Just found this handy iPhone application for all the DIY handymen out there.
The “iHandy Carpenter” turns your iPhone into a Plumb Bob and a Level in one go.
Here is the info from the website:
– THE PLUMB BOB, SURFACE LEVEL AND BUBBLE LEVEL BAR
Calibrate it first before any serious usage!
– USE THE PLUMB BOB TO MEASURE THE VERTILITY OF A WALL
Two ways to test the verticality of a wall:
1. Put your iPhone back-to-back onto the wall you measure (Recommended).
If the shadow of the plumb bob is on X axis (y equals zero), it then indicates your wall is perfectly straight and vertical to the ground. Please note that in this way the reading of “x” does NOT have to be zero.
The back of 3G iPhone is not totally flat. But it’s accurate enough just to use the flat part of your 3G iPhone.
2. Put one edge of your iPhone on the wall you measure.
If the shadow of the plumb bob is on Y axis (x equals zero), it then indicates your wall is perfectly straight and vertical to the ground. Please note that in this way the reading of “x” does NOT have to be zero.
– HOW TO MEASURE THE SLOPE OF A SURFACE
A few ways to measure the slope of a surface:
1. Use the Surface Level (Recommended).
Put your iphone onto the inclined surface (The edge of iPhone should be in line with the slope direction of the surface. To verify this, just to check whether the reading of “y” is around zero).
The reading of “x” is the slope angle of the measured surface.
2. Use the bubble level bar
Put one edge or back of your iPhone stick to the inclined surface (The edge of iPhone should be in line with the slope direction of the surface).
The reading is the slope angle of the measured surface.
If the surface is almost vertical to the ground, we suggest that you use the plumb bob tool to measure the surface instead.

The iHandy Carpenter is available in iTunes App Store.
Been using this app for a few years now, works a treat. The self setting function is great and highly useful.
