Mobile product design and development
Cross-platform mobile products planned, designed, built, tested, and prepared for app-store submission.
A mobile product is most useful when repeated use, notifications, offline access, camera or location features, or a focused touch interaction genuinely belongs on the phone.
I use React Native and Expo when a shared iOS and Android foundation fits the product, while still planning for platform-specific permissions, store requirements, device behavior, accessibility, and testing. Depending on the scope, the build can include notifications, offline behavior, secure login, camera access, maps, payments, analytics, and release preparation.
The release plan documents what works without a connection, what data leaves the device, how errors recover, which devices are supported, and what remains controlled by Apple or Google. Store approval is never represented as guaranteed.
These are common capabilities, not a compulsory package. We choose what supports the agreed outcome, then record the deliverables, responsibilities, ownership, and handoff in writing.
Are You SOS and Tap the Safe show two very different mobile systems: a privacy-first support tool and an offline-first puzzle game.

01A privacy-first accountability app for sobriety, mental wellness, and personal safety, with clear check-ins, trusted contacts, and offline support.
02An ad-free number-deduction game with a 100-level campaign, daily challenge, infinite modifier ladder, and opt-in real-player competition.
These are the questions clients usually raise about this kind of work. If your situation is different, ask it directly—there is no sales sequence or account-manager handoff.
Ask a different questionYes. I commonly use React Native with Expo to share the product foundation across iOS and Android. Shared code improves efficiency, but each platform still receives the device testing, permissions, configuration, and release work it requires.
Timing depends on the product states, accounts, offline behavior, integrations, device features, testing matrix, and store requirements. I scope the first complete release before assigning a schedule, then separate later enhancements so the initial build remains understandable and testable.
I can help prepare developer accounts, screenshots, store descriptions, release builds, and submissions for the agreed platforms. Apple and Google control review decisions and may request changes before approval.
