Callie 2.0 is a major update with a new native iPhone and iPad experience, a cleaner dark glass interface, expanded language support, and a new Currency Converter. New Currency Converter Callie now includes a built-in currency converter powered by public Frankfurter exchange-rate data. Search currencies by code, name, symbol, or common aliases, use common currency shortcuts, swap currencies quickly, and continue converting with cached rates after your first successful update. Expanded Language Support Callie is now localized across 32 language folders, with broader coverage across the app’s native tools and settings. Supported languages include: English Arabic German Greek Spanish French Italian Japanese Korean Portuguese Kinyarwanda Swahili Chinese Hindi Bengali Tamil Telugu Marathi Urdu Indonesian Vietnamese Thai Malay Filipino Hausa Yoruba Igbo Amharic Somali Zulu Xhosa Afrikaans New Native UI and UX Callie has been redesigned around a focused top navigation rail: Money, Convert, Calc, Dates, and More. The interface is cleaner, calmer, and easier to scan on both iPhone and iPad. Calculator Updates The calculator now has a refined Basic and Scientific experience, improved glass-style keys, memory controls, percent, sign toggle, backspace, and scientific functions including trigonometry, logarithms, exponents, square root, π, and e. Money Tools Money tools are easier to access and include Tip Calculator, Bill Split, Currency Converter, Sales Tax & Discount, Unit Price, Fuel Cost, and Loan Payment. Conversion and Date Tools The Convert workspace includes Unit Converter and Percentage Helper. Date tools include Date Calculator and Age Difference for quick date spans and offsets. iPad Improvements Callie now has a more polished iPad experience, including improved layouts and a custom iPad numeric input surface designed to match the app’s glass key style. Privacy and Stability Callie still requires no account or sign-in. Calculator, money, unit, percentage, and date tools run on your device. Currency conversion uses public exchange-rate requests, and typed values are not sent to Callie infrastructure. This update also includes localization audits, input handling improvements, layout cleanup, and general stability fixes across the native Apple app.
