It should be resolved in the latest version of the app. Please confirm that it is now working properly, and let us know if you have any other questions. ### 4/5 — Useful with some drawbacks *2014-07-17, version 1.02* Quick entry to convert to many forms. The biggest drawback is that it takes over the audio even if the key clocks are set to none so you can't listen to music while using this app. Does not allow little endian format for 16bit hex. Would also be useful to have option to space every two bytes instead of four. ## Frequently asked questions about iConvert Hex Decimal Binary ### What number formats does iConvert Hex Decimal Binary support? iConvert Hex Decimal Binary supports binary, hexadecimal, and decimal formats.
