Static BPM Analyzer

There are rare songs whose tempo changes on the way, but an app that can measure the tempo at 10-second intervals is now available so that you can measure the tempo even for such songs!
The tempo is automatically analyzed when you select a song in the music library, instead of the usual manual tap measurement type.
It may be a multiple or half of the actual tempo, but please note that it is limited by automatic measurement...
The tempo that can be measured is in the range of 60 to 200.
