Set up your iPad with a keyboard and this can’t be used. No, you can’t rotate the iPad to portrait orientation when it’s arranged with a keyboard. It appears to be the world’s most difficult task to include a landscape mode if you develop a calculator application. This is not the only calculator without a landscape mode. ### 5/5 — Great App! *2020-05-30* Every time I downloaded another calculator app I was hammered with adds and requests for upgrade fees with noise and load music. I really like this one. Quiet, basic, with choices of key boards. It also runs on my old iPad2 which can't be upgraded anymore. ### 5/5 — Excellent calculator *2018-11-29* Clean and polished. I like that you have the square root button in default portrait mode which is very important for my work. Thank you! ## Frequently asked questions about EDS ### What types of calculations can EDS-5 Multifunction Calculator perform?
