【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.

Verdict
The clearest difference is in-app purchases: FastCalc lite at none against Calculator+'s 2. Calculator+'s advantage is update cadence (every 5 days vs every 5 months) and iOS requirement (16.0 vs 26.0). On price, ads and device support there is nothing between them.
