I would like to save the altitude in my app and use it to check if the device is at the same altitude in the future. Using GPS will not be applicable because of minimal power usage restrictions in my app.
Would it be possible to do such a thing? I don't care about the altitude value being correct, as long as it is the same (almost same... i can work with ranges) at the same location all the time. Thanks.
