Plus you can personalize the colors. A simple feature but a great way to make this app even better. Get it! Use it! ### 5/5 — Really great app! *2013-09-06* Love it. ### 5/5 — Great App ! *2013-08-17* Very nice flat UI. Nice unit converter/calculator in one. Also great how you can customize the color with much variety. Also has easy to learn gestures. Would like to see a iPad version of the app. ### 5/5 — Great design! *2013-08-15* Like the simple design and great colors! ### 5/5 — BEST ACCOUNTING CALCULATOR *2013-04-25* I LOVE this app!!!! Favorite app of ALL TIME! I use this for serious accounting work, etc. I've been looking for a calculator app like this for my accounting work for a long time, and now I've finally found it! The only suggestion I have is to implement some kind of "clear all" feature to erase all calculation history, such as by swiping up on the history log with two fingers (in addition to the current swipe-to-erase-single-entry gesture). Keep up the great job!!!! =) Hunter ### 5/5 — Simple elegance with full features *2013-03-21* This is so much better than the other conversion apps. Great work on this. ### 5/5 — Nice Clean Design *2013-03-14* Kalc has a very elegant design and does exactly what it sets out to do with great style. I also appreciate how previous calculations are placed in a queue above the main calculation window. Very nice! ### 5/5 — A simple, beautiful app! *2013-03-14* I love the colors and simplicity of the app. Great design! ### 5/5 — Love it!!!! *2013-03-14* Very useful and great when traveling ### 5/5 — Super useful ... and it looks NICE! *2013-03-14* Always need a number/weight/temp translator and this one is so simple and elegant. And I can color-coordinate with my phone case or outfit! ### 5/5 — Excellent design *2013-03-14* This is a handy, simple, and aesthetically pleasing app for unit conversion. I love Kalc! ## Most critical reviews (10 lowest-rated) ### 3/5 — No minus *2019-02-06* No minus on calculator. I wanted to find out what -30 Celsius was in Fahrenheit, can’t do it ### 4/5 — Amazing app, but you took away a key feature *2024-11-20* I’m a big fan of your app and have relied on it for years— However, in one of your more recent updates you removed the option to view last calculations. Now I rely on screenshots of calculations to remember what I’ve calculated in the last. Please bring it back! **Developer response:** Thank you for being a long-time fan of the app! The feature to view your last calculations is still available—swipe left or right on the calculation result in the input area, and you'll see them appear in the list at the top.

I use this for all my accounting work! I’ve been using this since 2013… :) lovely app ### 4/5 — Thanks for the update and tip! *2017-03-17* This is a great little app. Very easy to use. While I still like this app, it needs an update, iOS keeps telling me im the app is being inefficient ### 4/5 — Minus Five Fahrenheit! *2014-01-13* Probably they forgot to make a unit minus; like fahrenheit or celsius minus five! The polar vortex reminded us that we, on some day, need to put a minus before 5.. ### 5/5 — My swiss army knife for travel *2024-05-28* Recent update in unit converter shows feet and inches, which is super useful for measuring my body fat at the gym. I also love this app comes with Easter Eggs customizing colors by swipe up screen and slide palette. ### 5/5 — Minimalism in beautiful design *2024-04-30* This beautiful app materializes minimalism and thoughtful functionality in beautiful design. As a person from metric units country, this is one of app used for almost everyday. ### 5/5 — The best conversion app *2015-08-11* This app is really easy to use! Love it. ### 5/5 — 非常棒！ *2015-05-01* 反正我就是要简单的单位换算，ui也很方便 ### 5/5 — Beautiful and functional *2014-06-07, version 1.3.3* Beautifully designed and built app, a pleasure to use ## Most praised reviews (5 highest-rated) ### 5/5 — Gorgeous *2014-04-08* Gorgeous app! ### 5/5 — Beautiful small app *2013-11-06* Very neat and clever design! ### 5/5 — Such a great app!! *2013-09-27* Good job!
