    “The freelancer's english is very bad and cannot communicate well. His knowledge and skills is also very limited and thus had issues completing the job. However when the Android version of the app was incomplete he asked for payment and said he would not complete the job unless I did. He gave all sorts of excuse and wasted my time. He could have used this time and complete the job. After many days, he threatened to sell my source code(the app is a very special app and made use of special numerology calculations (you can see a version made by OTHER freelancer: [login to view URL])) I told him we had a signed NDA but he said he would still do so. After ignoring him and contacting freelancer support, he said he had sold the app. After a few days he contacted me again asking to continue and complete the iOS version of the app. Obviously I did not send him the iOS source code in case he would sell it, however he said he was just joking and did not sell the source code. However I think he had sold my source code as I have seen similar version of my app which are using very similar calculations. I would not advice working with this freelancer as he will cheat your money. There is no way anybody, not even [login to view URL], can check what he is doing in his home. Even if you are able to find a similar app on the app stores, it is very difficult to get evidence and trace the freelancer who had sold your app idea and source code to take actions against him and take down the app.”
