Our software protects apps while making them faster and smaller.


Mobile applications are vulnerable. When you've secured your server, storage and communication, the app remains the weakest link for attackers. Our software hardens apps against on-device and off-device attacks. Keep your software safe from reverse engineering and tampering. Save time and effort with our state-of-the-art protection techniques.


Mobile applications are never fast enough. Nicely abstracted code and external libraries can be at odds with performance goals. Our software optimizes the apps again, improving performance by 20%. Your customers will thank you for providing a better experience.


Mobile applications are becoming large. Shiny features and bulky libraries can be a challenge. Our software reduces the application size by 20 to 90%, resulting in a smaller download time and fast app usage. Your users will enjoy a superior experience.
