Retro Numpad

Retro Numpad brings back the feel of a real desktop calculator — a warm, matte case, a glowing LCD readout, and number keys that actually click when you press them. Built for fast, everyday math: addition, subtraction, multiplication, division, and percentages, with chained operations so you can work through a full expression without losing your place. The display keeps your last expression in view above the current result, just like a physical calculator's tape. FEATURES — Full arithmetic: +, −, ×, ÷, % — Chained operations (2 + 3 × 4, entered left to right) — Decimal entry, backspace, and all-clear — Clear "Error" state instead of a crash on divide-by-zero — Light and dark mode, each with its own tuned palette — Haptic feedback and a physical key-press animation — No accounts, no ads, no tracking
