   The de facto standard for mobile app analysis — open-source, covers both iOS and Android, combines static analysis (source and compiled IPA/APK) with a manifest/entitlement/secret/hardcoded-key scan and OWASP MASVS/MASTG-mapped output; huge community, CI-friendly REST API, and it handles the reality that most engagements start from a binary, not source. Best default for the typical mobile pentester or AppSec engineer.

   Claude The de facto standard for mobile app analysis — open-source, covers both iOS and Android, combines static analysis (source and compiled IPA/APK) with a manifest/entitlement/secret/hardcoded-key scan and OWASP MASVS/MASTG-mapped output; huge community, CI-friendly REST API, and it handles the reality that most engagements start from a binary, not source. Best default for the typical mobile pentester or AppSec engineer.

   Gemini The undisputed gold-standard open-source tool, offering completely free, self-hosted, and offline static analysis across Android (Java/Kotlin, APK) and iOS (Swift/Objective-C, IPA) codebases, with comprehensive baseline manifest, permission, and MASVS mapping without sharing proprietary code with external vendors.

   Where it falls short

   per Claude Its static engine is rule/pattern-based with meaningful false positives and shallow dataflow; it is a triage-and-coverage tool, not a deep taint-tracking SAST, and needs a skilled reviewer to separate signal from noise.

   per Gemini Relies heavily on regex and pattern matching rather than deep interprocedural data-flow analysis, resulting in higher false-positive rates and an inability to trace complex multi-step data leaks.

   The enterprise standard for continuous automated mobile pipeline security (near-tie with Oversecured on mobile vulnerability coverage and MASVS compliance), delivering turnkey CI/CD integration, rich developer remediation guidance, and deep static inspection of app code alongside third-party SDK dependencies.

   Gemini The enterprise standard for continuous automated mobile pipeline security (near-tie with Oversecured on mobile vulnerability coverage and MASVS compliance), delivering turnkey CI/CD integration, rich developer remediation guidance, and deep static inspection of app code alongside third-party SDK dependencies.

   Claude The strongest commercial mobile-dedicated offering — combines automated SAST with DAST/IAST on real devices, MASVS/MASTG certification alignment, and enterprise reporting/governance; purpose-built for mobile by the team behind much of the MASTG lineage, making it the practical choice for regulated orgs needing auditable, low-false-positive results at scale.

   Where it falls short

   per Claude Expensive and enterprise-oriented; overkill for individual practitioners or small teams, and its value is in the full dynamic+static platform, not standalone SAST.

   per Gemini High enterprise price point and heavier scan overhead make it poorly suited for individual developers or teams needing instantaneous, lightweight pre-commit pull-request feedback on raw source lines.

   Claude #2Gemini #4

   Best-in-class custom-rule SAST for source code, with strong first-party and community rulesets for Kotlin/Java (Android) and Swift/Objective-C; fast, CI-native, low-friction to write org-specific rules, and excellent for shift-left developer workflows where you own the source. Near-tie with MobSF — it wins when you have the codebase, MobSF wins when you have the binary.

Near-tie with MobSF — it wins when you have the codebase, MobSF wins when you have the binary.

   Gemini Outstanding scan speed and developer ergonomics for shift-left mobile SAST, featuring fast native parsing for Kotlin, Java, and Swift in PR workflows alongside an accessible rule syntax that lets teams easily codify internal security standards and secure coding patterns.

   Where it falls short

   per Claude Source-only and largely intra-file/limited-interprocedural in practice; it doesn't analyze compiled IPA/APK, has weaker Swift/ObjC depth than JVM languages, and won't catch config/entitlement/binary-hardening issues.

   per Gemini Lacks built-in mobile domain intelligence out of the box; without manually maintained or premium mobile-specific rulesets, it cannot natively analyze mobile platform primitives like Android IPC/Binder mechanisms or iOS runtime behaviors.

   Claude —Gemini #1

   Exceptional technical depth in mobile-specific static taint tracking (intent redirection, pending intents, arbitrary file overwrites, exported component flaws, iOS keychain and deep-link vulnerabilities) with an industry-leading low false-positive rate and automated proof-of-concept generation; ranks first assuming deep discovery of mobile architectural and data-flow flaws matters more than broad generic linting.

   Where it falls short

   per Gemini Expensive commercial SaaS with a closed-source engine and limited custom rule-authoring capabilities, making it unsuitable for teams requiring air-gapped on-premises deployments or budget-constrained projects.

   Deep interprocedural taint analysis with genuine mobile coverage (Java/Kotlin, Swift/Objective-C) inside a mature enterprise SAST platform; strong dataflow tracing across the codebase, SDLC integrations, and remediation guidance — the pick when mobile is one part of a broader source-code AppSec program.

   Where it falls short

   per Claude Heavyweight, costly, slow scans, and tuning-intensive; mobile is not its specialty, so it misses mobile-specific binary/runtime concerns and is poor for binary-only assessments.

   Gemini Powerful semantic code analysis engine with deep cross-function taint tracking and queryable ASTs supporting Kotlin, Java, and Swift, fully integrated into GitHub workflows and available at zero cost for public repositories.

   Where it falls short

   per Gemini Heavy compute overhead and strict build extraction requirements (compilation must succeed inside CodeQL), coupled with a steep learning curve for writing custom QL queries, making it a poor fit for rapid pipeline feedback or binary-only analysis.

   Automated mobile-focused scanner (open-source community edition plus a commercial platform) that ingests APK/IPA directly, blends static checks with dynamic and dependency/SBOM analysis, maps to MASVS, and integrates into CI — a pragmatic, mobile-native complement to MobSF with better orchestration and vuln correlation.

   Where it falls short

   per Claude Smaller ecosystem and less battle-tested than the leaders; full capability sits behind the paid store scanner, and standalone static depth is modest.
