I don't mind paying for apps I love. But five dollars or get a huge ad in your screen? I can't support that. ### 5/5 — Great Calculator! *2016-07-24, version 3.1.2* I sell parts and service for a truck dealership, I work in the field. What I use it mostly for is basic markup of products, so I use the markup/profit margin frequently. One huge timesaver is it keeps your calculations unless you clear a cell that way I can go back and adjust the other cells to fit the sale and not have to fill them in again. I tried several calculators and this is the best for me. The developer thanked me for the purchase and asked if there were any suggestions I would make. I asked that the titles be movable i.e. Move the most frequently used function to the top. They responded that they would put it on the list for consideration, just the fact that they responded was nice to see as it reflects how they would react to a problem. ### 5/5 — Best Tip Calculator *2016-07-16, version 3.1.2* Can lock the bill amount, enter a percentage, see the Tip. Then adjust the Tip amount to the dollar, and see the adjusted percentage with the total. Other Tip programs wouldn't do it. ### 5/5 — Exceptional Calculator *2016-06-13, version 3.1.2* Love this percentage calculator especially for business related needs. ### 5/5 — Exactly what I needed!!! *2016-06-11, version 3.1.2* Was looking for a calculator to do cost/tax/profit/total. Out of all of the free ones out there this one is IT! Once I found my exact calculator to use within the app it did exactly what I needed. Headache gone!!! ### 1/5 — Bummer *2016-05-19, version 3.1.2* Does not calculate profit margin. Mark up does not equal profit. ### 5/5 — Horny devil *2016-05-06, version 3.1.2* Omg Best app ever So straight forward and so much you can perform ## Most critical reviews (10 lowest-rated) ### 1/5 — Percentage Calculator *2023-11-10, version 3.1.8* No support, I paid to remove ads several years ago. 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. ### 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!! ### 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. ### 1/5 — Bunch of ads *2018-06-05, version 3.1.8* Whole bunch ads and if u wanna a ad free version then it’s $3. Not worth spending this much on this crap version. There r so many free apps available. It should have in-app purchase symbol on App Store. ### 1/5 — Avoid this company *2017-12-08, version 3.1.8* Had this app for years, then they put ads on, I paid to remove them - but they don’t go away. NOTHING you do will remove the ads. All 5 star reviews are comically fake. ### 1/5 — You must be kidding *2016-11-11, version 3.1.8* Dont waste your time, get another app. I used to use this app every single day. Just deleted and got something else. They sneakily added an invasive ad at the bottom after a recent update and did not mention in update text. They added a button to "stop ads" --but goes directly to buy without even disclosing the price (its a ridiculously high $5. Its an app calculator, guys...) I dont like feeling extorted or lied to. I would have just BOUGHT the app if it had been for sale, rather than this nonsense. Now I'll spend my money on some other app. ## Most praised reviews (10 highest-rated) ### 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. ### 5/5 — The Best Percentage Calculator *2020-03-25, version 3.1.8* I really like this app a ton. I use it regularly for finding out the local tax percentage on items I purchase online so that I can do my budget accurately. I'm able to just input my local tax percentage in the Sales Tax option, it's 6.5% where I live. And then I just input the amount of the items that I purchased online and that gives me the correct amount to deduct from my running budget. The Sales Tax function is really the only part of the app I use. But, I love that I have so many other options to use if I need them that this program offers. It looks to me like this app covers every type of percentage that you might need to calculate and then some. I also found it was worth it to show my support for this free app from the developer, by making the in-app purchase to remove advertisements. The Restore Purchases was a little slow at registering my previous purchase I made for that on my iPhone when I installed this app on my iPad. But it eventually kicked in and removed the advertisements for me, which is good. But I'm happy to make that purchase to show my gratitude for all of the hard work that was no doubt put into building this great app in my opinion. One feature request I'd like to make, though, is I wanted to ask the developer if he'd please make the app orientation on the iPad compatible for horizontal viewing as well please. Thanks if you'll consider that request. I use my iPad pretty much only in landscape view. So, I think it would be great if we had the option to view thus application in landscape as well. I'd say the only downside to the application is that it hasn't received an update in at least 3 years. Honestly, though, since it works fine for me and is still compatible with the current iOS build, at the time of my writing this review the the latest iOS build is - 13.3.1. So, I guess as long as this app continues to work properly I don't need any new updates. I would just ask the developer to please keep Percentage Calculator up to date and compatible with whatever future iOS updates come out please. Thanks for this wonderful and helpful application and God bless. ### 5/5 — Awesome app *2019-12-08, version 3.1.8* Great and functional ### 5/5 — Best percentage app *2018-11-19, version 3.1.8* I use this app frequently for my business to for discounts profits!! It has all you need to used for your personal finance. Also love the sleek look! ### 5/5 — Excellent App *2018-05-11, version 3.1.8* Fantastic app very useful and works perfect just paid for the Add removal as I really like this app it helps me find out my discounts now as I have a discount card as I work for the NHS so now I can figure out what I’m saving on a percentage % keep up the good work just needs an update for the iPhone X and it will be perfect so it can go full screen. ### 5/5 — Great, multi-featured app *2018-03-05, version 3.1.8* I love this app, it’s easy to use and has a wide range of calculations that are convenient. It has an elegant interface and is easy to read. I loved the app so much, in fact, that I paid to remove the ads. Well-worth the $2.99. ### 5/5 — Updated review *2017-08-23, version 3.1.8* I have to update my review. Just realized they have since lowered the price of the ad removal to $2.99 and I have concluded this is a decent price for an app that I use quite often (also got tired of hitting the ad by accident instead of hitting the keys). Hopefully the devs keep it up because this one is still the best around. I do have one request: shortcut keys to move up and down between rows (boxes). Maybe even a left and right to correct mistakes rather than tapping and dragging. Seems like it would make multiple calculations faster. Thanks! I went ahead and updated thinking, this is a decent app, I'll pay to have ads removed. Then upon launching the app I realized it was 5 bucks to remove them. 5 bucks!! You've got to be kidding me. Time to delete and find another....sorry but that is absurd imo. ### 5/5 — Very good *2017-06-30, version 3.1.8* Perfectly good app for working out margins and percentages very quickly ### 5/5 — Looks like the best *2016-12-02, version 3.1.8* After downloading as many percentage calculators as I could for review, this one came on Top. It's the best for my needs. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
