My app idea was stolen. How to get around it?

Do I use disclaimers such as these?<br><br>This is not a formal patent application. In the United States it is illegal to use a patent pending number for fraudulent purposes. Providing this information does not remove legal liability if you produce and make for sale a patented idea.<br>An idea or suggestion is not a patent. You may still be infringing if you use this idea to design an invention that is currently covered by an active patent.<br>A patent pending number is not a patent. It may be approved or denied and may not protect you from legal liability.<br>This is not a substitute for a formal patent and should not be used as such.<br><br>usablepatents.com<br><br>Or are there other options out?<br><br>Thanks
