Customer Reviews

Great idea, but a few nagging problems.

This is a great idea for an app, and it works fine; however, there are a few problems that should be addressed.
For example, the Compare Voltage function only allows whole numbers. Since a lot of audio work involves referencing +4dBu (~1.23 V), it seems obvious to include at least two decimal places.
Similarly, the Distance to Time function doesn't allow you to put any info about temperature or air pressure (remembering that our atmosphere is not an ideal gas).
With a few refinements, this would be a 5 star app.

Not working with iOS 9.0!!!

Love the app, but not working with iOS 9.0!

With iOS 9.1 installed, the app is running again like normal again! Amazing free application for audio engineers😊


Great set of tools and they all work flawlessly. Clean layout with many options for quick operation.
