About

Calcora

Features
Read full description

Most calculators give you a keypad and wish you luck. Calcora gives you the 61 calculators you actually reach for — the tip on a bill split four ways, the price after 30% off, the monthly payment on a loan, how much paint a room needs, what your salary is after tax. Every one of them asks for what it needs and shows its working. And it remembers. Save a calculation as a template, name a figure once and use it everywhere, set a reminder for the one you do every month, and find anything you have ever worked out by typing a word from it. And when you need to convert something, 200+ unit conversions, around 160 currencies and every time zone worth knowing are already there. WHAT IS INSIDE • 61 calculators across 11 categories — everyday money, finance, maths, health, construction and trades, engineering, programmer tools, converters, date and time, education, fuel and travel • 200+ unit conversions — 43 units across 7 measures (length, mass, volume, temperature, area, speed, time), every one converting to every other • Around 160 currencies at live rates, kept on the device so they keep working when the signal does not • Time zones for cities across every continent — what time it is there, on any date, with summer time handled for you • A full scientific keypad: trigonometry and its inverses, hyperbolics, logarithms, powers and roots, factorials, memory, constants • A calculation tape where lines have names, and changing one figure updates every total that depends on it • Templates, so a budget you build once is ready the next time you need it • Variables — name a number once and use it on every tape • Chains, where one calculation's answer becomes the next one's question • Reminders on a schedule, so the rent calculation turns up when the rent does • History that remembers everything, searchable in every language the app speaks • Favourites and a Home screen you arrange yourself THE ONES PEOPLE OPEN MOST Tip and split · Discount · Percentage · VAT and sales tax · Loan repayment · EMI · Compound interest · Savings goal · Salary after tax · Currency · Unit converter · Time zones · BMI and body fat · Calorie needs · Due date · Date difference · Age · Fuel cost · Paint and flooring · Concrete · Roof pitch · Ohm's law · Resistor colour · Binary and hex · Bitwise · Statistics · Fractions · Complex numbers · Quadratic · Triangle and circle · GPA · Scientific keypad with memory BUILT TO BE TRUSTED Exact decimal arithmetic throughout. No floating-point drift in a figure about money. Invalid input is refused as you type it rather than accepted and rejected later. YOURS, AND PRIVATE No account. Nothing to sign up for. Every calculation happens on your device and stays there. Calcora works with no signal at all — the one exception is exchange rates, which need fetching once and are then kept on the device. MADE TO FIT YOU • 8 languages, including right-to-left layout for Arabic • 22 themes — a true-black AMOLED, a monochrome palette, and a Signature set made for Calcora • A Home screen whose sections you can reorder or hide, with shortcuts to the tape, your templates and your variables • Every control announced and sized for a real finger, checked automatically One app for all of it — in your language, on your device.

Verdict

The call

The clearest difference is ads: PDFCensor at none against Calcora's shown. Calcora's advantage is update cadence (every 4 days vs fortnightly). On price, in-app purchases, device support and iOS requirement there is nothing between them.
