The only reason people still need office -- other than a niche of advanced Excel users -- is because no one, despite the last several decades, has managed to make a 100% compatible DOCX editor (not LibreOffice, not Apple Pages, not Google Docs). I'm guessing it's because there are aspects of it that MSFT keeps secret?
The only reason I still use Word is because I don't want to have to deal with random layout incompatibility issues when sharing docs with colleagues.
In general, I find Apple Pages much more pleasant to work with and by far my favorite word processor (and I have used them all extensively on Win/Mac/nix).
Microsoft was successfully sued by the EU for creating vendor lockin with their proprietary file formats. It is for this reason that the "X" formats (docx, pptx, etc.) are "open" and thoroughly "documented", e.g.:
https://learn.microsoft.com/en-us/openspecs/office_standards...
However, the formats are incredibly complicated, because they evolved from earlier formats that represented nearly the entire in-memory state of the editing software. To a first order of approximation, the .doc format _was_ Microsoft Word.

There are also (currently) no sleep metrics on app itself; you can only see them on the watch, which doesn't show much besides the sleep duration and an abstract representation showing where you might have woken up in the night.
