This application is designed to:
1.- To calculate the ARL of a EWMA control chart given its parameters and makes a comparison versus the standard Shewhart (Xbar) control chart.
2.- To find the best parameters (optimization) to reach a given in-control ARL and to minimize the out-of-control ARL for a given shift.
3.- To plot an ARL chart, showing a comparison of performance versus the standard Xbar control chart.
In this application d = (m1 - m0) / sigma0.
And r = sigma1 / sigma0
The available languages are Spanish and English.
There is a twin application like this one working in Windows. The link to download it is:

This application is also available for iOS (Iphone, iPad)
and OS X (MAC). Just search in their stores.
Solved a bug computing the ARL of the equivalent Xbar chart when there is a shift in the variability.
