No keyboard when trying to name a new mode. You have to use the camera to read the text?! ### 1/5 — Disappointing *2025-05-12* The most recent update has killed this app. I use this with the ArcX Ring while preaching every week. Unfortunately there is no longer a way to adjust settings for this. New app does not work properly. Disappointing. The ArcX ringing was not an inexpensive purchase. ### 1/5 — Too many major bugs to even list. *2023-01-31* What a shame. Finally somebody made the product I’ve been waiting years for, but the software is absolutely killing it. (In a bad way.) Some of the bugs are so major and obvious that it leaves me wondering if the project took too long and fell apart, and they just launched it anyway. ### 3/5 — Doesn't work with dark mode *2023-01-19* some text is using absolute color values instead of relative, so dark mode causes some menus to be blank ### 2/5 — Buggy App *2023-01-15* Same problems as above review. Type screen does not disappear and no way to change functions. ### 3/5 — buggy keyboard and drop down menus *2023-01-12* just downloaded the app to try out and the keyboard glitches and stays on screen after I type in a name for a new mode. Have to close the app and reopen to exit the keyboard. The drop down options for creating a new mode also don’t show the text. You can still feel feedback and hear scrolling through options, plus you can see the option name after it’s selected, but the drop down menu is blank. It’s almost as if it’s white text on a white background and it’s just not visible. ## Frequently asked questions about ArcX ### What is ArcX? ArcX is a companion app for the ArcX smart ring.
