Ratings and Reviews
Ads hijack RAM, useless for professionals
I work in homes of clients doing construction and general contracting as well as on industrial job sites bidding big $$ jobs. I installed this calculator on my new iPad mini because I needed something on it to do little bids on this machine when I’m not using my iPad Air. Wow... it is garbage. Locks up after every keystroke because it’s trying to connect to its ad server, plays video ads constantly when connected to WiFi... I get thr need for a banner ad at the bottom that’s static (you did create the app for income, after all), but locking up because it’s priority is fetching ads before functionality of the app itself, where a dev thinks missing inputs from the client is acceptable while loading more ad banners instead of doing this function in the background... the dev obviously isn’t serious about the app and only cares about cranking in as much ad revenue as possible. If I was advertising online and saw my ad on your calculator I’d give my ad agency one chance to remove ads from crap programs like this or I’d fire them because the people who would be relevant customers would never use an app as broken as this, and I’d be wasting my PPI ad dollars on school children and people who didn’t have enough sense to check the App Store for any of the other 50 results for the search term “calculator” and download any other calculator app. At all.
These functionality limitations and ads in the app are compensated by the fact that it’s free. Please consider checking our portfolio for the applications with no ads that are available for download on different terms. Sorry for the inconvenience.
No Longer Usable
I have used this app for years, and it was one of the first apps I downloaded after getting my first iPad long ago (why Apple iPhones have a native built in Calculator App but the iPad does not makes no sense to me, and I Love all things Apple). The ads before were annoying but the app was still usable. However now there are full screen ads that you cannot immediately exit to use calculator, which is beyond infuriating. I understand when that happens if I choose to watch a video ad while playing a game app in exchange for an in game reward, but being forced to watch a full screen ad video which prevents me from doing some math on the calculator when I need a quick answer is so annoying I immediately looked for an option to upgrade to remove ads (which actually doesn't upgrade THIS app it downloads the paid version [different app, different app icon, same developer]), then I deleted this "free" version. Just do yourself a favor and buy the paid version (which I really like and I paid $0.99 for USD) and don't bother with this "free" version which is no longer useful when you need the calculator to work at that moment.
Thank you for your feedback. We are sorry for the inconvenience and possible confusion with the free/paid version icons. Glad the problem was solved eventually. If you'll have any questions in future - please let us know in the comments or drop us a mail at email@example.com
Have used for years, now uninstalling
Have loved this app, but now it has become so ad-packed, it isn’t usable. Ads now take up to 30 seconds to allow you to get an X to click them off, making using this program a long and tedious process. Am uninstalling after years of use, it is so unusable. Three quick calculations took over 5 minutes because of the ad interruptions. In response to the developer comment: saying you are releasing a knowingly buggy version with ads does not instill confidence that if I buy the paid version it will be better. I don’t mind buying apps. But I tend to base purchases on whether the developers have decent apps I can try for free during a trial period. The fact this app has gotten worse tells me the programming is not improving, and suggests money on the paid version would be wasted money.
In order to get rid of the ads you might consider downloading the full version of the app available in the store. Thank you.
