Unit Converter & Tool

160 tools in one app. Unit converters, calculators and everyday utilities that work offline, with no ads, no accounts and no tracking. Most tool apps ask for permissions they never use. This one requests two: internet, only to fetch live currency rates, and vibrate, for the timer and metronome. Nothing else. No location, no camera, no microphone, no contacts, no files. Nothing you type is collected, uploaded or sold. ━━━━━━━━━━━━━━━━━━━━━━━━ 73 UNIT CONVERTERS ━━━━━━━━━━━━━━━━━━━━━━━━ Everyday • Weight, Length, Speed, Area, Volume, Temperature • Currency with live exchange rates, and dated offline rates when you have no signal • Cooking measurements, Fuel consumption, Metric prefixes Engineering and science • Pressure, Force, Torque, Density, Acceleration, Angular velocity • Heat, Heat capacity, Specific heat, Heat flux, Heat transfer • Viscosity, Flow rate, Concentration, Permeability, Surface tension • Astronomy, Lumber volume, Specific volume, Inertia, Sound Electrical • Power, Current, Energy, Resistance, Capacitance, Inductance • Charge, Conductance, Conductivity, Potential, Resistivity • Field strength, Linear, Surface and Volume charge density Also: Computer storage and resolution, Light and luminance, Magnetic flux, Radiology units, and 9 clinical converters for laboratory reference. ━━━━━━━━━━━━━━━━━━━━━━━━ 45 TOOLS ━━━━━━━━━━━━━━━━━━━━━━━━ • Compass, Bubble Level, Protractor, Ruler • Scientific Calculator, Notes, Text Tools • Stopwatch, Countdown Timer, World Time, Time Zones, Military Time • Date Calculator, Age Calculator, Calendar • Password Generator, Dice and Random Picker, Counter • Resistor, Capacitor and Inductor colour codes, Logic Gates • Wire sizes in AWG and SWG, Periodic Table with all 118 elements • HEX to RGB, Aspect Ratio, Morse Code, Cryptography • Shoe, Clothes, Hat and Ring size charts • Electricity Bill, Energy Consumption, Fuel Cost, Jewellery Price • BMI, Grade Calculator, Square Footage, Metronome, Battery Status ━━━━━━━━━━━━━━━━━━━━━━━━ 20 FINANCE CALCULATORS ━━━━━━━━━━━━━━━━━━━━━━━━ • Mortgage, EMI, Car Loan, Loan repayment • Compound Interest, Simple Interest, CAGR, ROI • Present Value, Future Value, Annuity, Perpetuity • Retirement planning, Stock returns, Fixed Deposit, Certificate of Deposit • Percentage, Discount, Tip, Service Tax ━━━━━━━━━━━━━━━━━━━━━━━━ 22 MATHS CALCULATORS ━━━━━━━━━━━━━━━━━━━━━━━━ • Linear, Quadratic and Cubic equation solvers • Expression Evaluator, Statistics, Permutations and Combinations • Prime Factors, GCD and LCM, Decimal to Fraction, Number properties • Number bases and Binary, Roman Numerals, Number Series • Ratio, Proportions, Area, Volume, Surface Area, Perimeter ━━━━━━━━━━━━━━━━━━━━━━━━ WHY THIS ONE ━━━━━━━━━━━━━━━━━━━━━━━━ • Works offline. Only the currency converter needs a connection, and it falls back to dated offline rates and tells you when it does. • Two permissions. Not fifteen. • No ads, no popups, no sign-up, no subscription prompts. • Nothing is collected. No analytics, no advertising IDs, no crash tracking. • Search across everything, and switch any tab between grid and list. ━━━━━━━━━━━━━━━━━━━━━━━━ PLEASE NOTE ━━━━━━━━━━━━━━━━━━━━━━━━ The clinical unit converters and the BMI tool are for reference and education only. They are not medical devices and must not be used to diagnose or treat any condition. Check results against your laboratory's own reference ranges and speak to a qualified healthcare professional. The finance calculators are educational tools, not financial advice. Confirm any figure with an authoritative source before relying on it. The on-screen ruler and protractor should be calibrated against a known object before use, since screen sizes differ between devices.
