Thank you! ## Most critical reviews (10 lowest-rated) ### 1/5 — Forced to review *2015-09-21, version 2.6* Loved this app. But as it now refuses to work without reviewing it I am! Very sad as I really liked and enjoyed it before. ### 3/5 — Ios9 not supported *2015-09-18, version 2.5.4* This was a very easy and competent app. No longer opens with iOS 9. Please fix ### 3/5 — No longer works iso9 *2015-09-18, version 2.5.4* I use this app every day but since ios9 update it no longer opens. ### 3/5 — Sweet *2012-04-02, version 2.5.1* Great app! Exactly what I was looking for ### 3/5 — Confusing *2012-01-15, version 2.5.1* I like the old version, but now as I am a beta tester I don't know if the version is different but it is quite confusing ### 4/5 — Almost perfect *2022-07-05, version 2.61* I haven’t found another app that comes close to the efficiency of this one. I love it. Just wish there was a slightly easier way to move between tabs but I’m nitpicking. ### 4/5 — Great app *2020-08-01, version 2.61* Well thought out app it does what I need done, so easy to use. ### 4/5 — Good program but requires rating *2018-08-14, version 2.61* Will lock if you do not rate it ### 4/5 — %diff *2018-04-24, version 2.61* Perfect So useful Colour change due ### 4/5 — Screen Colour *2017-12-06, version 2.61* Great App, just would be great if the orange keyboard could be a brighter colour.

Thanks ## Most praised reviews (10 highest-rated) ### 5/5 — Unbeatable percentage calculator *2025-09-20, version 2.61* Well aid out.Super easy to use and understand.Calculates percentages in all the ways you need it calculated.My only fear is that one day it is not compatible with a new version of iOS as no other percentages app fulfils the functions this does. ### 5/5 — Simple and Free *2025-01-12, version 2.61* This is by far a treasure if you are always calculating percentages. No ads, no cunning marketing tactics it is simple and free; deserves every bit of a 5 stars plus rating. ### 5/5 — great but *2024-10-05, version 2.61* I’ve been using this for a few years, I’m hopeless at maths, so it’s really useful when it comes to adjusting flour / water ratios when I bake. However a bug has crept in somehow, I think it occurred when I changed my ipad mini from gen 4 to gen 6, the symptoms are…. at the bottom of the screen the row of symbols 0 _ +/- Done are only half visible ( only the top third) and therefore difficult to select, it takes several jabs. ### 5/5 — Absolutely the BEST and most FUNCTIONAL app! *2024-01-27, version 2.61* If you work with numbers in any way shape or form, this app belongs in your phone. The developers have widely resisted the foolish idea to tack on unnecessary noise or annoying ads. I would happily pay for this app, and I hope it remains, and it’s current, pristine, amazingly functional form. To the developers, thank you! I hope you introduce away for us to optionally support you… Something similar to Wikipedia. ### 5/5 — Very useful *2023-08-21, version 2.61* Been using this app for years and always comes in handy! ### 5/5 — Great app *2023-05-24, version 2.61* I love this app….you can choose different percentage outcomes which I use all the time, because I don’t particularly need it to just work out a straight percentage of something. ### 5/5 — 6 out of 5 stars, a perfectly made app *2023-02-22, version 2.61* I use this daily to calculate the entry and exit point of my stock trades. Thank you for making such a clean, simple, well designed, functional, and easy to use product. Only small gripe, no sound or haptic feedback when you key in values. This is personal preference only. ### 5/5 — Pure and simple perfection *2023-01-13, version 2.61* I cannot say enough about this app! Unbelievably useful. Unbelievably simple. ### 5/5 — Love this app! *2022-12-09, version 2.61* Been using this app for several years without any flaws! It is great. I use it to help price my products, determine differences between numbers at work, grade tests for school. Highly recommended. Two thumbs up! ### 5/5 — Many uses *2022-11-19, version 2.61* This app is one of the best. Has been handy when dining out and shopping but is awesome when you need to buy something and want, say, a 15% overage. I’ve used this in construction projects, boating projects, and many others. Let’s add a little more functionality with maybe an area calculator including odd shapes and also volume including odd sizes. Maybe even a plain calculator or wait! How about adding fraction calculator?? Thanks for a great app! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
