The app name is "powerOne Scientific Calculator" by Infinity Softworks. This
company has actually been making this app for several years. I remember
purchasing it for my Palm Treo back in the day. Their web site is
http://www.infinitysw.com/ and they make versions for Palm (still!),
BlackBerry, Windows Mobile, and iPad/iPhone/iPod Touch. At least for the iPad
version, you can download several free equation templates from within the app.
