75+ converters across 10 categories. Plus 14 sensor-powered tools — AR distance, GPS speed, sound meter, spirit level, and more. One beautiful app. Free, offline, private.
From everyday length and weight to scientific frequency, electrical capacitance, and live currency rates. Search across all 75+ converters in one tap — favorites, history, and color-coded categories built in.
Color conversion across HEX, RGB, and HSL. Number bases. Roman numerals. Mortgage calculators. Paper sizes. Wire gauges. The categories you only realize you need when you really need them — already built in.
Pro tip: Tap any result to copy it. Tap and hold for unit info.
The sensors are already there — Measuro turns them into 14 dedicated tools. AR-powered distance and area, GPS speed, ambient sound and light, magnetic field, atmospheric pressure, motion-tracked steps, and more. No extra hardware. No setup.
The built-in quiz turns unit knowledge into a game. Pick a difficulty, race the timer, and earn streak bonuses for consecutive correct answers. Nine distinct question types — text, sliders, bar matching, sorting — keep every round fresh.
Designed around respect — for your time, your battery, and your data.
Most features work offline. Conversions, history, and tool data live on your device — never on a server.
No sign-up, no login, no email collection. Open the app and use it.
Camera, microphone, location, and motion are only requested by the specific tool that uses them — never in the background.
Essential converters and all measure tools are free. Premium unlocks pro categories and removes ads.
