Hi Grzegorz,
We discontinued the ScadaMobile app several years ago and it was removed from the app store about 6 months ago. Apple currently requires that all new submissions to the app store are 64bit apps, but the app was developed as a 32bit binary. Also, with the introduction of iOS9 Apple has broken some old apis that do not work correctly for the existing app. Unfortunately, it is no longer possible for us to upgrade the old app to the new apis. I am sorry that I can not give a better answer.
