I can't seem to find an app for the iPhone that can do everything the Pixel 4 will do. That is, take a series of sixteen 15-second exposures and stack the stars and the foreground separately. But the Windows program Sequator can do that kind of stacking (with, of course, additional work) and I won't be limited to just 16 exposures. Plus, I only recently learned, the iPhone can take up to a 30-second exposure if you mount it on a tripod. Otherwise, it is limited to 2 seconds.

Oops. Corrections: It is fifteen 16-second exposures on the Pixel 4. And a hand-held iPhone can do 3-second exposures (by combining multiple shorter exposures). Some web sites claim longer hand-held exposure times but that's the longest I have been able to do.
