## Is It Snappy? Reviews in United States

### ***** "iOS 18 crash resolved, back to being a great tool"
A simple and amazing tool to learn about displays and software settings affecting latency.
-- TimeMonkey101, 2025-01-29

### ***** "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)
-- Mltsy, 2022-12-28

### ***** "Love this app"
It does one thing and it does it well
-- IrvingZisman, 2020-04-12

### ***** "Awesome app for pointing out controller lag"
This is awesome. Thanks!
-- CoryB10487, 2019-09-07

### ***** "Amazing"
Fantastic app.
 Wish there was an option to stop video from saving into photos and instead just stay in the snappy app
-- Debra Zeer, 2018-03-07

### ***** "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.
-- Game_Ender, 2017-10-17

### ***** "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.
-- VictorKilo, 2017-04-13

### ***** "Thank you!"
Just what I was looking for!
-- guru10, 2017-04-05

### ***** "We live in a flickery world"
Very neat way to measure and compare UI and other action-response latencies.
-- vdiv, 2017-04-04

### ***** "Nice work!"
Very helpful and well done. Thanks!
