Evidently, it’s a toggle between % & $ for the discount. Downloaded it twice. Deleted the app out of concern Apple might have let a malicious app through. Developer has a bad track record of maintaining the app, evidenced by this possible lack of quality control. Would rate higher if QC was the only issue. ### 3/5 — UPDATE THE APP *2017-11-01, version 2.0* To the developers of this app, please update to the new compatibility for iOS 11. I can’t use it if it’s not updated. ### 3/5 — Needs update for new iOS *2017-10-16, version 2.0* Trying to open and get message that the developer needs to update the app to use on the new iOS. Please hurry! I use this app All The Time to calculate discounts and taxes! ### 2/5 — Issues *2017-07-27, version 2.0* I loved this app, but few months ago it started crashing when I go to type in numbers. The app needs a update big time. ### 4/5 — Crashing? *2017-04-23, version 2.0* I LOVE this app, it comes in handy, in fact my coworkers and I use it al the time at work, but lately it's been crashing a lot... Please fix the crashing issue, and please make it compatible with new iOS versions. Thanks! 😁 ### 1/5 — App doesn't work, free or pro! *2017-04-03, version 2.0* This app used to be great and very useful, I liked it so much that I bought the pro version. Now it just crashes all the time, so this purchase was a waste of money. This should be fixed!!!!!! ### 1/5 — Doesn't work right *2017-03-04, version 2.0* Used the free version for years and loved it. Stopped working right so upgraded to the pro version. Never worked right and now get a warning that it will slow down my phone because the app developer needs to upgrade the app. Made a purchase and am not getting anything out of it. Not worth it until major updates! ### 3/5 — Crashed *2017-02-19, version 2.0* Last time this app update was 5 years ago. What happen? I love and use this app a lot. It kept crashed on iPhone 7 Plus when I change prices. It kept crashed and I paid this pro version. Please fix the crash as I hope developer see this message and take care of issues please. ### 4/5 — Keeps crashing *2017-01-16, version 2.0* Good app it works great the one thing that bother me is that the app keeps crashing...please fix as soon as possible ### 1/5 — Just not working *2017-01-15, version 2.0* For years I used this app and loved it. However, after my latest update from Apple all I could see on opening the app was the suggestion that I purchase the pro version and whose message was blocking the actual functions of the app. I therefore bought the pro version thinking that would solve me problem. It went from bad to worse. Now when I try to open the app all I get is a large white square covering half of the interface and a message at the bottom saying - Please Consider Purchasing One Of These Great Apps. Frozen screen and no way of using the app - period. Not a king's ransom but a total waste of my money. ### 1/5 — Don't buy, no updates to app *2017-01-08, version 2.0* Don't purchase! I paid for the paid version but they are no longer updating this app. I'm having to remove it from my phone due to no new updates and it is slowing my phone done. Bummer because it was a great app. ### 1/5 — Consistently disappointments *2016-12-14, version 2.0* Every single time I plug in numbers, the app shuts down. Every. Single. Time. And this is the "pro" version. Save your money, horrible horrible horrible ### 1/5 — Boo 👎 *2016-11-25, version 2.0* Don't waste your money like I did!!! The free version was blocked by ads, this one is not worth $1.99!! Crashes and needs to be updated. ### 2/5 — Can't even use *2016-11-12, version 2.0* I bought this app because the free version was no longer usable because of the adds and now this one crashes when I try to use it. Fix the issue or I want a refund. This is ridiculous to pay 1.99 for an app that doesn't work. ### 1/5 — Always closes while using *2016-10-29, version 2.0* I was forced to buy this app because the free one quit working. So I pay then it constantly closes while I'm in the middle of using it. ### 1/5 — Shuts Down Immediately *2016-10-25, version 2.0* I bought the upgrade because the makers of this app made it so I could no longer use their free version. Now their "paid" version shuts down immediately as soon as I input the sales tax. Fix it or refund me what I paid to purchase it. ### 2/5 — Disappointed *2016-10-19, version 2.0* Just upgraded to the pro version-big mistake-its doesn't work-it keeps blanking out-again DISAPPOINTED. ## Most critical reviews (10 lowest-rated) ### 1/5 — Broken *2021-02-18, version 4.0* It was only a few months ago when I first got this app and it worked flawlessly. Today I needed to use for the second time and there are numbers missing from the keypad. Something changed and not for the good. Please fix. ### 1/5 — No way to contact the stupid developer *2018-01-03, version 2.0* No way to contact the developer of this app. Paid for pro version and the app doesn’t work because it needs to be updated. Developer seems lethargic n not interested anymore. Wake up!!! ### 1/5 — Not working anymore *2017-12-17, version 2.0* This app was working good when I got it, until I had so many updates on it now the app won’t work at all. The bad thing is a paid for this app, I guess that goes to show never pay for apps anymore. ### 1/5 — Doesn’t work with iOS11! Needs an update.. waiting *2017-11-29, version 2.0* App no longer works with iOS11.. I purchased this app and have relied on it for a long time. Now it’s no longer working because it requires an update.. how difficult could it be for the developer to update the app so that it will continue working?? Very disappointing! ### 1/5 — Useless *2017-11-15, version 2.0* I agree with the other review- you pay for a app, but this app doesn’t provide. Aggravating, useless and a rip-off. ### 1/5 — Will not work need update and i paid *2017-10-02, version 2.0* I paid for the pro version this app has not been updated for a while now and unable to open for a while now. Please update or refund those who have paid! ### 1/5 — Trial Crashes and Pro Crashes More *2017-09-13, version 2.0* The tax feature is great but the app is horrible. It constantly crashes all the time for quite some time now. Stick with the trial version because the pro is even worse - crash; crash; and crash. Guess I have to look for another better/working tax app. ### 1/5 — Not even worth the rating *2017-09-07, version 2.0* Purchased the pro app after the free one was not letting me use the app and now the purchased one exits out half through what I was doing so annoying ### 1/5 — App always crashes??? What did I pay for *2017-07-25, version 2.0* I paid for this app because it's a great tool, I can't even be on it more than a minute without it crashing!! ### 1/5 — Please Update !!! *2017-05-10, version 2.0* I used to use this app multiple times daily. But now it crashes almost every time I use it. ## Most praised reviews (10 highest-rated) ### 5/5 — Thank you *2018-03-03, version 3.0* Thank you for fixing this app. I have missed using it! ### 5/5 — Works ok by me *2017-09-02, version 2.0* Transferred this app over to my iPhone 6 and had the same problem a lot of others had. So I deleted it and redone loaded it and it now seems to work fine. Good job. ### 5/5 — Update please! *2017-07-16, version 2.0* I have used this app for several years and love the ease of use.
