Every category is now free. • All 32 unit categories and the engineering tools are unlocked. No ad to watch, no unlock timer. • Now properly translated into 33 languages. Unit and category names were showing in English everywhere; they are localised throughout. • Decimal commas and points now follow your device region. Entering 1,234 in a comma-decimal locale reads as 1.234, not 1234. • Devanagari and Arabic-Indic digits are accepted. • Faster category lists and search. • History saves one entry per conversion instead of one per keystroke. • Ad privacy options added to Settings. • Requires iOS 18.
