Nope.

Do not install under any circumstances

For some unexplained reason this app locks the Privacy/Analysis file that is used to interrogate variable values used to calculate battery capacity. This happens even after the app is subsequently closed and the device restarted.
To solve the issue I deleted the app as soon as this issue was identified and strongly advise that you don’t install it until the developer explains why this happens.

Also, an incorrect variable is used so the battery capacity result is wrong.
