## What is Trueline?

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. No subscription, no sign-in, and nothing leaves your phone.
