Mobile apps & PWAs, without the double build.

One backend, every screen: installable web apps and React Native, chosen for your case, not our invoice.

IN ONE ANSWER

Dev4ager builds mobile apps with React Native and installable PWAs, sharing one backend with your web product, including push notifications, offline support, and store submission. We'll tell you honestly whether you need a store app at all.

What we build

The expensive mistake in mobile is building it twice: separate iOS, Android, and web teams drifting apart. Our architecture is one backend and shared logic with the right surface per platform: React Native where store presence matters, PWA where reach and speed matter.

  • React Native apps for iOS and Android from one codebase
  • Progressive web apps: installable, offline-ready, no store gatekeepers
  • Push notifications, deep links, and native integrations (camera, location, biometrics)
  • One shared backend (Supabase/Postgres) with your web app
  • App Store and Play Store submission, screenshots, and review wrangling
  • Crash reporting and update pipelines (OTA where possible)

How we build it

  1. Scope. First decision: PWA or store app, decided on evidence, not fashion. Then a fixed quote.
  2. Design. Mobile patterns natively: thumb zones, gestures, empty states.
  3. Build + review. AI-assisted build, senior review, real-device testing across sizes.
  4. Ship + iterate. Store submission or install banner, then updates on a real cadence.

A great fit if…

  • Your web product's users keep asking "is there an app?"
  • Your service business needs booking/loyalty in customers' pockets.
  • You have a native app quote that made you sit down; PWA might halve it.

Mobile & PWA FAQs

Native, React Native, or PWA: which do I need?

PWA if your users live in the browser and you want install-without-the-store at web cost. React Native when you need store presence, push on iOS, and deeper device access with one codebase. Fully native only for demanding hardware use; most products never need it.

Do you handle App Store and Play Store submission?

Yes: listings, screenshots, review requirements, and the back-and-forth with Apple and Google until it's approved. We've absorbed the rejection cycles so you don't have to.

Can the mobile app share a backend with our web app?

That's our default architecture: one Supabase/Postgres backend and one API serving web and mobile. One source of truth, one place to fix bugs, features ship to both surfaces together.

How much more does mobile cost than web?

A PWA adds little on top of a web build. React Native typically adds 30 to 60% versus web-only, driven by store requirements, device testing, and push infrastructure. Often the right move is web first, mobile when demand proves it; numbers in the MVP cost guide.
