iPhone shows the app icon with the text ‘loading’ endlessly. This error seems to occur on some devices. The error comes from Apple (iOS) and has nothing to do with PeakFinder.
Most of the people could solve this problem by reinstalling PeakFinder with iTunes and the USB cable. Try the following (see Screenshot):
- Connect your device to iTunes by the USB cable
- Select the device (iPhone) under device in the tree on the left side
- Select the tab ‘Apps’ on the main screen
- Deselect the PeakFinder App
- Press Synchronize (this uninstalls the App)
- Select PeakFinder App again
- Press Synchronize (this reinstalls the App)

If this still does not work, contact the Apple support, please.

Try to clear the Market cache. This usually solves installation problem on Android:
- Menu Button
- Settings
- Applications
- Manage Applications
- Filter All
- Select Market app, and then tap ‘Clear data’ and ‘Clear cache’
- Select Download manager and tap ‘Clear data’ and ‘Clear cache’

If this is not working checkout the Android support page please.

The compass must be activated. Touch the compass button top right. The compass will be deactivated when you select a new viewpoint.

To obtain the correct direction PeakFinder uses the compass sensor of your device. This sensor is not very precise and sensitive to magnetic fields. To get a better result move from any disturbance source. Additionally you can calibrate the compass by rotating the device with activated compass around every axis (see this youtube movie). Sounds like Voodoo but it works.

Make sure that under ‘Settings->Location-Services->System Services (scroll down)’ the Setting ‘Compass Calibration’ is On.

‚Augmented Reality’ Apps use the camera, the acceleration- and magnetic sensor of the smartphone. These Apps overlay additional information to the camera picture. E.g. you could show the names of the peaks when you head your device in the direction of a mountain range. The problem is that the magnetic sensor has usually a bad accuracy (+/- 20° is quite common) and the camera has a very wide angle (70°). These factors give unsatisfying results. For this reason this function won’t be added to PeakFinder in the next time.
