  • Target Android 14 (API level 34) to comply with Play store policy.


  • Add: Missing languages: Azerbaijani (Latin alphabet), Burmese, Filipino, Punjabi (Shahmukhi and Gurmukhi alphabets).
  • Add: About screen shows current locale at the bottom.
  • Change: In addition to the decimal separator of the current locale (usually either comma or fullstop), the user may also use comma (,) and fullstop (.) and Arabic comma (ูซ) to input decimal numbers. This helps with some languages where the numeric keyboard does not allow the locale’s default decimal separator. But the user cannot use a character as a decimal separator, if this character is also the grouping (thousands) separator of the current locale. This avoids confusion while maximizing accessibility.
