Apps have worse ability to track you than a browser, not better.

• no possibility of using third party cookies
• no possibility to fingerprint you using what modifications your extensions do to the DOM

The only extra information they get about you is a consistent but unique (as in not possible to correlate) identifier, meaning they know its the same device accessing the app that it was the other day as well. But they often know this from IP on the web anyway, and since it can’t be correlated, it doesn’t tell them much.

Devs would still (supposedly) be breaking the TOS, so they could get in legal trouble regardless.

Ooooh that’s gonna be super useful for pentesting.

Also, if the required APIs are available for USB host mode shenanigans, I’ve always wanted an app that can emulate a USB stick given an ISO. I’d start the app, select the ISO, and connect to a PC and boot from the ISO. The app could also keep the ISOs of specific operating systems up to date, and also allow me to add custom ISOs and even regular writable filesystem images.

Not to mention BadUSB scripts.

If an iPhone could do that, that would be AMAZING!

• Actual alternative browsers is the big one for me, I want real WebExtension-support
• Cloud gaming
• Programming language interpreters
• I have a friend that says they want porn apps, so for my friend, that
• Anything requiring NFC card emulation besides the few blessed use cases Apple graciously allow
• Proper photo backups (apps that aren’t Photos.app can’t automatically backup, you have to manually launch them)
• Emulators
• Open source software, because the vast majority of projects don’t have any actual income stream to pay for developer accounts
• Anything that Apple deems is already “OS functionality”, see the MDM app crackdown a while back
• etc.
