When you break down in the middle of nowhere the AA app is useless. It also has trouble logging you in. If you're on a busy road you're not looking up like you would be on the phone to observe cars whizzing past your broken down car. So the app is a bad idea. It actually puts you at greater risk of focusing too much on your phone than being aware of your surroundings. If you use the phone you get a 30 seconds automated message about safety. However the message is a basic one and anyone with common sense will have automatically done it. When you get through to an advisor they repeat the same message. In my opinion the phone call is the better and safest option as you're looking up at the traffic and you're aware of your surrounding. With the app you're looking down and distracted. Plus it needs regular updates running and it will log you out.....
