HarpNinja Diatonic Harmonica

★★★★★ Pure Awesomeness! I got this app to practice harp where it works great. Then I tried it with my bamboo flute(bansuri). It works great with flutes too!! Indian scale is harmonic and not equal temperament，for example indian G is ahead of western G by 1.96 cents. But that's not a problem for Harp Ninja. Great app. Thank very much.

★★★★★ I've taken a quick look, and the app seems great. I can't justify buying it until it allows for a manual or custom tuning option, or at very least a Power Draw tuning option. (It has Power Bender, which is awesome!) As soon as I hear it has Power Draw or custom, they can have my $25!

★★★★★ I recently just started to play the harmonica. I find this app very useful to see if I'm bending notes to the right note, also I found out online how to tune my harmonica by myself. I used this app to judge the notes position on the highlighted circle. My harmonica is now in perfect tune from using this app to go by! Thanks! Sincerely., Billy.

★★☆☆☆ Overpriced. There are free alternatives

★★☆☆☆ Doesn't seem to work as well on Android as it does on a friend's iPhone. Has a very hard time displaying any pitch let alone the correct pitch. Doesn't recognize chords either. Do not waste your money until these problems are addressed.

★★☆☆☆ I was recommended this app to develop my beginner /intermediate harmonica skills. I went to their website and saw a woderous demonstration of how this could be a great teaching tool with built-in songs and structured learning games. However, those features were for a different version unavailable for iPhone and Android phones. Only available on tablets and PC's. I contacted their support team and requested a refund, so I could in fact, purchase the more expensive version for my iPad. I did not receive a reply. Be wary, the diatonic Harp Ninja app is basically a glorified $19.99 guitar tuner. The $29.99 version, NOT AVAILABLE for iPhone or Android phones is the teaching tool app that is demonstrated on their website.
