I would give negative stars for this app and company. After installing I have been bombarded day and night from random phone numbers from all over the world. sometimes ten times per day. I have answered and told them to stop calling. I'm still getng calls. Last night at8:40 pm I got a solitation from this company. I will be taking action and sending my phone records and experience to the better business bureau and a civil complaint to RCMP for harrassment.
