Android Application for Intervention Services

I decided to write this diploma thesis because I am a volunteer firefighter in my local fire department. Each year we conduct preventive check-ups of hydrants and water tanks in our region. We write down our observations on a piece of paper. Since these documents are later stored in an archive, they are not very helpful during an intervention. However each firefighter owns a mobile phone that could potentially be used to access the information on the nearest hydrants and their condition, for any location within the municipality. For phones with NFC, I have decided to make a timer as part of the applicationl. The timer can be set when firefighters enter a burning building, and it will give off a warning after a certain period of time has passed
