yeah if you clicked the link it shows there is an iOS app.

343 has never been good at managing a Halo game. Not sure what OP is referring to specifically but 343 has made tons of awful decisions with the franchise. One thing that always bothered me with infinite is from what I remember the game has an enormous amount of tech debt because Microsoft loves to hire temporary contract workers so by the time a new contractor was hired and brought up to speed on the new engine they were developing/had developed, they barely had time to do much before having to be replaced with another contractor, which makes me feel awful for the poor developers hired on these temp contracts.
