HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (22 new ratings a month on average since launch): revenue grows with new ratings, more slowly for apps that collect ratings fast. Tested on 418 apps with verified revenue: typically off by about 2 times, and big earners tend to come out low. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

WHAT THEY ASK FOR
  • It would be nice to put some Cent reading +- instead of just +50 Or -50 in the far left and in the far right.For a more precise tuning it would be nice to read cent by cent. 4★, Mar 4, 2018

ピタゴラス音程ずれる

音律ピタゴラスA=430設定です音程が結構ずれていて雅楽の調律に使えない　修正してください　iOSは26です

★★★★★May 24, 2026
古典音律を設定した時、とても不正確で使えない。

2023年9月にレビューした問題点が、2026年5月現在、解消されていません。 古典音律で使用した際、とても不正確です。 平均律のみで使用する場合は良いですが、 例えば、中全音律の場合は、2ヘルツから3ベルツの誤差が生じています。 これは、使用に耐えられない誤差です。

★★★★★May 20, 2026
É muito bom e fácil de usar

Interface muito amigável, bonito de visualizar. Comparando com afinador de headstock, muito bom. Boa precisão. O fato de indicar o Hz da nota captada também é bem didático e ajuda ainda mais na acuracidade da afinação. Aprovado e super recomendado!

★★★★★Apr 12, 2026
