Other free calculator apps are extremely annoying bombarding you with ads. ### 4/5 — Needs split screen and app drawer *2020-07-23, version 1.3* Love this app but needs a better icon, and it should be compatible with app drawer/split screen so I can view it at the same time as Safari. Otherwise, great app. Very small (less than 10 megabytes), which a calculator app should be. Most calculator apps on the App Store are huge and bloated. ### 5/5 — perfect! *2020-01-26, version 1.3* This is just the basic calculator app that I have been looking for!! love that I can customize the color of the calculator 😍 many thanks for making it free of ads! ### 5/5 — Solid basic calculator. Thanks! *2018-08-27, version 1.2* It was really surprising how hard it was to find just a basic calculator without ads or trying to sell upgrades. ### 5/5 — Perfect for Basic Calculations *2018-02-01, version 1.2* This is just the calculator app I wanted for my iPad. It's free, has no distracting ads and has a clear, easy to use layout. It's also fun to choose from an almost infinite spectrum of colors using the slide bar. It's perfect for everday use like balancing the checkbook. Thanks for the nice app. It will get lots of use. ### 4/5 — ALMOST, what we need *2018-01-25, version 1.2* I realize that this developer made this app to be used just as a calculator without any sort of monetizing done to it but an update (if possible) would be greatly appreciated especially now that iOS 11 has the multitasking and slide over features! That would be really helpful if you could do it! Other than that, works like its supposed to, no BS ads, videos, monetizing or anything done! Thank you! ### 5/5 — Fudge fixed my biggest gripe with iPad. *2017-12-05, version 1.2* I'm not going to reiterate what everyone else said. Just thankful someone took the time to make a calc without ads. ### 5/5 — My God thank you! *2017-11-09, version 1.2* It is a pleasure to right this review! Ad free, really! Other apps were a nightmare, literally could not get through a simple couple of quick strokes without ads trying to force you into buying some crazy crap. Thank you thank you thank you! Just simply and refreshingly an app that works great! ### 5/5 — The calculator Apple should have included on iPad *2017-10-07, version 1.2* Not sure why Apple got rid of their calculator app (on my iPad upgrade to IOS 11) but this fine app is free with no annoying ads. Thank you to the thoughtful creators! ### 5/5 — Does exactly what I want it to! *2017-08-01, version 1.2* Thank you for making an App I can open and use for a quick calculation without wasting time on annoying ads. The calculator works great, and I'm so glad I found it after trying several other calculator apps that were very annoying. ## Frequently asked questions about Decimal Calculator ### Does Decimal Calculator have ads?
