Mathify is a fast, focused calculator for iPhone and iPad. Ask the AI calculator a question in plain language or open a dedicated native calculator for math, finance, conversions, dates, fitness, business, and more. Native calculations run on-device, update as you type, and keep long expressions easy to review without taking over the screen. AI answers show the formula, working, assumptions, and a clear result. Your history stays on your device. The app ships without ads, accounts, tracking SDKs, or blog content. Available in the same 28 languages as Mathify web; the AI calculator answers in your language, and some calculator field labels are still English while translation continues. General wellness estimates are clearly marked as educational planning tools and are not medical advice. Clinical dosing, medication, vaccination, blood-alcohol, drug half-life, and gambling tools are not included in this launch.
