App to automatically pick best photos

[AppleSmack]

My mum's iPad is full of photos, and we need to clear some away. For every shot, she's taken lots of photos, so I have choice, but I also have to pick through them by hand.

Which got me thinking... Is there an app (Windows or Mac or iOS) that will go through the photos, and select the best ones out of all the similar blurry, closed eyes, not smiling shots?

I know it's asking a lot of software, and it won't be perfect - I just need that first sift that'll cut the tedium of going through thousands of photos.

You can get through a lot quickly using Quicklook.
Just open a folder of pix. Select the first and hit the spacebar. The pic will come up.
Any you don't like, hit command backspace, and they'll be sent to trash.
A rate of 1 per second, or 3600 per hour is pretty easy to achieve.

Late reply, sorry...

Thanks for your suggestion, Partron22.

As a first pass, I used this app:
AVG Photo Cleaner and Manager
https://itunes.apple.com/gb/app/avg-photo-cleaner-and-manager/id926864471?mt=8
It analyzes the images, and groups similar shots together, with a suggestion of which is the best one. About 80-90% of the time, it picked the best shot: ones where the most people are looking at the camera, in focus. Spookily clever. One downside is the app is for the iPhone not iPad, therefore the low res thumbnails are even more pixellated when scaled to fill the screen.

Then as a second sift, I used Quicklook.
