Wouldn’t it be amazing to have a ruler in your pocket all the time? Well now you can! With the Acoustic Ruler Pro [0.99] from Florian Student you can measure anything, anywhere! To measure with this app you need an iOS device with a built in mic. Then you need headphones with a mic or without a mic (it doesn’t really matter there). This app is sort of hard to explain in writing. The best way to understand how this app works is to watch the 2 videos that the developer made about the 2 measuring modes. Below are the 2 videos and a quote from the App Store on how the application works.
How it works:
“The app works by clocking the time delay of the emitted sound waves. There are two different operation modes: a single device operation (with headphones) and a dual device mode for measuring the distance *between* two devices. Read below to find out which modes work on your iOS device.”
Single Mode
Dual Mode
As you can see that’s pretty amazing! I feel that the videos were the best way to explain how the application works. This is definitely a must buy! My final rating is 4 out of 5 stars. Most of the time the measurements have seem to be very accurate. You can go download Acoustic Ruler Pro for just $0.99 from Florian Student here.
