Description
Use your iPhone's high-frame-rate camera to measure the input-to-output latency of your text editor, device, game console, or television. Simply record a video containing the button press and the resulting effect on the screen. Is It Snappy? provides a frame-accurate scrubbing UI where the precise input and output times can be marked. The difference in milliseconds is displayed.
With Is It Snappy?, the responsiveness of a device, text editor, display, or video game can be objectively quantified.

Ratings and Reviews
Works perfectly
This app is very intuitive! It's easy to scroll through the frames and mark input, output frames. Having a list of results with custom names is very convenient as well.
Only possible improvement would be to somehow show sound level at each frame too so that it's easier to find the exact frame that a key/button bottomed out. Not a big deal though as I could tell visually by how my finger would bend at the bottom of a press.
Simple and genius
I love this! Was easily able to measure the input lag of my TV by having it mirror my laptop and switching from one browser tab to another.
The first time I ran it, it asked for photo access, which was weird. I allowed access to 0 “selected photos”, and it worked fine. (Actually it crashed the first time I clicked the camera icon, but after restarting it, it worked fine)
Awesome App, now you can measure snap
Does exactly what is says: let's you figure out if it's fast. Downloaded it and within a few minutes measured the latency on my Mac Book with iTerm! It also picked up the keyboard backlight.
The frame picking interface is almost perfect, but it should be slightly easier to go back a single frame. Not a big enough issue to dock a star though.
