What's New Ad-free: UnitFlowPro no longer contains ads or in-app purchases. (Optional line: keep it only if this is the first release without them.) Better on iPad: a wider category sidebar so long names like "Numeral Systems" fit, and a tidier, centered layout on larger screens, including onboarding. Larger text sizes: headers, buttons and unit rows now stay readable and uncluttered at the largest accessibility text sizes. Easier to tap: the header, reorder, favourite and info buttons now have larger touch areas. Smarter Siri and Shortcuts: requests like "12 in to cm" now work, and "20 C to F" and "kelvin" are understood. More accurate calculator: currency in the expression calculator now uses live exchange rates, and same-unit division such as 10 ft / 2 ft returns a plain number. Better copy and paste: values like "1,234 kg" from your clipboard are recognised, and "B" (byte) is no longer confused with "b" (bit). Cleaner history sync: iCloud no longer creates duplicate history entries when you use more than one device. Share Image fix: shared conversion images are now readable when you share from Dark Mode. Stability: fixed crashes from very large numbers in the tip, pace and 3D-printing calculators and the aspect-ratio tool. Smaller fixes: the start category can no longer appear to be hidden in Reorder Categories, and colors in the Color Converter now show correct values.
