. Just swipe from left to right to try out the different filters. Obviously you can also click on the filter button and pick one manually.

If you hold down the shutter button a menu will appear where you customize the button. You can choose from more than 50 different buttons, among them smiley faces, hearts, stars, different colors, and many others.

Other Aimera features let you take pictures with a timer (of between 3 and 15 seconds) and create simple collages. You can take several pictures with different filters to create a unique composition, and when you're done easily share the resulting image.

Aimera is an excellent photography app that stands out particularly because of the huge number of filters on offer. Its simple, elegant interface is also a big plus.
