Ever wondered how tall a tree is? If that tree were to fall, or be cut down, what would it hit? With Timber tree height estimator you can now easily estimate the height a tree. After you measure the tree Timber will display the height and a red circle on a map to show you an estimated area of where the tree would fall. Timber doesn't only measure the height of trees. It will give you a good estimate of any object you want to measure. To use Timber you set the GPS position of the tree that you want to measure. Then walk away from the tree and use the app to measure the angle to the top of the tree. Timber will then calculate the height of the tree. You can also set, or adjust, the position of the tree and your current location on the map. This comes in useful if you have a poor GPS signal or if you can not get to the tree to set the position.

OnDutyControl - the app for controlling our mobile home platform OnDuty OnDutyCore is a smart and intelligent control for your motorhome / yacht / boat or your isolated solution. With OnDutyCore, all components of your system are combined in one uniform operation. All functions of the system can be conveniently controlled via the permanently installed display by touch operation and also via an application on your tablet or smartphone. The operation can be used on any number of devices and becomes active when you are in the WLAN network of the vehicle. The variant of the permanently installed display can of course also be used without WLAN. The integration of all components in the system not only enables operation via a single interface, but can also produce energy-saving functions for the first time through intelligent dependencies. For example, the energy surplus of a solar system with full batteries can be used to operate the refrigerator and thus conserve the gas supply and extend the self-sufficient time. With OnDutyCore, the provisioning of the system becomes a cinematic game.
