I don't know if this fits any category on this site but I'm just curious as to this--> they say that the base iOS font is helvetica right? Well then what kind of helvetica bold is this?? I've never seen the letter 'a' with a curly spur like this. I like it though

I own the latest iPad mini and noticed it nearly everywhere. Do you think they just artificially bolded the Regular style which has a similar spur only thinner?
