For 95% of businesses, cross-platform frameworks like React Native or Flutter provide identical 60fps performance while cutting development and maintenance costs in half. We recommend purely native Swift/Kotlin only when deeply custom hardware or graphics shaders are required.

Yes. We prepare developer accounts, privacy policies, screenshot assets, beta testing groups, and communicate directly with Apple/Google reviewers to secure approvals.

Yes. We build offline-first architectures that save data locally and synchronize automatically once connection is restored.

We implement biometrics (Face ID / Touch ID / Fingerprint), OAuth social logins, and store auth tokens inside Apple Keychain and Android Keystore.

Yes. We integrate RevenueCat, Apple In-App Purchase, and Google Play Billing with automated server receipt validation.

A polished MVP typically takes 8 to 12 weeks, while complex social, fintech, or hardware-connected apps require 12 to 18 weeks.

Yes. We ensure your app stays compatible with annual iOS and Android OS updates, fix emerging bugs, and deploy continuous feature iterations.
