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.

Nice app with some very useful tools, would be nicer with two additions, one would be like what rapidtables has on their web page that allows you to quickly calculate your rms by inputting the voltage and impedance of the speaker, it then tells you what your watts are. Second would be a FAQ about gains, not just setting them but also explaining gain overlap and why it's used, lots of confusion out there on that one.
