excuse me, but what kind of chicken-egg does he have??IF someone needs notification pushed to their phone, they can use his simple web/app. There is no chicken/egg here...
That's why I don't see the chicken-egg problem.
If I install any app, I do not expect to have to download dependencies to make it function fully. To that end, this solution is useless.
My outlook is simple: there are native implementations of push notifications on mobile devices. It may cost time and money to set them up, but please spend some time implementing them.
Maybe asking politely for clarification would be better than just denying whatever the parent said, but still...
To the guys who responded to this explaining the problem: Thank you!
