CalcMate - Everyday Calculator

CalcMate is the calculator for everyday life. Alongside a basic, scientific, and fraction calculator, it brings together the practical tools you reach for during an ordinary day — at the shop, in the kitchen, at your desk, or around the house. It works without an internet connection, shows no ads, and doesn't track anything.

Made for daily tasks
Split a restaurant bill and add a tip, check how much you really save in a sale, convert a recipe for more guests, work out a monthly loan payment, find out how many days until an event, or resize measurements for a small home project. Whatever the day brings, the right tool is a tap away.

Calculators
Do quick everyday math, or switch to scientific mode for powers, roots, trigonometry, logarithms, factorials, and constants like pi and e — in degrees or radians. The fraction calculator shows each step of the solution, which helps with learning and checking your work. Memory keys and an auto-resizing display keep things easy to read.

Converters
Convert between units across 17 categories, including length, mass, temperature, area, volume, speed, data, pressure, energy, and power. A currency converter covers 58 currencies, with rates kept on your device that you can adjust yourself.

Everyday tools
- Shopping: percentages, discounts, tips and bill splitting, tax/VAT, and price-per-unit comparisons
- Money: loan repayments and simple or compound interest
- Dates: your age, the gap between two dates, adding or subtracting days, and a world clock
- Home and kitchen: recipe scaling and carpentry inch fractions
- Health (for reference): body mass index, daily calories, and body-fat estimates
- Study and work: geometry, equations, number bases, GCD and LCM, prime numbers, random numbers, permutations and combinations, GPA, averages, ratios, and Ohm's law with resistor networks

History and backup
Your calculations are saved automatically and grouped by day, so you can look back at what you worked out. Export them, or make a full backup and restore it later.

Make it your own
Choose from eight color themes, switch between light and dark, turn on a subtle particle effect, and enable haptic feedback. A search box helps you find any tool in seconds.

Home screen widget
Keep a working calculator on your home screen for the numbers you check throughout the day — no need to open the app.
