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:
Latitude
Altitude
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.
