Time Warper

We use Albert Einstein’s theories of special and general relativity to work out how the rate at which you age is affected by gravity and the speed at which you move about.The app calculates the difference in the rate at which time flows for you here on Earth and for a hypothetical clock floating in space above the North Pole far from the pull of the Earth's gravity.
Imagine an astronaut floating alongside the clock - the app shows how quickly or slowly you're ageing compared to the astronaut.
Scientists at the University of Surrey are building a gravity map of Britain for a special BBC 4 programme on gravity.
It will show the different rates at which times flows across the country.
Join in the nationwide project by submitting your results from the app.
App features:* Records how much time you have gained as a result of general and special relativity.* Displays the time gained per day.* Upload your results to build a map of time dilation in the UK.
The app uses your current location to calculate how your rate of ageing varies.
This takes into account both your location and speed.
The app records your location when it is open, and in the background to get a more accurate understanding of your own personal clock.
We have worked hard to make this background collection of locations have as little impact on the battery life of your device as possible, while also providing you with the option to turn background updates off.
Continued use of GPS running in the background can dramatically decrease battery life.
We are committed to protecting the privacy of all our users.
If you decide to upload your data to contribute to the nationwide demonstration, any location information used to calculate time dilation is anonymised, which ensures that your actual location can never be determined.
The locations give us just a broad region in which the data was calculated in order to draw the map.
You will need to confirm your submission via an email from us before we include it in the map.
