CLEAR ANSWERS

FREQUENTLY ASKED QUESTIONS

How long does it take to build a custom mobile app? +
A focused MVP sprint typically takes 4–6 weeks. A comprehensive dual-platform mobile app (iOS + Android) with custom backend API integrations runs between 8 and 14 weeks. During our discovery call, we outline a firm timeline with milestone deliverables.
Who owns the source code and design assets after launch? +
You do—100%. Upon completion of the project, all Git repositories, Swift/Kotlin source code, Figma design files, backend scripts, and App Store developer accounts are transferred completely to your company. No licensing fees or lock-in.
Do you work with non-technical founders? +
Absolutely. Over half of our clients come to us with a product vision rather than a technical specification. We guide you through user journey mapping, design prototypes, and technology selection in plain English.
Do you sign Non-Disclosure Agreements (NDAs)? +
Yes. We sign a mutual NDA before our initial discovery consultation so you can discuss your product idea with complete confidence.
Native (Swift/Kotlin) vs Cross-Platform (React Native/Flutter)—which should we choose? +
Native is best for apps requiring deep hardware integration (Bluetooth, Metal graphics, high-frequency background GPS, biometric cryptography) or maximum 120fps motion performance. React Native or Flutter is ideal for SaaS, e-commerce, and content platforms looking to launch on both iOS and Android simultaneously while saving ~40% on build costs.
How do you handle mobile app security and compliance? +
We implement hardware-level security, utilizing Apple’s Secure Enclave and Android Keystore for cryptographic keys, local database encryption via SQLCipher (AES-256), TLS 1.3 certificate pinning in transit, and biometric authentication.
What backend technology do you recommend for mobile apps? +
We build performant backends using Node.js (TypeScript), Go, Python, or Laravel, paired with PostgreSQL, Redis caching, and AWS/GCP cloud infrastructure. For rapid MVPs, we also utilize Supabase or Firebase.
How much does custom mobile app development cost? +
Our MVP Sprints start from $18,000 for a focused, single-platform or cross-platform build. Full dual-platform builds with backend infrastructure range from $45,000 to $90,000+ depending on scope. We provide fixed-scope quotes after discovery.
Do you charge hourly or fixed price per milestone? +
We operate primarily on fixed-scope, milestone-based quotes. You will know the exact cost and delivery timeline before any contract is signed.
What support do you provide after the app launches? +
We offer ongoing Care Plans (starting from $2,000/mo) covering 24/7 Sentry crash monitoring, monthly OS compatibility updates (for new iOS and Android releases), security patching, and continuous feature iterations.
What happens when Apple or Google updates their operating system? +
Under our Care Plan, we audit and compile your app against developer betas (iOS 18, Android 15) months before public release, ensuring your app operates flawlessly on day one of the OS launch.
