iOS, Android and cross-platform builds in React Native, Flutter, Swift and Kotlin. Offline-first, payment-ready, push-instrumented and launched to the store with your branding intact.
There is no universally right answer. The right one is the one that ships your business goal in your timeline at your budget. We help you pick honestly.
Our default for most product apps. One JavaScript codebase, near-native performance, huge ecosystem and faster releases.
Best when you want pixel-perfect custom UI that looks identical on both platforms. Strong for content, education and finance apps.
When you need every drop of performance, deep platform APIs, AR/ML pipelines or hardware-tight integration. Two codebases, two teams, premium output.
No hidden line items. Every Spacemen mobile build ships with these capabilities engineered in, not as "future scope".
If your app freezes the moment connectivity dips, you lose Indian commuter users, US field reps and African market users in the same week. We design every flow assuming the network might fail and recover.
We profile every release on a real low-end Android (Redmi 9, Nokia C) and an older iPhone (SE 2nd gen). If it crawls there, we fix it before shipping.
Most rejections are mundane: missing privacy policy, IAP misconfigured, login required for review. We pre-screen for every common rejection reason and get launches through in cycle one.
Workshops, persona work, competitor teardown and a clear native-vs-cross-platform recommendation backed by your real constraints.
Clickable Figma prototype, platform-specific (Material 3 + iOS HIG) refinements, dark mode and accessibility audit.
Two-week sprints with internal TestFlight and Internal Testing track builds every Friday. Real devices, real testers, real feedback.
Manual on 8+ device tiers (low-end Android, mid Android, high Android, iPhone SE, iPhone 14, iPhone 15 Pro, iPads, tablets). Automated UI tests on Detox or Maestro.
Metadata, screenshots, privacy labels, ATT prompts, IAP configured, Sign-in with Apple. Reviewer demo account, walk-through notes.
Staged rollout, crash monitoring, key-funnel analytics, fast hotfix releases. Monthly product reviews on real data.
If your team can hire JavaScript engineers and you have a web app already, React Native. If you need pixel-identical UI on both platforms or you have a Dart-curious team, Flutter. If your product needs heavy ML, AR or hardware integration, go native. We give you a written recommendation in week 1.
A lean MVP (auth, 4 to 6 core screens, push, payments) takes 10 to 14 weeks for both platforms on React Native or Flutter. A mid-complexity app (offline sync, advanced animations, IAP) takes 16 to 22 weeks. Native two-platform builds typically take 30 to 50% longer because of dual teams.
MVP cross-platform app: $28,000 to $58,000. Mid-complexity cross-platform with offline + payments: $60,000 to $130,000. Native iOS + Android with advanced features: $120,000 to $280,000+. We send a written fixed-bid quote within 48 hours of the discovery call.
Yes, end-to-end. We provision your Apple Developer and Google Play accounts (or work with your existing ones), prepare metadata, screenshots, privacy labels, demo accounts and submit. We've shipped 38 apps with zero rejections in the last 12 months.
Yes. We integrate via REST, GraphQL or gRPC, and we'll write any thin adapter layers needed. If your backend doesn't have mobile-friendly endpoints yet, we can build that BFF (Backend for Frontend) layer too.
You choose: hand over to your team with 30 days hyper-care, ongoing SLA-backed maintenance retainer, or a continued squad for monthly feature releases. Apple SDK updates twice a year, Android once a year, so most clients keep a small retainer.
