We use React Native with Expo, which allows a single codebase to produce both apps. This reduces cost and build time and it means every feature is available on both platforms together. It also makes the project easier to maintain, because a future developer works with one set of code rather than two.
We start with a discovery and scoping phase, then work in milestones with agreed deliverables. You see progress at each milestone and can approve the next stage before it begins. This avoids the common problem of estimates doubling halfway through the project, because the scope is defined and reviewed in stages.
Yes. Every package includes a backend API and an admin panel, so your team can manage users, content and orders without developer help. The backend is built with Node.js and PostgreSQL and it is documented so that it can be maintained by others in future.
Common features include sign in, user profiles, push notifications, payments, maps, location features and over the air updates. The Starter package covers core features for a first version, while Growth and Premium add payments, maps and more advanced functions. If you need something unusual, we assess it during discovery and include it in the quote.
Yes. We prepare the store listings, assets and builds and we handle submission and review feedback for both stores. You remain the owner of the developer accounts, so the app stays under your control. After launch, a 30 day warranty covers defects in the delivered work and the Premium package offers an extended warranty.
Starter is $5000 in 4 to 8 weeks, Growth is $17500 in 10 to 16 weeks, and Premium is $60000 in more than 20 weeks. The final price depends on the number of features and integrations, and custom projects are quoted after discovery. App Care at $299 per month covers updates, monitoring and support after launch.
