Why you need it?
For moments when every frame matters.
For situations when even blinking seems unreasonable.
Touch the screen once and it's on. Instantly.
Don't waste a second. Don't miss a thing.
It's plain simple and simplicity is exactly what you want when you witness your baby's first steps, your friend finally nailing the trick he's been working on for days,
or just your cat looking absolutely cute.
Something will happen.
