Mobile App Development
Mobile apps that ship to the App Store.
Starting at
From $8,000
Timeline
4–8 weeks
Mobile development is full of landmines: App Store rejections, push notification setup, in-app purchase StoreKit configuration, iOS 17 vs iOS 18 quirks, Android push reliability, App Tracking Transparency, privacy manifests. A first-time submission has a roughly 40% rejection rate.
We build cross-platform apps with React Native (Expo) when you need iOS + Android fast, and native SwiftUI when you need Apple-grade polish or HealthKit-deep integration. Either way, you get a real app in the App Store, not a prototype.
Every mobile project includes the backend API, in-app purchase setup, push notifications, deep links, App Store and Play Store submission, and the privacy paperwork Apple now requires. We handle the review process — including responding to rejections.
What's included
Every project ships with everything below — no surprise add-ons.
iOS, Android, or both
React Native (Expo) for true cross-platform — one codebase, both stores. SwiftUI for native iOS when you need HealthKit, ARKit, or Apple-grade animation.
App Store + Play Store submission
We write the listing copy, take screenshots in the right device frames, fill out the privacy questionnaire, and submit. Including the App Tracking Transparency dance.
In-app purchases & subscriptions
StoreKit 2 (iOS) and Google Play Billing (Android) wired up properly — receipts validated server-side, restore purchases working, free trials handled.
Push notifications
APNs and FCM setup, device token storage, and a way to send notifications (OneSignal, Expo Push, or a custom server).
Camera, location, HealthKit
Whatever device APIs your app needs. Permissions handled gracefully — no "why does this app want my camera" rejection from Apple.
Backend API
Supabase, Firebase, or a custom Node/Python backend. Auth, data, file storage, push triggers — everything the app talks to.
OTA updates
EAS Update (Expo) or a custom OTA path so you can ship JS-only fixes without resubmitting to the App Store.
How it works
Same playbook for every project. Predictable, weekly demos.
Week 1 — Stack decision + scaffolding
We decide React Native vs SwiftUI based on your features. Set up the repo, EAS or Xcode project, signing, bundle IDs. By end of week 1 you have a TestFlight build of a 'Hello World' with your branding.
Week 2–4 — Core features
Your main user flows. Auth, data, payments, the screens that make the product feel like itself. New TestFlight build every Friday.
Week 5–6 — Polish + integrations
Push, deep links, HealthKit/Camera/Location, IAP edge cases, dark mode, accessibility. The 'making it not feel beta' phase.
Week 7–8 — App Store submission
Screenshots, listing, privacy questionnaire, submission. We handle reviewer responses if they push back. Live within 1–2 weeks of submission.

Frequently asked
The questions we get most often before someone signs.
React Native or SwiftUI — which should I pick?
If you need iOS + Android with shared code, React Native (we use Expo). If you need Apple-grade polish, HealthKit-deep features, or expect 80%+ iOS users, SwiftUI. We'll recommend on the call.
How much do Apple and Google charge?
Apple: $99/year for the developer account. Google: $25 one-time. App Store + Play Store take 30% of digital purchases (15% if you're under $1M/yr through Apple's small-business program). These are not paid to us.
How long until my app is in the App Store?
Typically 5–7 weeks total. About 4–6 weeks of build + 1–2 weeks of Apple review. We optimize for first-pass approval — most of our submissions clear review in under 24 hours.
What if Apple rejects the app?
We respond to the reviewer, fix what they flagged, and resubmit. Most rejections are resolvable in 24–48 hours (privacy strings, screenshots, IAP test accounts). Rejection-handling is included in the price — no extra fees.
Can you do Android only?
Yes. React Native or Kotlin. Often cheaper because Google Play review is much faster and less strict than App Store.
