## What is Unitto?

Unitto is a fast, fully offline unit converter built for anyone who needs a clean answer without digging through menus. Type a query like "5 km to mi" or "98.6 f to c" and get an instant result — or browse by category and pick units by hand. Runners convert km to mi and km/h to mph mid-run; cooks convert grams to cups; travelers convert kg to lbs and celsius to fahrenheit before a trip.

Every conversion happens on your device — no network calls, no accounts, and no ads. Nothing about what you convert ever leaves your phone.

Included from the start:
– Natural-language quick convert: type "5 km to mi" and get the answer immediately
– Six core categories: length, weight, temperature, speed, volume, and area
– Favorites for the conversions you use every day
– Recent history so you never lose a result

Unitto Pro (one-time purchase, unlocks forever) adds:
– Batch convert: paste a whole list and get every result at once
– Seven extra categories: time, data storage, pressure, energy, power, angle, and fuel economy
– Extra precision on every result
– Unlimited favorites

No subscription. No accounts. No ads. Just a fast, accurate converter that works the moment you open it — even with no signal.
