We have developed apps for Android and Blackberry Phones specifically designed to provide protection against stalking and nuisance or abusive calling . The apps will also prevents text or sms messaging giving the phone owner (victim) the ability to block them . Its easy to use , very inexpensive and as we are a social enterprise we are only seeking to recover our costs . Any profits generated we donate to charities involved in giving advice and support to victims . It is also by default an excellent device that prevents mobile cyber bulling and can be used to prevent work place bullying. We have not developed an app for IPhones as Apple will not give access to its operating platform to prevent incoming calls.It is a major security flaw with these phones. We plan to develop with windows platform but as yet handset sales are extreamly small.
