• Blood Sugar now double-checks unusual readings — if you enter a value with a decimal the way it appears on your meter, the app asks whether you meant the alternate unit before converting or saving to your log • Added traditional Japanese shakkanhō units for length (rin, bu, sun, shaku, jō, ken) and area (tsubo), using Meiji-era metric-fixed values • Ring Size now includes UK letter sizes (A–Z with half sizes) alongside US, EU, Swiss, and other standards • New contact form in Settings → About pre-fills your app and device info so support requests get answered faster
