[Public-List] Digital level for iPhone

I used the phone app for a similar purpose, which was to get the dead-rise 
angle for the mounting location on the depth-sounder transducer so I would 
shoot straight down rather than at an angle. It was the area aft of the port 
bulkhead and was 22 degrees.

Subject: [Public-List] Digital level for iPhone

Couple of weeks ago several people expressed an interest in how I replaced 
my toe rails with wood bulwarks.

Yesterday I accidentally came up with a better way to measure the deck 
camber to fit the bottom of the bulwark to the curved portion of the deck.

I downloaded a free digital carpenter's level onto my iPhone!  Discovered 
there are over 100 free level apps to choose from.  I selected one that has 
a digital readout in radians and degrees- good to 1/10th of a degree. 
Simply lay the phone on the deck, it reports the correct deck angle to 
tenths.  Huge improvement over the manual protractor I used. Much more 

BTY, I just used this app to fix my engine alignment.  Was having on going 
troubles dialing the coupling and transmission flange in the last 
thousandths, so laid the phone on the engine and squared it a bit 
athawrtshups  which took out the high centering on the right side, then on 
the shaft and observed it was12.7 degrees coming out of the hull.  Finally 
laid the phone on the engine manifold and tranny case (same angle) which was 
12.1degrees.  So after cranking the front jack screws up three turns to 
12.6, the coupling slipped on the flange with nary a sound.  Two finger slip 
fit after weeks of ridiculous head banging!

Measured the clearance at less than 2 thousandths.  Fantastic results for a 
simple little app.
