KEEP YOUR MOBILE APPS FAST, SECURE & ALWAYS COMPLIANT
Proactive maintenance, performance tuning, OS compatibility upgrades, and legacy code refactoring to protect your app's 5-star rating.
Engineered for Compound Retention & High ROI
Both Apple and Google release major OS updates and deprecate SDKs annually. Without active maintenance, apps suffer from battery drain, security vulnerabilities, store policy warnings, and user churn. AppGuru provides continuous mobile app maintenance, performance audits, security patching, and full codebase modernizations (e.g., migrating Objective-C to Swift, or Java to Kotlin Compose).
AppGuru pairs studio-grade visual aesthetics with battle-tested software engineering. Every build is accompanied by strict automated testing, zero memory leaks, and transparent milestone governance.
