New app not compatible with old iPad

I tried to update my iPad to the latest version of the app. Since the first step to update an app is to delete the old one, I did. Then the PS app would not load on my gen one iPad Mini. Is there any way to go back and reload the old app?

Apple has stopped supporting the Gen 1 version of the iPads. Everything eventually becomes obsolete and is not supported anymore and it’s the Gen 1’s time. Unfortunately it’s not possible to load any versions of Practiscore on the Gen 1 tablets.
