This is a simple app that allows you to measure the effects of gravity. It displays how many G's you are experiencing and also what the gravitational acceleration is.

Gravity varies due to many things. The most common factors that change the force of gravity is:
The position of the sun and moon
The type/density of rock found in your area

Gravity Meter now shows the average gravitational acceleration of major cities around the world.

Gravity Meter now has faster data collection on startup and adjustable accelerometer accuracy. The data measured by the accelerometer can be adjusted to be extremely accurate or to have a fast response time.

For more features, check out Gravity Meter Pro.

Does what it says on the tin

This is a good free app as long as you just need a basic no-frills read-out of your local g. What I would love to see would be an x-y-plane g-force meter too, and a graphical display of g against time, so I can see how many Gs I pulled rushing to work or school in the morning, or at least a read-out of Max G Reached or something. Combine that with a prettier, more graphical display and you've got an app I'd eagerly pay for! Nice one!

Awesome! 100% real!

A cool app for the household scientist. I can tell it is real because increasing centrifugal force (spinning around) causes the meter to go up.

Works great, but it would be neat if it measured g forces while driving.
