Truekit: Level, Ruler, Compass

Truekit puts 12 everyday tools in one small app — and every one of them works the moment you open it. No account, no internet, no permission wall. WHY TRUEKIT • Calibrate to real objects. Zero the bubble level on your table, match the ruler to a bank card, set the metal detector's baseline in a clean spot. Readings you can trust, not just numbers. • Nothing gets in the way. The ruler, level, protractor, magnifier and scanner have no ads on the measuring surface, so the ruler runs the full length of your screen. • Asks for nothing up front. The flashlight needs no camera permission. The compass shows magnetic north with no location permission. A tool asks only when it truly needs something, and keeps working if you say no. • The timer keeps running when you leave. It finishes on the clock, not on the screen, and alerts you even if the app is closed. • A home screen widget with your four favorite tools and a flashlight switch — no unlock, no app launch. MEASURE • Bubble level — front/back and left/right angle, one-tap zero calibration, hold to freeze a reading • Ruler — full-screen cm / inch ruler, drag to measure, calibrate to a credit card for true size • Protractor — angle finder: set a reference edge, read the angle between two surfaces • Unit converter — length, weight, temperature, volume (US and UK gallons), area, speed, data. Works offline. SENSE • Compass — magnetic north without location; add true north with one tap if you want it. Tells you when to recalibrate. • Metal detector — magnetic field meter in µT with a live graph and an adjustable baseline • Sound meter — decibel meter with peak hold. A guide, not a lab instrument, and it says so. • Light meter — lux meter with a log-scale gauge from dark room to direct sun EVERYDAY • Flashlight — instant LED torch with SOS, no camera permission • Magnifier — up to 6× zoom with light, for small print and serial numbers • QR & barcode scanner — decoded on your phone, sent nowhere; copy or open the result • Timer & stopwatch — presets, laps, and an alert that survives leaving the app PRIVATE BY DESIGN Everything stays on your phone. Truekit has no server, no login and no tracking of what you measure. Microphone and camera are used only while that tool is open, and audio is never recorded. Free, supported by a few ads that stay out of the measuring area. Light and dark theme, metric or imperial units, available in 16 languages. Looking for a level app, a ruler app, a compass app or a flashlight that just works? Install Truekit once and keep the other eleven in your pocket too.
