I feel like my phone apps update constantly. In general, that’s a good thing, I assume. I figure they’re fixing bugs or whatever. However, I don’t run into issues very often, nowhere near the rate of updates, and nothing seems to change after the update.
Compare that to Steam games which update really infrequently and the changes are usually much more obvious.
With games, frequent and regular updates are mainly to keep people returning to the game and to fix bugs. Many apps already implement most of the features people need and dont really need new features for people to keep coming back, so the focus is moreso on maintaining compatibility and fixing bugs like crashes, as well as keeping up with OS updates (which tend not to affect games as severely, though can in some cases). Keep in mind theres a huge number of different phones which are on different OS versions with different system APIs, and msny devs dont test on a large number of devices. Desktop drivers and OSs tend to smooth over a lot of the hurdles there
