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.

The only thing this APP can't and won't do? Make me a sandwich. Otherwise this is everything you could ever need for car audio! No more going to facebook to ask the EXPERTS. You are the expert now. Need to tune a box? Got it. Need to tune your amp? Got it Need to add a battery but unsure the size? Got it Wire in 62 new speakers? Got it! Need s new alternator? Shoot you can run more car audio now! Got it, because this app is designed to help you with every question you could have.

Big Fan, and long time loving user. I have used this app since before Covid-19, and have appreciated it's calculators, wire diagrams for reference and double checking myself, and for its Subwoofer Box calculator, which was ahead of the pack in terms of accuracy.
