One Peak

Mobile · Expo

One Peak for Expo development.

Expo is how we ship most React Native apps in 2026: managed builds, over-the-air updates, and store submission tooling that removes weeks of native configuration. For startup MVPs, it's the shortest credible path to both app stores.

Why Expo for startup apps

Expo turns the slowest parts of mobile delivery — signing, builds, releases — into configuration.

  • EAS Build: cloud builds for iOS and Android without a Mac fleet
  • OTA updates: ship fixes without waiting on store review
  • Config plugins cover most native needs without ejecting
  • One workflow from prototype to production

When Expo is the wrong call

Deep custom native modules, specialized hardware integrations, or unusual background processing can outgrow the managed workflow — we flag that in scoping, not after.

How we use it

Every Expo app we ship includes a release pipeline you own: EAS configured under your accounts, preview builds for stakeholders, and OTA channels for staged rollouts.

Frequently asked questions

Is Expo production-ready or just for prototypes?

Production-ready — companies ship serious apps on Expo. The old 'eject to get real' advice is years out of date thanks to config plugins and EAS.

Can Expo apps use custom native code?

Yes — config plugins and development builds support custom native modules while keeping the managed workflow benefits.

How do over-the-air updates work with app store rules?

OTA updates ship JavaScript-level changes within store policies; native changes still go through review. We set up both paths.

Does Expo lock us in?

No — an Expo app is a React Native app. You can move to bare workflow anytime; the code and accounts are yours.

How fast can an Expo MVP ship?

TestFlight in 4–6 weeks for a two-feature app, store release in 6–8 — the same baseline as our other mobile work, minus native build friction.
