Ratings and Reviews
Now iOS 11 Compatible.
An incredibly useful resource. All of Abramowitz & Stegun, nicely indexed, at your fingertips. And now iOS 11-compatible. Best $5 I have spent on the App Store.
This app has a huge amount of information in it, without any fluff. It has multilevel menus which makes it easy to navigate and find things quickly, such as formulas, graphs, and calculators... it's all here and very convienient. No buying (or renting) bits and pieces with in-app purchases, either. All in all, it is a really great and useful app!
HMF needs some UI work
Despite this app being a great resource of information, it lacks a good UI. The biggest problem is that the table of contents cannot be hidden or slid over to prevent it from blocking the page content which forces the user to slide the page back and forth to read. In the landscape mode, the ToC bar seems to be OK; but should still be hidden.
Information is dense so, I cannot imagine trying to use the app on an iPhone without going bonkers trying to read it. The ToC issue would be exceedingly annoying.
Good info despite the execution of the app design.
With Family Sharing set up, up to six family members can use this app.
