Convrtr

Fast, clean and fully offline. Convrtr converts everything from everyday units like length, weight and temperature to specialist ones you won't find elsewhere — water hardness, flow rate, blood sugar and fuel efficiency. Type in either field and the other updates instantly. Switch between units with a tap, save your most-used conversions as favourites, and use quick-value buttons to jump straight to common numbers. Works with zero signal once installed. No ads, no account, no nonsense.
