Questions
Short answers, no runaround.
Short version: on an iPhone or iPad, Apple only lets a website send you notifications once that site is sitting on your Home Screen like a proper app. In a Safari tab it can't, no matter what any switch says. That's Apple's rule for every website, not something we chose or something we can work around — and honestly, it's a reasonable line for them to draw. It's just an annoying one to be on the wrong side of.
Here's the whole thing, and it takes about fifteen seconds:
That last step catches people out. If you'd already allowed notifications in Safari, the installed app doesn't inherit it — as far as your phone is concerned it's meeting Nudge for the first time, so it'll ask you again. Nothing has gone wrong. Say yes again and you're done.
Android and computers don't need any of this. Just turn push on in Settings and your browser will ask you there and then.
And if you'd rather not install anything: don't. Email reminders keep working exactly as they always have, and every other part of Nudge — your tasks, Break It Down, the Reset Room, all of it — is completely unaffected. You lose the buzz in your pocket, nothing else.
