### 5/5 — Works

*2026-01-26*

Edit: the bug was fixed and this app is great!

Cool calculator, but for whatever reason, it doesn’t display the numbers for the current number system you’re using. Example: if you’re in decimal mode and type 1234, it’s just blank on the DEC row, but does convert into the other number systems.

**Developer response:** Hello, Thank you for your feedback! That issue is happening when dark mode is enabled in the device, as a workaround you can try using the app with light mode. The next release will fix this issue, we will let you know when the new version is live!
