SAME QUESTIONS
BIGGER POSSIBILITIES
01
Should our California startup build a native app or choose Flutter/React Native?
It depends on your product scope and target timeline. For high-compute apps requiring extensive hardware sensor access, advanced AR, or heavy on-device ML, native Swift (iOS) and Kotlin (Android) offer maximum performance. For B2B SaaS portals, marketplaces, and MVPs looking to validate product-market fit quickly, Flutter and React Native allow you to launch on both platforms with a single codebase, reducing time-to-market and budget by up to 40%.
02
Who owns the mobile app source code, intellectual property, and developer accounts?
You maintain 100% unconditional ownership. Pragathi IT Ads builds directly inside your designated GitHub/GitLab repositories. Furthermore, we deploy the final builds using your own Apple Developer and Google Play Console accounts, ensuring your organization retains complete control over user data, subscriber revenue, and software IP.
03
How does Pragathi IT Ads ensure mobile apps comply with California's CCPA/CPRA laws?
We architect privacy-by-design into every mobile build. This includes granular user consent management screens, opt-out mechanisms for data tracking, end-to-end encryption for stored user tokens (Keychain and Keystore), secure biometric authentication (Face ID/Touch ID), and strict adherence to Apple's App Tracking Transparency (ATT) guidelines.
04
What is the typical development timeline to build and launch a mobile app in California?
A feature-rich mobile MVP typically takes 10 to 14 weeks, structured in bi-weekly agile sprints. This encompasses 2 weeks of UX wireframing and clickable Figma prototypes, 6 to 8 weeks of full-stack frontend and backend development with TestFlight staging builds, and 2 to 4 weeks of automated QA testing, security audits, and App Store approval navigation.
05
How do you handle App Store and Google Play rejection risks?
We maintain a 99.4% first-pass store approval rate by strictly adhering to Apple's App Store Review Guidelines and Google Play Developer Policies. We conduct pre-submission audits covering metadata accuracy, content moderation rules, payment guideline compliance, and privacy disclosures before submitting the binary for review.
