Plumb is a precision bubble level that looks and feels like the real thing — machined bezel, genuine spring-damper physics, and a vial with real fluid optics. Check level, plumb, any angle, or a whole surface at once. No ads. No account. No tracking. The bubble moves with genuine spring-damper physics. The bezel looks like machined rubber. The vial renders with real fluid optics. When you hit level, the screen flashes, a tone fires, and the phone vibrates — all at once, so you can feel it without looking. LEVEL TAB The main vial reads roll in portrait or landscape. Lock orientation from the toolbar — portrait, landscape left, landscape right, or auto. Lock a reading to free up your hands. Calibrate to any known flat surface with one tap. SURFACE TAB A bullseye level checks both axes simultaneously. Perfect for countertops, appliances, equipment, and anything that needs to be flat in every direction at once. ANGLE TAB Dial in any target angle — 45°, 22.5°, a custom pitch, or a grade percentage — and get live feedback as you approach it. Great for trim work, ramps, crown molding, roofing, and drainage slopes. SIX DISPLAY MODES Choose how angles are shown — degrees, percentage, mm/m, pitch (X.X:12), or in/ft. Each tab has its own independent display mode. Tap any readout to cycle through options. WORKS EVERY WAY YOU HOLD IT Portrait, landscape left, landscape right, face-up, face-down — Plumb reads correctly in every orientation automatically. No mode to switch, no setup required. HOLD Freeze any reading with one tap, one volume button press, or the Action button. Press again to release. A haptic confirms when hold is activated or released. FEEDBACK THAT KEEPS UP WITH YOU Tone — pitch rises as you approach level, fires a clean confirm when you hit it Flash — the camera flash pulses on level, useful in dark spaces Haptic — a firm tap through the phone the moment you're on target NIGHT MODE A dedicated all-black theme with deep red vial and glow ring. Designed for attics, crawl spaces, and low-light conditions where a bright yellow screen is a liability. SIX THEMES Yellow, Red, Black, Sky Blue, Orange, and Night mode. CALIBRATION Per-orientation calibration profiles. Calibrate portrait, landscape left, landscape right, and flat independently. Reset any profile individually or all at once. NO ADS. NO TRACKING. Plumb does one thing and does it right. Nothing phones home. Nothing asks for your email.
