Cross-Platform Mobile App Build

I need a brand-new mobile application built for both iOS and Android, delivered as a single, cohesive code-base that feels completely native on each platform. All core features and user flows are already mapped out on my side; I will pass along wireframes, a detailed functional specification, and brand assets as soon as we kick off.

The job covers the full life-cycle: refining the technical architecture, crafting a polished UI, coding the front-end and any required back-end services, thorough QA on real devices, and finally shepherding the builds through App Store and Google Play submission. A modern cross-platform stack such as Flutter, React Native, or another comparable solution is perfectly acceptable—feel free to advocate for the approach you believe will give the smoothest performance and easiest long-term maintenance.

Deliverables I expect:
• Interactive design prototypes for approval
• Complete, well-commented source code and project files
• Fully functional iOS (.ipa) and Android (.aab) release candidates
• Test reports confirming smooth operation on current OS versions and a representative device set
• Store-ready listings and successful submissions

Acceptance criteria: each build must match the supplied specification pixel-perfectly, achieve 100 % pass on all agreed tests, and comply with Apple and Google review guidelines without unexpected rejections.

Timelines are flexible enough to allow for considered craftsmanship yet focused on achieving a prompt launch. Ongoing collaboration for updates is definitely on the table once the initial release proves stable.
