【Quick Calc】 brings five calculators together in one app: everyday math, scientific functions, AI photo solving, currency conversion and unit conversion, all in a clean interface that is ready whenever you need it. Basic & Scientific Calculator Handle everyday sums on a clear keypad, or switch to trigonometry, powers, roots, logarithms and factorials when a problem calls for them. Every calculation is saved to history, so you can review or copy results at any time. AI Photo Solving Snap a photo of a math or word problem, frame the part you need, and get a step-by-step solution with the final answer. Ask follow-up questions, or turn on deep thinking and web search for more thorough explanations. Photo and Data Handling AI Photo Solving uses photos only when you choose an image of a problem. The selected image is uploaded to our backend and AI service for processing so we can return a solution. Quick Calc does not provide photo-library browsing, album management, cloud-drive storage, or automatic scanning of your photos. The app accesses only the image you select for this feature. Live Currency Conversion Convert between major currencies with up-to-date exchange rates, swap currencies in one tap, and find any currency by name or code. Unit Conversion Convert length, area, volume, weight, temperature, speed, time and data units in moments, with searchable unit lists and a saved conversion history. Personalized Experience Choose from themes, backgrounds and key sounds, adjust decimal places and thousands separators, and have results read aloud. Quick Calc keeps all your everyday calculations in one place. Download it and start calculating with ease today.
