Seems to work on the devices I have used it with. Your device definitely plays a big part, as the app is only as good as your microphone and the onboard processing. Still works well on burner droids from Wal-Mart and the like. If you're in a bind and need a quick tune, try it out!
Not the best but certainly not the worst. I wouldn't try tuning in standard Open Keys as this App will just fluctuate all over the place. Harmonic tuning is slightly better but only just. Best Tuning App out of the 7 I've tried so far & had to uninstall. I guess the motto of story here is I better dig out my own Bass Guitar Tuner & replace the battery as all the producers of these Bass Guitar Tuning Apps just ain't cutting it. If you really stuck for a Bass Tuner give it a try but to be honest I wouldn't endorse this. I so want to give a Bass Guitar Tuning App a great review on here but there's none on Playstore that I can I say is up to par.
It's absolute garbage. It will jump over so many notes and you can barely find out what note you're at. After five minutes you'll be tuning by ear. Waste of space on the phone
Poor Implementation App listens to entire audible spectrum, and doesn't filter at all. Thus if there is any static or background noise, or even mic feedback, tuning is TOO delicate. To improve they need to smooth/filter frequencies outside a reasonable bass tuning range. As it is, I can't even begin to tune a Low B with this pile of wasted code. Try elsewhere.
Tuned my bass to this and tried playing along with a song I knew and found I was not in tune. Went and tuned with TU3 and then immediately with Fine Bass Tuner. Fine Bass Tuner said I was significantly flat. But when I played along with the song, I was perfectly in tune. Total crap, don't bother with it.
