Ever felt the need to urgently check the leveling of a surface but didn't have a spirit level handy or lazy to download an app? Then this is just for you.
If you Google 'bubble level' or 'spirit level' on your phone's browser or the Google Search app, you will instantly get a spirit level that works with the magnetometer on your phone, assuming it has one. You can keep a device flat on its back to check overall level or sideways to check horizontal tilt.
Do keep in mind your phone's magnetometer needs to be properly calibrated for this to work and that any bumps on the back or side (cameras, buttons) will automatically unlevel the phone and mess up your reading. For any serious work you should be using an actual spirit level since the ones on phones could go whack for a number of reasons but for a quick, casual check this should work fine.
You have a valid point there, sadly not all of us can afford 24/7 mobile internet. I use Swiss Army Knife app with tons of tools. And yes I even use it like once per year for bubble level measurement :)
I know, but any bubble level app uses the accelerometer instead, using the magnetometer wouldn't even provide a fun toy if you aren't under perfect conditions.
i really dont expect much on isheeps comments...but dont you guys ever read the article?
