Need Script to Protect Native Apps from Piracy

We build Android, IOS and Kindle Apps using Seattle Clouds app building software. We need to find a good Obfuscation anti-copy, anti-tampering, anti-piracy, anti-reverse engineering script to protect our apps. Please get in touch if you specialise in this field and create software solutions that can protect native apps as detailed above. When you bid please send us details of EXACTLY how your script will protect our app code. We have a budget of around $50 to $150 for this project. Please PM if interested
