## What is PlumbLine?

Is that wall truly vertical? Is that shelf actually level? Hold your iPhone against the surface and PlumbLine tells you instantly — no bubble to squint at, no numbers to read. The whole screen turns green the moment it's straight.

HOLD IT, DON'T READ IT
- Press the back of your phone flat against a wall, post, door frame, shelf or picture frame
- A big target view shows the tilt front-to-back and left-to-right at a glance
- The screen flashes green with a beep and a tap the instant the surface is true — so you can adjust with your eyes on the wall, not the phone

VERTICAL AND HORIZONTAL, AUTOMATICALLY
- Put the phone upright against a wall and PlumbLine checks plumb (vertical)
- Lay it flat on a shelf and it checks level (horizontal)
- It senses how you're holding it and switches — you never pick a mode

MADE FOR STRAIGHTENING THINGS
- Hanging pictures and shelves, setting fence posts, aligning door frames, leveling furniture and appliances
- Set your tolerance: strict, standard or rough — the color verdict follows it
- Zero it against an existing surface to match a new one to it

SMALL TOUCHES THAT HELP
- Hold the reading to freeze it, then step back and check a spot you can't watch
- Save measured surfaces with a name to compare them later
- Choose degrees, percent slope or mm/m

PRIVATE AND SIMPLE
- One-time purchase. No subscription, no ads, no account
- Works fully offline. Nothing you measure ever leaves your device

PlumbLine is a planning aid. For precision construction, use a calibrated tool.
