Ratora

Ratora converts. Every unit family is free, forever, with no ads — and the answer appears as you type, with nothing covering the keypad. A conversion is an equivalence, not a transformation. Ratora draws it that way: your value and its answer sit on either side of a beam, held level, with the exact relationship engraved between them. FREE, FOREVER • 14 unit families: length, mass, volume, temperature, area, speed, time, data, pressure, energy, power, angle, fuel economy and cooking • Unlimited conversions — no counters, no interruptions, no "watch an ad to continue" • Multi-convert: one value shown across every unit in its family at once • Fraction entry and a tape reading for imperial lengths (3 ft 5 5/8 in) • A cooking room that knows flour, sugar, butter and rice do not share a density — one cup of flour is 125 g and one cup of sugar is 200 g, and Ratora says so • 25 recent conversions and 8 pinned pairs • No ads. No tracking. No account. RATORA PRO — THE RATES LAYER Unit factors are constants: an inch will be 2.54 cm forever, and that half of Ratora never needs to be paid for. Exchange rates are different — they have a date. Pro is the part that carries it: • Currency for 200+ codes, from European Central Bank reference rates • Published once each working day, around 16:00 CET — and every screen states the date the rates were published and how old that is • A dated offline cache that still answers on a plane • A 30-day trend per pair • Home Screen and Lock Screen widgets • Custom units you define yourself • Unlimited pinned pairs and 250 recents Ratora does not claim a real-time or market price, because it does not have one. It shows you the last published day and tells you how old it is. PRO PRICING Ratora Pro is $4.99 per month or $39.99 per year, with a 7-day free trial.
