When I am working, I am never far from my laptop, why would I install productivity app on my smartphone in the first place? When I was part of an on call shedule, the only app I would accept would be the one pushing the notification like pagerduty. I also found out the hard way a decade ago that having access to productivity apps such as outlook usually meant to enroll your smartphone as a device managed by your IT and it was a big no to me.
