Ship your mobile app before the market moves on.
Bring your mobile app to life. Wireframes, half-built prototypes, even napkin sketches built and shipped to the App Store and Play Store. Flat-fee milestones, founder-operated, React Native first with native depth when the platform demands it. You launch; we leave you a team that can keep shipping.

Your first checkpoints
A typical Build cadence. Every engagement is scoped individually. This is the shape of the first checkpoints, in order, so you know what progress looks like.
Kickoff
Access, architecture, and the plan in writing
NDA signed, repo access provisioned, tooling wired in, and the first architectural decision records written. You see the plan before we write any code.
Foundation
The core shipped, running on real infrastructure
Auth, data model, and the first production-ready screens live against a real backend. CI, crash reporting, and analytics wired in from commit one.
Sprint rhythm
Feature sprints with weekly demos
Real features shipping to staging every sprint. Weekly demo to your team. Scope frozen per milestone so you always know what's in the next release.
Beta
TestFlight or closed beta in your first customer's hands
Feature-complete, crash-free, beta testers onboarded. Monitoring live. Apple and Google review-ready.
This is the shape, not a hard promise. Your timeline is confirmed in writing at proposal, and the only thing that moves it after that is a scope change.
Who we build for
Founders and teams shipping new iPhone, Android, tablet, or wearable apps backed by production infrastructure and launched to the App Store and Play Store.
Post-idea founders
You have a wireframe, a Figma file, or a half-working prototype. You need a small, senior team that can take it to the App Store and Play Store without churn.
Funded startups post-seed
You raised to build a mobile product and you can't afford to lose six months to contractor hand-offs. You need senior hands on the architecture from day one.
Web platforms adding mobile or wearable
Your web product works. Customers are asking for a mobile or wearable companion. You need the expertise to ship it without hiring a whole team.
Platforms and stacks we build on
Frontend through backend. React Native first; Swift and Kotlin when platform depth matters. Tablet and wearable are first-class surfaces, not add-ons. We build the API, database, auth, and cloud infra the app needs to run.

How we build
Discovery, design, build, launch, care. Scope and architecture decisions explained at every step.
Discovery
We scope the problem, the users, the constraints, and the launch target. You get a written plan, architecture decisions included, before we write any code.
Design & architecture
Wireframes, data model, API contracts, third-party integrations, and the platform mix (React Native vs native, phone vs tablet vs wearable). Every decision documented.
Build
Sprint-based development with staging builds, internal TestFlight and Play Console alphas, and weekly demos. Tests, monitoring, and release QA baked in from commit one.
Launch
App Store and Play Store submission, provisioning, privacy manifests, marketing assets, and launch-day monitoring. We've done this across consumer, enterprise, and regulated apps.
Care
Post-launch monitoring, crash triage, bug fixes, and the first follow-up release inside a 30-day stability window. Optional handoff to a Partner retainer for ongoing ownership.
Mobile development
React Native first. Swift and Kotlin when hardware depth wins.
React Native is the default because it's the fastest path to a shipped product on iOS and Android with a small team. We reach for native Swift / SwiftUI or Kotlin / Jetpack Compose when the app needs platform-specific depth (ARKit, CoreML inference, background services, complex animations, battery-sensitive flows) or when the team maintaining it post-launch already knows native. Either way we own the App Store and Play Store submission end-to-end: provisioning, privacy manifests, review responses.
- React Native + Expo (default) with a shared TypeScript codebase
- native iOS (Swift, SwiftUI) and Android (Kotlin, Jetpack Compose) when depth matters
- Biometric auth, offline-first data, and background processing
- App Store and Play Store submission, privacy manifests, TestFlight
- Monitoring, crash-free session tracking, and release QA
- AI integrated through production SDKs when it saves the user time, never as a gimmick
Tablet development
iPad and Android tablet as first-class surfaces, not a phone screen stretched.
Tablets are where clinicians, operators, and field teams actually do the work. We build iPad and Android tablet experiences designed for the form factor: split view, drag-and-drop, multitasking, keyboard and pencil input, and large-screen layouts that scale instead of break. When a product needs both phone and tablet, we design the tablet surface early so the app doesn't feel like a scaled-up phone at launch.
- iPad (SwiftUI + UIKit) with split view, drag-and-drop, and Scene-based multitasking
- Android large-screen and foldable layouts (Jetpack Compose window size classes)
- Apple Pencil input and iPad keyboard shortcuts
- React Native with responsive layout for teams shipping phone + tablet on one codebase
- Tablet-first UI patterns: master/detail, side navigation, multi-column lists
- App Store and Play Store submission with tablet-specific metadata and screenshots
Wearable & immersive development
Apple Watch, Galaxy Watch, Meta Quest, and Apple Vision Pro: designed for the wrist or the headset, not shrunken from the phone.
Wearables and immersive devices are a product differentiator, not an afterthought. Workout context, medication reminders, glanceable status, quick actions. We build watchOS and Wear OS companions that integrate with HealthKit, Health Connect, and paired-phone data. On the immersive side, we take on Meta Quest and Apple Vision Pro projects for training, simulation, and spatial workflows, usually wired back to a production backend so session data actually lands where the team can see it.
- watchOS (Swift + SwiftUI) with complications and glanceable UI
- Wear OS (Kotlin + Jetpack Compose) with Tiles and ongoing notifications
- HealthKit, Health Connect, and paired-phone handshakes that survive airplane mode
- Battery-conscious background processing and always-on display
- Meta Quest and Apple Vision Pro (Unity, Unreal, visionOS + RealityKit, WebXR)
- Cross-device data sync back to a production backend
Legacy-to-Modern Rebuild
When maintaining your old stack is slowing the team down.
Your product works. The stack is the problem: Xamarin on a deprecated runtime, Objective-C on an iOS codebase nobody will touch, cross-platform gone wrong, or a web-only product when your customers want mobile. We move you off the old stack cleanly: phased plan, rollback checkpoints, architectural decision records, and your team trained on the new stack before we leave. A migration only counts as successful if you don't need us after handoff.
When it fits
- Xamarin → React Native or native
- Objective-C → Swift
- End-of-life React Native versions → modern RN + Expo
- Web-only product → native mobile or wearable
- Deprecated SDK migrations that App Store or Play Console is forcing
What we deliver
- Modernization strategy and risk assessment
- Phased migration plan with rollback checkpoints
- The migration itself: platform, SDKs, architecture
- Architectural decision records for the new stack
- Team training on the new stack during the engagement
- Clean handoff, or continued ownership via a Partner retainer
Engagement shape
Fixed-scope project, flat-fee milestones with a deposit. Ends when the new stack is in production and your team is trained on it.
Different from Rescue
Rescue stabilizes something broken. Legacy-to-Modern Rebuild moves a working product onto a modern stack. Different buying motion, different deliverable, and they rarely happen at the same time.
