I don’t know it’s an interesting thought, one I’ve never given much thought too previously. I think it’s easy to say simplicity is key, but as for people just being able to ‘know timings off by heart’ is probably a little flawed, as surely a lot of people travel during peak times, such as mornings before 9am or between 3:30 and 6, when as pointed out times are generally different… routes take longer due to traffic in most areas and even then departures times differ to daytime, so in essence you’d have to check anyway.

I think perhaps there’s often this focus on daytime frequencies but where are these daytime travellers going? Retail and town centres aren’t exactly thriving, perhaps this where the whole things need flipping on its head - more evening services, peak time frequencies, services that are suiting leisure activities etc. Is a Sunday service justified anymore…

Back to the original point, I’m sure I’ve seen a service somewhere that has a bus every 45 minutes. And I can certainly see that being beneficial for services that maybe justify an uplift from 1ph but quite not 2ph. I think it’s worth remembering that not everyone is using an app, whilst many are, certainly pensioners are unlikely to be using an app, which is where there’s still a place for printed timetables.
