I’m surprised I haven’t seen this before
This was on my mind because it seems to me that Space Empires could really use an app for book-keeping to avoid would avoid honest mistakes, such as accounting or remembering which ship counters have which technologies. (And cheating, of course).
Anyway, an app is by itself neither good or bad, but I can see it being a boon for some games (and a tedious draw for others). I’m old enough  that it’s not a draw, as I prefer to know the underlying systems of the game, but I do think that more apps that streamline said systems would be nice. I personally use the Mage Knight Dummy player app, as it saves me a few minutes of time each game. But I happen to like my games without technology, mostly. Still, I expect that there will be at least one brilliant game in the next few years that integrates board and app.
 Four and half decades today.
 And I do remember hearing about that Knizia Excalibur board game that had electronics integrated into the board, but I never recall seeing it. I wonder if it was actually published or just vaporware. This must have been a decade ago.
