This app generates a pure sine wave tone at the frequency it is set at. You can hook it up to your subwoofer, car audio or home system and test the bass frequency response of the system. It won't sound like much if you listen to it on your phone, so use a mini plug or bluetooth and connect to your sub woofer to feel the bass.
The app also includes some small samples of music designed to produce very low tones.
Feel the bass all the way down to 20 Hz and below, if your system can handle it.

Outstanding! Been using this for years to tune my subs in the car. Worked amazing for seeing what the Skullcandy Crusher Evo could do and Jesus Murphy it's like I shrank down my cars system. If only I could slide y'all some coin to remove that unintrusive ad I'd have done it looooong ago. I've never had a single problem from this app at all which is just wild to me. Devs seem to be slacking off around the world but not here.

Edit: You want to test your speaker bass, use this app, no ads, no cr.p. I came back after a few years and none of the other offers are as straight forward and simple as this. Does everything you'll expect it to do. You can test how well anything responds to low freq sounds aka bass

Needed something to test how bad I messed up my right ear bud. The good news is that this app did the trick! The bad news is that the bass response in my right ear bud is toast.
