No search feature?

This has a lot of good information, but I’m on iPhone 11 and the search feature absolutely doesn’t work. I type something into the general search and nothing comes up/the screen doesn’t change, or I select the specific levels (beginner, intermediate, etc.) and it doesn’t let me type in the search bar at all. This really has potential to be a great resource but without being able to search, it’s not very helpful.

Agree with other small font size comments

Is there anyway to increase all font sizes across the board. After awhile of studying it becomes burdensome. Short time using and so far content is what I need (simple dictionary of grammar) but can’t continue using.

Too hard to read

This would be extremely useful if I could actually see the words but they are literally too small to read. I can only see about the top half of any of the letters in the example sentences. Please fix.
