“The design system they built is now the source of truth across four products. That's the long-tail value most agencies miss.”
Questions, answered.
Hybrid or Native — which should we pick?
Hybrid (React Native / Flutter) ships one codebase to both stores and is faster and cheaper. Native (Swift / Kotlin) gives you absolute polish, the latest OS features, and best-in-class performance — pick it when the app is core to your product.
Do we own the code?
Yes — 100%. Source, design files, and infrastructure are transferred to you on request. No lock-in.
Do you submit to the App Store and Play Store for us?
Yes. Submission, store listing copy, screenshots, and review-response are part of every plan.
What about Apple Developer and Google Play accounts?
Apple Developer ($99/yr) and Google Play ($25 one-time) accounts stay in your name — we set them up and manage them with delegated access.
Can we extend or cancel after the minimum term?
Yes. After the 3 or 6-month minimum, the retainer rolls month-to-month with 30 days' notice. Maintenance can continue on the $799/mo add-on.
