Amazing app – Ramped Slow Mo Review

I have an iPhone 4s and envied everyone with an iPhone 5s or 6 because they could do ramp slowmos. But this app makes it to where I can. The only thing I would like to see updated would be a smoother way to choose the start and end points by dragging on the timeline. It only shows certain frames, I'd like to be able to slowly drag and pinpoint the location of it.
