$20K–$120K typical projects
Direct answer
Expo app development typically costs $20K–$120K — the low end for a focused MVP shipped to both app stores, the high end for a full-featured product with native integrations, offline support, and a mature release pipeline. I build Expo apps end to end myself, with 20+ App Store launches behind me, 7+ years of production delivery, and apps used by millions of users. Engagements run on fixed milestones with a build on your phone within the first two weeks via TestFlight and internal Android tracks, so progress is something you tap, not something you read about in a status report.
Expo has quietly become the default way serious teams ship React Native — one codebase, both stores, over-the-air fixes, and a build pipeline that does not require a Mac lab. The catch is that Expo's convenience punishes bad architecture at scale just like anything else. Delivery succeeds when someone who knows where Expo's boundaries are designs the app so you never hit them by surprise.
You need an MVP or v2 shipped on budget with someone who makes architecture decisions and owns delivery end-to-end.
You need a senior IC to augment the team, rescue a codebase, or lead mobile + AI integration without months of hiring.
You need a reliable senior subcontractor for client projects — clear communication, store-ready quality, white-label friendly.

A founder has designs and a validated idea, and needs a real app on iOS and Android without funding two native teams. I build the product on Expo — navigation, auth, payments, push notifications — with EAS handling builds and store submission. Both stores in weeks, one codebase to maintain, and OTA updates for the fast iteration that follows launch.
A team's bare React Native app has become a build-system tar pit — days lost to Xcode and Gradle breakage every upgrade cycle. I migrate them onto Expo's managed workflow with config plugins replacing their native tweaks, and EAS replacing their fragile CI. Upgrades drop from a week of pain to a routine chore, and the team ships features again.
A company's Expo app ships rarely because releases are manual and terrifying. I build out their EAS pipeline — internal distribution channels, staged rollouts, over-the-air updates for JS-level fixes, and store submission automation — then document the runbook. Shipping goes from a monthly event to a low-drama weekly habit, and critical fixes reach users in hours.
Expo fits the overwhelming majority of apps being built today: products whose value is screens, data, camera, maps, payments, notifications, and business logic. For those, it removes the two most expensive parts of React Native — native build maintenance and release logistics — and current Expo supports almost any native module through config plugins and development builds, so the old "Expo is too limited" objection is mostly folklore now.
Where I steer clients away: apps whose core is heavy custom native work — real-time audio processing, advanced AR, specialized hardware SDKs with no maintained module — or teams with deep native expertise already invested in custom build tooling. Those are the honest exceptions. If a developer tells you Expo cannot handle your standard product app, they are either years out of date or selling you a more expensive project than you need.
Week one produces a running skeleton: project setup, navigation structure, design tokens, EAS configured, and a build installed on your actual phone — because a stakeholder holding the app changes every conversation that follows. Weeks two through six ship vertical slices of real features, each landing in a TestFlight and internal Android build you can tap that same week: auth, the core loop, payments, push, whatever your product's spine is.
The final stretch is store readiness, which trips up teams who have never launched: privacy manifests and data-safety forms, screenshot sets, review-guideline landmines, staged rollout plans. With 20+ App Store launches behind me, this phase is a checklist rather than an adventure. Post-launch, OTA updates handle JS-level fixes in hours while store binaries follow their slower cadence — the two-speed release rhythm that makes Expo worth it.
Feature depth sets the floor. A clean MVP — auth, a core workflow, payments, push — lands in the $20K–$45K band. From there, the multipliers are the features buyers underestimate: offline support with sync and conflict handling can add more than the rest of the app combined; real-time collaboration, chat, or live tracking adds server coordination; heavy media handling — video capture, editing, upload pipelines — adds another layer.
Native surface matters too: every capability needing a custom config plugin or native module adds work, though far less than it would in a bare workflow. Design maturity moves timelines meaningfully — finished Figma files versus design-as-we-go is often a thirty percent swing. And launching under a deadline pegged to a marketing moment compresses everything and prices accordingly. What does not drive cost anymore: targeting both platforms, which is precisely the economics Expo exists to deliver.
Ask for apps they have shipped that you can install right now — store presence is the credential that cannot be faked, and someone with many launches will hand you links without hesitation. Ask how they decide between OTA updates and store releases; the answer reveals whether they understand both the technical boundary and the store-policy line you must not cross, which is exactly the knowledge that keeps your app out of review trouble.
Ask what they would do when a needed capability has no Expo module — the senior answer involves config plugins and writing a native module inside the Expo framework, not "eject." Recommending ejection at the first obstacle is the biggest tell of an out-of-date developer, and it saddles you with permanent build maintenance to solve a temporary problem. Finally, ask about their upgrade story: Expo moves fast, and apps that skip upgrade discipline pay compounding interest.
The most common is treating store launch as an afterthought — budgeting to the moment the app works, not the moment it is approved. Store review, privacy declarations, and rejection cycles reliably consume two to four unplanned weeks for teams who have not done it before; make your vendor own approval, not just code-complete. The second is skipping the release pipeline: an app without EAS channels, staged rollouts, and OTA discipline ships version one and then freezes, because every subsequent release is terrifying.
Third is the abstraction panic — some stakeholder hears "cross-platform" and demands native rewrites for performance problems nobody has measured. Modern Expo apps are indistinguishable from native for the vast majority of product categories; performance issues that do appear are almost always fixable application-level mistakes. Insist any performance claim, pro- or anti-Expo, arrives with a profile attached.
If your product is unvalidated, do not commission any app yet — a responsive web version or even a well-crafted waitlist tests the demand thesis for a tenth of the budget, and app stores punish half-committed products with visible abandonment. Build the app when mobile is genuinely the product: when you need push, camera, offline, home-screen presence, or the retention loop only an installed app provides.
Skip Expo specifically — and accept the higher cost of native or bare workflows — only when your core feature is deep native territory: professional audio, advanced AR, hardware SDK integration with no maintained module. And if you already have a healthy native app with a native team, migrating to Expo for its own sake is rarely worth it; the migration pays off when build maintenance is actively bleeding the team, not before. I will tell you which case you are in during the first conversation.
You approve milestones and a price before any build starts — no open-ended hourly surprises.
You see running software each week, not status reports, so you can course-correct early.
The person who scopes the work is the person who builds it — no junior layers, no agency markup.

Typically $20K–$120K for both platforms. A focused MVP with auth, a core workflow, payments, and push runs $20K–$45K. Offline sync, real-time features, heavy media handling, or custom native modules push builds into the $60K–$120K band. The both-stores requirement no longer multiplies cost — that is exactly the economics Expo delivers — but underestimated features like offline support absolutely do.
An MVP takes eight to twelve weeks to approved store listings: one week to a build on your phone, five to seven of weekly feature increments through TestFlight, then two to three for store readiness and review cycles. First-time launchers should budget the review phase seriously — privacy forms and guideline rejections consume unplanned weeks when nobody on the project has shipped before.
Default to Expo. Modern Expo handles nearly any native requirement through config plugins and development builds, while removing build maintenance and release logistics — the most expensive recurring costs of bare React Native. Choose bare only when your core feature demands deep custom native work with no maintained module, or your team already runs specialized native tooling. Developers recommending bare "for flexibility" without a named concrete need are usually just out of date.
