Defibrillator Cabinet Monitor

I travel the country regularly and wanted an App that pointed you in the direction of a working well maintained defibrillator, this App had all the signs of being what I was looking for, it asked me for the area that I was interested in and I entered Northern Ireland, no defibrillators in the entire province ARE YOU SERIOUS. Then it just becomes another useless App because it will not let you adjust the location and you are effectively locked out. Ho this this idea that you run half a mile to the nearest defibrillator box only to be told to dial 999 and explain to the operator why you need!

Requires Facebook login, totally unnecessary for an app like this. No functionality unless you do provide, or indeed have, a Facebook account
