Hi folks. I've seen your picture. You're young. I'm 50. I'm a SaaS entrepreneur too (WeVu). Being 50 means presbyopia: declining near-field vision (reading glasses) that is highly light- and contrast-sensitive. Your parents all have this issue. Every single one of your users over 50 have some form of this. You will all be there.
I moved my personal to-dos from trello to Clickup. I love your product. But I couldn't figure out why I didn't like looking at it as much and it even scrambled my brain a little as I looked at it.. Clickup is 'prettier' from a design point of view. Eventually I figured it out. In the board view the task titles are just a teeny bit smaller and more condensed than in trello. The font weight in trello is very slightly higher.
It's a little better if I scale the browser view to 125 or 133%.
So: if you want people over 45 to not be put off by the large amount of 'stuff' on the screen and discombobulated by the text, which is REALLY important for immediate reactions during the adoption process, here's a simple fix: Allow 'bold' mode where all the task titles and status (column heading) are in bold. (You could also allow users to darken the background so the cards on the board view pop a little more.
Screenshot attached where I changed it to font-weight:500. Perfect.
An implication is that when you're doing user testing, you include over-45 or 'reading glasses' as a variable/segment.
