Cảm âm sáo trúc is a free Android application developed by ZmikiSoft. It falls under the Lifestyle category and provides simple fingerings and beats for people who love playing the sáo trúc, a traditional Vietnamese bamboo flute.

The app is designed based on materials from the internet and forums on sáo trúc in Vietnam, which the author has carefully selected and edited. The simple fingerings and beats included in the app allow users to practice and play their favorite songs. Moreover, the app will continue to update with the latest fingerings and beats in the future. Users can also contribute fingerings and beats by sending them to the app's email, and the app will add the contributor's name to the app.

Another feature of the app is that it allows users to create their own fingerings by clicking the "+" button on the list screen. However, as the app's developer acknowledges, there may be some errors in the fingerings and beats provided, so the developer welcomes feedback to improve the app. Overall, Cảm âm sáo trúc is a great app for anyone who wants to learn or practice playing the sáo trúc.
