Hi Product Hunt! I’m the indie dev behind Calculator AiO. I built this because I was tired of juggling a basic calc, a separate unit/currency app, "photo solve"-tools, and even math handwriting. * One app, many tools: fast keypad with history/undo/redo, unit + currency conversion (live rates with offline fallback). * Smarter solving: snap a photo to get step-by-step help, or chat with a math assistant for clear explanations. * Write & graph: handwriting recognition on a clean grid, plus smooth graphing with pinch/zoom and inspection. * Private by design: no ads, minimal permissions, optional Face ID vault for sensitive images/videos. * Delightful to use: themes, haptics, adjustable fonts, and a layout tuned for speed. Thank you!
