【實用旅遊app】IpSmartAltimeter|最夯免費app-綠色工廠好玩App

IpSmartAltimeter is SmartWatch extension to display pressure sensor based altitude on your SmartWatch. To be able to use IpSmartAltimeter you need to have a phone with a pressure sensor. Phones with pressure sensors include Sony Active, Sony GO, Galaxy Nexus, Galaxy Note or Galaxy S III. You also clearly need a SmartWatch.

There are options to lock the display bright or dim or leave it in automatic mode. If you lock it your battery will drain fairly quickly. Just touch the icons.

Swipe up or down to switch from the altimeter screen to a time screen.

On start-up if the pressure has not been calibrated within 2 hours then GSP based calibration is attempted.

The GPS is started, if a good location if obtained within 2 minutes this location is used to check the altitude cache.

If there is an entry in the altitude cache it is used to calibrate the altimeter.

If no cached entry is used then an online lookup is attempted for the location.

The resulting altitude and location are added to the cache and used to calibrate the altitude.

You can swipe left and right for the manual calibration screen and the settings screen.

Press to toggle filtering on and off and units from as meters or feet in the settings screen.

In the manual calibration screen swipe up to delete the last digit, swipe down for zero.

If the value is red then there is not currently a good location and the calibration will not be added to the cache.

If the value is green the location and manual altitude will be added to the cache.

Swipe right or left to set the altitude and exit the calibration screen.

I currently consider this to be beta.

Any problems please feel free to email support@iforpowell.com

I request the Internet permission for the crash reporting system I use and the analytics system as well as for doing the online altitude lookup. The analytics uses Flurry and is anonymous, I am just interested in how the app is being used in order to make improvements. There are options in the settings screen to switch off the crash reporting and the analytics if you want to.

I request the gps permission to look up the location in order to do automatic calibration. I stop looking up after two minutes if a good fix is not obtained.

I request access to external storage to save the calibration cache data.

I request the network state to help deciding if an online altitude lookup is possible.
