We make apps faster, smaller, and, above all, more secure.


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


Mobile applications are becoming big. Shiny features and bulky libraries can be a challenge. Our software reduces app sizes, by removing unnecessary code and resources. It typically reduces apps by 20 to 90%, resulting in smaller downloads, less memory requirements, faster startup times - resulting in a better user experience.


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.

"We have undergone a security evaluation by an independent lab and the obfuscation of the code was deemed very good. So congratulations!"

Gartner says:

"More than 75 Percent of Mobile Applications Will Fail Basic Security Tests through 2015"

Android is the prime mobile target for cyber criminals:

87% of mobile devices are Android (Forbes), but Android has some disadvantages. Android apps are easy to reverse-engineer. There are a lot of hacking tools available that are free and easy to use and let anyone reverse-engineer or even 'trojanize' an Android app. Android is responsible for 92% of all known mobile malware.

Possible vulnerabilities for unprotected apps:

Insertion of malware, (key logging, password snooping, connection tampering), theft of data & intellectual property, swapping advertisements, changing brands, bypassing authentication logic, piracy, and last but not least loss of credibility.


Google recommends to run an obfuscation tool like Proguard at a minimum. In addition they recommend to:

  • Inline methods into other methods.
  • Construct strings on the fly instead...
