Easy-as-pie Android Decompiler is a free mobile app security tool. DerScanner Mobile Application Security Testing (MAST) is a commercial mobile app security tool by DerSecur. Compare features, ratings, integrations, and community reviews side by side to find the best mobile app security fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Mobile app security teams doing Android threat analysis or code review will move faster with Easy-as-pie Android Decompiler because it regenerates R references during decompilation, eliminating the manual remapping that turns a 30-minute review into three hours. The 688 GitHub stars reflect active use in both defensive security and red team workflows. Skip this if you need a GUI-driven tool with integrated SAST or if your threat model includes obfuscated third-party SDKs, since Easy-as-pie focuses narrowly on decompilation output quality rather than semantic code analysis.
DerScanner Mobile Application Security Testing (MAST)
Security teams shipping Android and iOS apps need DerScanner Mobile Application Security Testing to catch vulnerabilities in binaries already live on app stores, not just pre-deployment code. It scans published applications directly from Google Play and the App Store,a capability most MAST tools skip,and maps findings to both OWASP Mobile Top 10 and MASVS standards, covering the verification frameworks buyers actually audit against. Skip this if your organization needs a single platform handling web APIs, backend services, and mobile apps together; DerScanner is mobile-only and doesn't integrate with your existing SAST pipeline for server-side code.
