About this app

Calculators used to be fun. Tabula brings that back. Tabula is an everyday calculator remastered as the machines you grew up with. Pick an era, from a cream 80s desk calculator to a chunky handheld console, a neon synthwave dashboard, or an amber terminal, and do your daily math on something with personality. Underneath the nostalgia is a fast, modern calculator built for real life: split a dinner bill, add up a grocery run, check a budget, or work through numbers step by step without losing your place. FEATURES * Nine era-accurate themes, each tuned for light and dark mode * Editable equations: tap any operator in the expression to change it, no retyping * History: every calculation saved, tap any past result to pick up where you left off * Paper tape: your whole session on one receipt-style ribbon you can copy and share * Tip mode: tip and per-person totals without leaving the calculator * Memory register: classic M+, M-, MR, MC for chained calculations * Constants library: insert pi, e, phi, the speed of light, and more with one tap * Home screen widgets: last result, history, memory, and theme showcase * Live Activities: keep your running calculation on the Lock Screen * Matching app icons so your home screen fits your vibe * Haptics, optional sound effects, and adjustable decimals and rounding PAY ONCE, OWN IT FOREVER Tabula Pro is a single one-time purchase.
