Been using this app for quite a while and now all of the sudden, every time I open this app, I get ads popping up. I go to restore purchases, and works, but when I close my app, ads start over again. This is a new behavior than before. I sent several emails to the dev and he/she has not responded. Good luck if you need support! Rating this as a 1 star app. ### 1/5 — Needs Serious Update *2023-10-27, version 3.1.8* This app is need of a serious update. It requires continuous “restore purchase” clicks because the ads keep popping up. The keyboard disappears regularly. I reached out to the developer with zero response. ### 1/5 — Ruined a perfectly good app *2023-10-15, version 3.1.8* Used to use it all the time and have deleted now. ### 5/5 — Simple and Easy *2023-01-13, version 3.1.8* Multiple and multiple uses!!! Love this ### 5/5 — Not pretty but it works *2022-05-19, version 3.1.8* I’ve used this app for percentage related calculations for many years. I use it frequently to determine principle amount given a known percentage and resulting percent; it’s flexible enough to ‘solve for x’ wherever the unknown variable may be. Also handy for compound interest, tax, percentage increase and more. As of 2022 the app is functional, however it hasn’t been updated in a long time. It was crashing for a short time in 2021, however it’s working as of May 2022. I wish it would be updated because it’s useful, but it may already be abandoned by its developers. Apple should include these types of functions in the calculator app imo because the quality of this type of app is lacking. ### 1/5 — Crash on Launch *2021-03-18, version 3.1.8* First let me say that I have greatly enjoyed using this app for quite some time. However after updating to iOS 14 the app is now cashing on launch for me. ### 1/5 — My favor app stopped working! *2021-03-17, version 3.1.8* I used this app for YEARS! And all the sudden it quits! ### 1/5 — It was my favorite but it stopped working!! *2021-03-11, version 3.1.8* The app was working perfectly until last year, and it is not opening anymore!! Maybe technical problem that it is taking to long not fixed!! ### 2/5 — Not working anymore *2021-03-08, version 3.1.8* Not working anymore ### 1/5 — Sparkles24 *2021-01-10, version 3.1.8* My app won’t open any more. Does anyone else have this problem? Loved it before this problem. Would give it 5 stars if I could still use it. ## Frequently asked questions about Percentage Calculator ### What can this percentage calculator app do?
