From what I heard the European armies match Russias army in power overall - however I’m not sure if they could be as fast as Putin in getting this power coordinated to the Baltics (if there was a conflict, then it would take place there). So I think that should be the most important part to work on.
Furthermore I think that spending the money on more advanced equipment is better than a mandatory conscription, which would make the current shortage of highly skilled workers only worse (and there's also the question about how it would affect 18-year-olds personally).
Some banks like Sparda Bank, Sparkasse and VR in Germany have their own app at least on android as far as I know. And the EU forced Apple to open its ecosystem to other apps.
