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. ### 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. ### 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 ### 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 :) ### 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. ## Frequently asked questions about CP HexCalc ### What number systems does CP HexCalc support?
