Pics Smoother 4+

What this app is supposed to do is reduce the "noise" in a picture, or smooth the rough pixels and make the image look less jagged, which the app does accomplish. However, in order to do this, it makes the image blurry to smooth out the resolution. What you need is another app to sharpen the image, which should make it less blurry.
So don't give this app terrible reviews. It does what it's supposed to.

This developer has the capabilities to create a brand new type of camera app. The shutter button (volume button?) would trigger a sound that captures the attention of cats and dogs.
An instant AFTER grabbing the pet’s attention, the shutter snaps. The pet is therefore looking right into the camera when the portrait photo is taken.
The next sound the pet hears from iPhone camera would be different from the first, as pets get bored easily. Literally, the same sound twice no longer captures their interest.
A cutesy UI might appeal to general end users, but pro photographers need to take photos of pets too. Hence, RAW support and manual exposure and vignette and square aspect ratio are good ideas.
Please make this dream a reality.

It's not bad at all! But I wouldn't call the results eye popping. It works well for most photos. For some, however, it actually decreases the detail level and makes it look animated.
