Women love it. ### 5/5 — Good job! *2011-03-27, version 1.4* Thank you! Very helpful. ### 5/5 — Works *2011-03-23, version 1.4* The only thing that it lacks is a power button but that may be my own incompetence in using technology. ### 5/5 — Only coverts from decimal to other form. *2011-02-01, version 0* It would be nice to be able to type something in in hexadecimal for example and view it's decimal or binary value. Otherwise, at least to me, this app seems kind of pointless. ### 5/5 — Awesome calc *2010-05-26, version 0* Love this calc. Other calculaters cost money and they don't even have as many options as this one. ### 5/5 — There really is an app for everything *2010-02-18, version 0* Love it, and it's free ### 5/5 — Great *2009-10-29, version 0* It's just great.

Program crashes instead, plz fix. ### 2/5 — Good idea, poor execution *2010-07-30, version 0* No way to enter A-F for hexadecimal values. ### 3/5 — No letters *2012-10-19, version 1.4* It converts from decimal great, but it lacks the ability to enter letters in anything base eleven or higher. ### 3/5 — Green11 *2011-05-27, version 1.4* Good app and useful for students ### 3/5 — Good, but needs a tweak *2010-05-30, version 0* Suppreses the first 0 when converting to binary. ### 3/5 — Práctica y Sencilla *2009-02-24, version 0* Bastante buena para lo sencilla que es Gracias ### 4/5 — Simple, useful. *2015-08-13, version 2.0.6* Simple to use, does what it says, although I'm struggling to see how to convert other than decimal to, e.g binary. ### 4/5 — Works great *2012-09-15, version 1.4* An improvement would be the ability to enter something other than decimal in upper register so you could directly convert hex to binary, etc. ### 4/5 — Very useful! *2009-02-16, version 0* A simple multi-base calculator/converter that's great for engineers like myself. ### 5/5 — Works perfect! *2023-01-30, version 3.2* Perfect learning tool to check the work while learning these number systems, thanks for making this! ## Most praised reviews (9 highest-rated) ### 5/5 — That’s Numberwang! *2021-06-12, version 3.2* Handy for keying in a number (in any base from binary to hexatrigesimal!) and flipping back in forth among bases. Very useful, thanks! ### 5/5 — 1010000001110101110 *2018-05-18, version 2.0.7* That's "nice" in binary. This is a good app! ### 5/5 — Works as advertised! *2015-07-04, version 2.0.6* Been studying how to convert IP Addresses to Binary. Verifying my work with this app and it works terrific. Quick, easy and accurate! ### 5/5 — Rz *2014-05-01, version 2.0.3* Nice app! ### 5/5 — Just right *2014-02-19* Many more features and better presented than any of the others. ### 5/5 — Awesome. It just works. That's it. *2012-08-28* This is exactly what I need. ### 5/5 — Very handy calculator! *2012-08-12, version 1.4* Design of interface is clever and easy to use. I really like the flexibilty of quickly switching to the different bases using the selection wheel. Only upgrade I would like is to be able to switch base in top display from decimal. Perhaps add that option to the info window so it doesn't clutter the nice, clean interface of the main window. ### 5/5 — Just great *2012-01-25, version 1.4* Being able to enter hexadecimal values is sweet! Helps with circuits homework like none other. People below say you can't enter hexadec values, but you can. Just be smart ### 5/5 — Life saver... *2012-01-17, version 1.4* It works, it's free, I'm happy :D --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
