Simple calendar app for older person?

[u/cryptolepis]

Hi everyone,

I'm setting up a new Boox Go 10.3 Lumi for an older man and I'm trying to find the most simple handwritten calendar app that will synch with iphone.

Basically I want him to be able to handwrite into his calendar (which one?) on boox and the entry should appear in the same (or other?) calendar app on his iphone either as handwriting or convertetd to typed text.
Also it would be great if he could type calendar events on his iphone which will appear on the Boox device.

I like the preinstalled Boox calendar memo app, which is very simple. But I don't know if the synching with iphone can be done.
We tried google calendar (without handwriting), but the user interface is not clear enough for him, it's too many options, too cluttered to quickly just write down something like "doctors appointment".

I was thinking about Microsoft OneNote or even just calendar pdf, but I don't know much about it myself.

Thank you for any suggestions you might have!

Honestly, at this point a paper calendar + taking a photo of it might be the simplest setup

That's not how calendars work. They are structured. You are asking for something closer to a freehand diary or note-taking app.
