Sie funktioniert einwandfrei, kann auch mit negativen Zahlen und 64-Bit-Werten korrekt umgehen und ist vielleicht der beste Hex-Rechner, den ich kenne. Für Softwareentwickler supernützlich. ### 5/5 — good app!!! *2015-04-21, version 1.1* really good one !!! ### 5/5 — Exzellent *2014-03-03, version 1.1* Einfach und gut.

Could not use it at all until after I restarted the phone. ### 1/5 — Deadware *2015-09-27, version 1.1* Does not work with iOS9 ### 3/5 — Good but no leading 0s for bin *2019-08-18, version 3.1* I really like that it’s a lightweight app with no ads, but it doesn’t seem to allow leading zeros when working with binary. That’s a deal breaker for me :( Please add :) ### 3/5 — Limited length *2012-05-30, version 1.1* Only does upto 8 hex chars. Rats! ### 4/5 — Great app, need to be updated *2026-06-14, version 3.3* This app needs to be updated to accommodate the newer IPhone front facing cameras. the app display is partially being blocked by the front facing camera.. just needs to be a little lower is all. ### 4/5 — Portrait view only *2022-06-12, version 3.3* The functionality and user interface is really nice. Unfortunately it doesn’t work in landscape mode, so it is awkward to use on an iPad unless you rotate the screen. ### 4/5 — Thanks *2012-07-30, version 1.1* Much appreciated! ### 4/5 — Simple binary/hex calculator *2012-06-06, version 1.1* Good calculator, does what it says. ### 5/5 — Programmers Swiss Army Knife *2025-07-03, version 3.3* The only calculator that can correctly handle unsigned and signed interpretations and calculates correctly within the value range. And that means a lot. ### 5/5 — Perfect tool *2025-03-06, version 3.3* I use for 7-bit calculations for MIDI SysEx data. Just one feature is missing, a quotient of MODulo. ## Most praised reviews (8 highest-rated) ### 5/5 — I love this app *2020-07-21, version 3.3* I love this app. Works great and is well supported. So useful. Thanks! ### 5/5 — Мне нравится *2020-07-21, version 3.3* Просто, понятно, делает то, что мне нужно. Хороший калькулятор. Гонять значения туда-сюда по системам очень удобно. Рекомендую. ### 5/5 — Tolle App *2020-06-05, version 3.2* Tolle App, perfektes Design. Benutze sie regelmäßig. Danke ### 5/5 — Brilliant! *2019-03-06, version 3.1* I still program old 8 but micros using machine code so I searched and searched for a good hex calculator that specifically could be altered to 16 bit range only. Not only is this the only one that allowed this feature, it is also the best looking and easiest to use - in my opinion! ### 5/5 — 64-bits *2017-03-14, version 3.0* Appreciate the 64-bit support. ### 5/5 — Useful app and no ads - 5 stars *2016-11-03, version 3.0* Good hex/dec/binary conversion calculator with no ads. 5 stars.
