Highster Mobile is a low quality, partially functional software with almost no support and no real refund policy. Basic features of Highster Mobile, like SMS messages and GPS locations capturing do work. The more advanced features, like capturing emails and IM chats don’t work as advertised. If you’re lucky and Highster Mobile is compatible with your phone, you will be able to use some basic capabilities. With less luck, you will not receive any help from their support, and your refund requests will be ignored.
