Smile Pet Clock

"This app seeks face of pet in your photo library, then build face only photo album.
This app also presents face only slideshow with clock.
Because this app consumes a lot of CPU power and memory during seeking faces in your photo library, the memory shortage might happen.
When memory shortage is detected, this app will terminate itself after saving information about faces detected in photo library.
If you meet such memory shortage with this app, please re-launch this app.
Please note you dont need to re-start your iOS device."
