One step using this app instead of four using a pocket calc. And it is visually pleasing. How do you send developers a buck or two for time and talent they graciously give away? ### 5/5 — Possibly could save my sons life *2014-02-03, version 2.1* I am terrible at calculating ratios, which has become clearly very important in my life since my son has just been diagnosed with type 1 diabetes....I was terrible at trying to figure out how much of a certain carb snack he could have in his allowance of them , and now it's a snap, and for the first time, I really feel 99% to 100% he is getting the right amount of insulin. This is amazing! Thank you for this app! Laurie ### 5/5 — Does EXACTLY what it says - love it ! *2013-04-26, version 2.1* This app is plain & simple and it works perfectly ! ### 5/5 — Amazing *2012-09-24, version 2.1* This app is perfect for what I need it for! I'm glad it is in the AppStore 😃 and I love that its free! ### 5/5 — Awesome *2012-08-06, version 2.1* Helps when doing ratios in math!!!!!!! Can't wait to use it more during the school year ### 5/5 — Excellent Application *2011-12-30, version 2.1* Quadratisch. Praktisch. Gut. :) This is one of the best simple and stylish app I've ever used. Really! I don't understand people who want something unreal from this app and rate it with one star. ### 5/5 — Great app! *2011-08-07, version 2.1* Gonna use it for those hard math problems once school starts! Best of all, it's free! ### 5/5 — What a great App!!! *2011-05-23, version 2.1* This does exactly what it say!!! It's great for helping me with homework and best of all it's free!!! I really don't get why it has bad reviews... ### 5/5 — Tool for Camera Assistants *2011-04-09, version 2.1* In filmmaking the assistant cameraman is often called upon to calculate a lens or distance to match a previous shot with a given lens and distance. As far as I can find there is no app designed for this task, but this little app does it perfectly if one just enters the first lens and distance in the top row and the known lens or distance for the second shot in the corresponding cell on the bottom row. ### 5/5 — Simple, handy, and beautiful. *2011-03-22, version 2.1* I'm a software designer, and I use this on a daily basis to resize elements. This app promises to do one thing, and it does it beautifully. I have no idea what the one-star reviews are about, or why someone would want "more features" in it. What, like I'm going to share solved proportions on Facebook? : ) ### 5/5 —  *2010-12-06, version 0*  ## Most critical reviews (10 lowest-rated) ### 1/5 — Potential to be Amazing *2018-02-25, version 3.1* If we could assume that some of the people wanting this app (like myself) were idiots and provide some basic info on using this it would be amazing. I know the tasks I could use this for but not the slightest idea how to achieve it using this app. The screenshot previews provide no help either. In fact they only further the confusion. For example. The x sign in the second screenshot top right field. How is that there? I assumed if I hit the +/- button I could get there but alas, no dice. Please help. I went to your website for help and then tried to find a contact form. I don't use Twitter or Google plus so that brings me back to here. ### 1/5 — Doesn't work *2015-10-21, version 2.1* I used this app before I updated to the new IOS, it used to work perfectly. Now with the new iOS, it doesn't work at all. ### 1/5 — Doesn't work with IOS 9 *2015-10-21, version 2.1* Was great prior to iOS 9, used it almost daily in creating and designing images for websites. But since iOS 9 it crashes, deleted and downloaded again, no luck. No response from support either. It's a shame, I'd actually pay for this app. ### 1/5 — Crashes with iOS 9.02 update *2015-10-08, version 2.1* The app now locks up or crashes on opening with the 9.02 update. ### 1/5 — Crashes *2015-10-07, version 2.1* Crashes ### 3/5 — App is pretty but.. *2012-04-27, version 2.1* App is decent looking but could function better than it does. Having to press the equal button is a hassle. Should be on the fly. ### 3/5 — Not that great *2011-12-07, version 2.1* I bought this app thinking it would help with more complex proportions like x/2x+5=2/3 or something like that. It is still a good app for finding simple proportions though. ### 4/5 — Please Offer Ad Free Version *2017-01-20, version 3.0* Pretty cool app ... except for the ads. I would happily give you 99 cents to remove the ads. **Developer response:** There are no ads in this app. ### 4/5 — okay,. *2009-08-20, version 0* this is nice and simple to use. update and add more things, then i'll give it 5 Stars. ### 5/5 — I use this app daily! Love the simplicity! *2021-02-28, version 3.1* I have not written an app review in a decade. But I wanted to give the developers a big thank you for such a clean simple and extremely useful everyday app. And thank you so much for updating this app to work with the latest iOS and iPhone 12 Pro. There was a period of time where it wasn’t compatible and thus wouldn’t even allow me to install it...I was super bummed because I literally use this app everyday. I looked for alternatives and quickly became annoyed that there really aren’t any. I absolutely love this app, thank you for continuing to support it!! ## Most praised reviews (9 highest-rated) ### 5/5 — The best Ratio Calculator *2017-11-25, version 3.1* I use this for resin ratios in my workshop, one of my most used apps. It would be wonderful if there was Apple Watch support so I could ask my watch to calculate ratios while using gloves and operating equipment. ### 5/5 — Absolutely Perfect *2017-09-13, version 3.0* If you regularly deal with proportional scaling of very large or very small things this is a perfect tool that eliminates cumulative errors that creep into complex scaling. No frills, no preconceived or assumed ways it will be used. Just a simple and effective solution to an annoying task. ### 5/5 — Love the color scheme! *2017-08-15, version 3.0* Reminds me of the original Apple watch bands ;) ### 5/5 — It's great! *2016-06-22, version 3.0* This made my life so much easier! ### 5/5 — Finally *2015-12-29, version 3.0* Thanks for fixing this app. I use it all the time. ### 5/5 — Coffee Brewing Ratio *2015-11-11, version 3.0* Use this app all the time when calculating how much coffee to water to use. So happy it works in iOS 9 now. ### 5/5 — Best coffee app *2015-11-03, version 3.0* Thanks for the update! ### 5/5 — Thank you for the update! *2015-10-28, version 3.0* I use this App everyday! ### 5/5 — Not working in ios9 *2015-09-19, version 2.1* I love this little app. Too bad after ios9 update it could not opened --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
