Hints and tips

Offline use

TPE on iOS supports offline use. To get the most out of the app when offline, you should follow a few guidelines:

  • Save the locations you will need to use. This ensures that TPE has stored the timezone and elevation above sea level (these are required to provide the most accurate data).
  • Select one of the offline map options (OpenCycleMap Topographic, MapQuest OpenStreetMap – these options can be selected via the map type controls on the map, but you will need to have Google Maps set as the selected map technology in the app’s Settings screen)
  • Pan and zoom the map to cover the areas you will need to view when offline. Doing this will save the map tiles to your device for use when offline.

If you are offline and didn’t view the required maps areas in advance, it’s possible the map image tiles will still be in your device’s local cache, but you cannot rely on it. Use one of the offline map types, and view the map tiles you need in advance, for reliable map access when offline.

TPE will look up the local time zone for wherever you are looking on the planet, so you don’t have to second guess. However, it needs an internet connection to do that. If there isn’t one available, you will be prompted to specify a time zone manually.

Finally, TPE also looks up elevation above sea level for both primary (red) and secondary (grey) map marker locations. Elevation above sea level affects the actual time of rise/set and apparent position of the sun/moon in the sky, due to atmospheric refraction. If there’s no internet connection, TPE will assume that the location is at sea level (which is what very many sunrise/set calculators do all the time), and the data will be very slightly less accurate as a result.

For the secondary map marker, knowing the elevation above sea level is essential – this is how you determine the angle of elevation to a nearby mountain-top, for example. With no internet connection, the geodetics information cannot be determined.

Error on searching for place name

If you receive an error when searching for a place name, it is possible that the Google web service supporting this function is temporarily unavailable.

In other cases, we have seen that some users have to restart their device in order for the search function to become available again.

If you have trouble searching for locations, please try waiting an hour or two, and/or restarting your device. If search is still not working, please e-mail us at the support address above

Unable to find Google Play Services on Android Market

TPE for Android 1.1 and above requires Google Play Services to be installed. Some older Android devices may still have the Android Market app installed, instead of the more modern Google Play store app.

A bug in the Google Maps API v2 means that it assumes that you have Google Play Store installed and as a result clicking the “Install” button will either do nothing or crash an app in this case. TPE attempts to detect if you have the old Market app installed and presents a different install message that should direct you to the Android Market to install Google Play Services.

Here is the direct link for Google Play Services:

If you can’t find Google Play Services via the prompts presented in TPE, please click on the appropriate link above, depending on whether you have Google Play or Android Market on your device.

If you are unable to get Google Play Services installed on your phone, please email us for support.

TPE for Desktop Web App

We’ll be adding support information specific to the web app here. In the meantime, if you’re having any problems, please email us at with details.

Known issues

  • Slow performance after switching pages multiple times: the web app may load more slowly after switching between pages multiple times due to increasing memory consumption. In most browsers, this can be resolved by reloading the page manually. Internet Explorer 11 may need to be restarted to resolve this condition.

TPE for Desktop (Legacy Adobe AIR app)

The legacy Adobe AIR app is no longer supported. Google disabled Google Maps for Flash API on 2 Sep 2014 and the old desktop app is no longer functional.
