Large font is a basic accessibility requirement for people who struggle to read small text on mobile screens. Think seniors or people with glasses who may need some assistance.

1 out of 5 iPhone users have large font enabled. Android would have a similar metric. How do many of the finance apps fare in this regard?
This blog post is a review of some common investment/finance apps available in Australia.

Ratings explained
0 out of 5, no support for font increases at all, basically rendering the app unusable for anyone who needs larger font
1 out of 5 a major bug was found and the app was blocked/unusable
e.g. our bug with large text on the scheduled outage message would have been a candidate for this. The view wasn’t scrollable and the dismiss button was off the screen (I’ve fixed it last sprint) and the user wouldn’t be able to access the app.
2 out of 5 some elements were inaccessible or unreadable. Functionality of the app was reduced.
3 out of 5, everything is functional but some graphs/views looked odd
4 out of 5, app is functional and is almost perfect
5 out of 5 everything was perfect, no issues were observed
Even Google struggles
It’s ok if your app has some bugs around large font. Even google who is a champion of accessibility and inclusive design struggles to accomodate this feature. Google photos is mostly usable but when I tried to share an album with large font I just couldn’t access the link.
Do you have large font on your phone? What’s been your favourite app that supports this feature?
