I have an iPhone5s and I was wondering how to shoot 60fps videos since it can shoot at 120fps I want a reliable and a free solution please Thanks
It appears that the iOS app 60fps Camera will enable you to shoot 60fps on an iPhone 5s. I've not tried it, however reviews seem to be better than average and it cost US$2.99.
By the way, I googled iphone 5 app 60fps video and it was the 2nd link. You might find other options this way as well.
