Trueline turns your iPhone into a level that behaves like a real instrument — quiet, readable, and honest about what it measures. Free: • Auto-switching modes — on edge or plumb you get a vial with a signed degree readout; laid flat it becomes a 2-axis bullseye surface level • Read in degrees, slope %, or roof pitch (rise per 12) • One-tap calibration • HOLD freezes a reading you can't see from where you're standing • ZERO for relative angles — the angle between two surfaces • Haptic snap and a green edge glow the moment you're level • Fully offline, no account Pro — one payment of $6.99, no subscription: • AR laser level: project gravity-true level and plumb lines onto the wall and hang a whole row of frames in one pass • Named angle presets — 4/12 and 6/12 roof pitch, stair rake, 2% drainage • Precision tolerance down to ±0.1° • 5 instrument themes • No ads Pay once, yours forever.
