Not really. If you’re talking iOS Readdle Calendars 5 is so much better than the stock calendar for me, and there are so many better alternatives to Reminders - from supersets that use Apple’s Reminders plumbing (like Memento [review here]) to list apps that use Siri/Reminders to automatically import into themselves.
There are better mail apps, more full-featured notes apps (even though I use Notes too, for some things), much better podcast apps, better camera apps (though not available with a swipe from the lock screen), Kindle still has advantages in organization (and pricing), Apple Contacts is bare bones and barely updated in years, there are much better apps that utilize Health data, Google Maps generally is superior still after all these years, Weather is anemic compared to the competition, so is Calculator, etc etc.
On my phone I probably use Messages, Settings, Phone (but I also use Google Voice), Camera, Home, and occasionally Notes. That’s about it for stock apps.
