Ratings and reviews

Great App! I use it all the time. Helpful when calculating simple things like ohm loads, built in frequency generator including sweeps, and wiring diagrams. Definitely worth the small price that is being asked. I highly recommend for anyone into audio. Once you see and start utilizing the features it will be your go to for alot of stuff.

When I was first learning this app had what I needed and provided it cleanly without over complicating it. I purchased it before it was free and before it went through this major visual overhaul which I couldn't be happier as it looks absolutely stunning.

Love this app. It is very useful in calculating enclosure volume and is pretty accurate too. Thank you !
