While the effect are nice, paying for an App that doesnt function properly is not worth any price. Im getting the same "blackscreen" issue as the other reviewer. I should have taken his warning and not purchased this App. The App freezes when trying to load a new picture an gives me a black screen. Ill reset my phone and it will work ONCE, then freezes again. To have to reset my phone each time I want to use the App isnt worth it even if they paid me to use the App. Save your money until this bug is fixed. Two thumbs down. :( Even though previous poster says App is fixed, it isnt. Wait for developers to fix it - Hopefully next update.
