XCalc.io Calculator + History: feedback wanted on Low Vision Mode and VoiceOver

Hello everyone,

I’m Mihai, the developer of XCalc.io Calculator + History for iPhone and iPad.

XCalc began with a simple promise: numbers should never be hard to see or use. Part of the inspiration came from a family member with low vision, so readability shaped the app from the beginning.

The feature I would most value your feedback on is Low Vision Mode. When enabled, it uses larger and bolder text, stronger contrast, and less visual emphasis on operation-key fills. Button shapes can be adjusted separately.

If you try XCalc, I would especially value your impressions after using it with Low Vision Mode turned off and then on. Does the mode make the numbers and controls easier and more comfortable to see and use? Please also tell me if anything remains too small, unclear, or difficult to distinguish.

XCalc also supports common VoiceOver workflows, including entering a calculation, locating and copying the result, switching calculator modes, and using History and Memory. Feedback on labels, navigation, actions, or anything confusing would also be very helpful.

XCalc is free to download, contains no ads, and offers XCalc Pro as an optional one-time purchase with no subscription.

I contacted the AppleVis Editorial Team before posting and received permission to ask for feedback here. I’ll follow the discussion and take constructive feedback seriously.

Thank you for taking the time to try XCalc.io and share your thoughts.
