Six disciplines. One shipped app.
Platforms
iOS · Android · watchOS · Wear OS
Typical team
4–6 senior people
First build
Week 6
Native iOS
Swift and SwiftUI apps that feel like Apple built them — because they follow the same rules Apple does.
- Swift 6
- SwiftUI
- Swift Concurrency
- Core Data
- XCTest
We write Swift, not a wrapper around a web view. That means real 120Hz scrolling, real gesture physics, and access to the parts of the platform that make an app feel native: widgets, Live Activities, App Clips, Shortcuts, background refresh, and Watch companions. Every build ships through TestFlight with a review-ready privacy manifest.
What you get
- SwiftUI + UIKit interop
- Widgets & Live Activities
- App Clips & Shortcuts
- watchOS companion apps
- TestFlight release trains
- App Review preparation
Native Android
Kotlin and Jetpack Compose builds that hold up across the full spread of real devices, not just the flagship.
- Kotlin
- Compose
- Coroutines
- Room
- Hilt
Android is not one device — it is a distribution. We build in Kotlin with Compose and Material 3, then test against the low-end hardware your users actually carry. Baseline profiles, R8 shrinking and strict frame budgets keep the app fast on a four-year-old midrange phone, and Play Console staged rollouts mean a bad build never reaches everyone.
What you get
- Jetpack Compose UI
- Material 3 theming
- Baseline profiles
- Wear OS companions
- Play staged rollouts
- Device-lab QA matrix
Product design
Research, interaction design and a design system your engineers can actually build from.
- Figma
- Design tokens
- Rive
- Maze
Design here is not a set of pretty screens handed over a wall. We run discovery interviews, map the flows, prototype the hard interactions in code, and deliver a tokenised design system wired to the same components the app ships with. Light and dark are designed together, and every state — empty, loading, error, offline — is specified before a line of production code exists.
What you get
- Discovery & user interviews
- Interaction prototypes
- Tokenised design system
- Light + dark specification
- Accessibility audit (WCAG 2.2 AA)
- Motion specification
Backend & APIs
The sync engine, the API and the infrastructure the app leans on when the network is bad.
- TypeScript
- Postgres
- gRPC
- Firebase
- AWS
Most mobile apps fail at the seam between device and server. We build offline-first data layers with conflict resolution, typed API contracts shared between platforms, and push infrastructure that degrades gracefully. If you already have a backend team, we integrate with them and document the contract; if you don't, we build it.
What you get
- Offline-first sync engine
- Typed API contracts
- Push notification infra
- Auth & biometric sessions
- Observability & alerting
- Load & soak testing
Launch & store strategy
Submission, review, phased rollout and the store listing work that decides your install rate.
- App Store Connect
- Play Console
- Sentry
- RevenueCat
Getting approved is the low bar. We prepare the listing copy, screenshots and preview video, set up store experiments, and run phased rollouts with crash gates so a regression stops at 5% of users instead of 100%. We have handled expedited reviews, rejection appeals and privacy-label disputes often enough to know where the traps are.
What you get
- App Store & Play submission
- Listing copy + screenshot sets
- Store A/B experiments
- Phased rollout with crash gates
- Privacy labels & data safety
- Launch-week war room
Ongoing engineering
A standing team that keeps the app current through every OS release, every quarter.
- Fastlane
- GitHub Actions
- Firebase Crashlytics
- Linear
An app is never finished. iOS and Android each ship a major version every year, and both routinely break things. Our retained teams handle OS migrations, dependency upgrades, performance regressions and the steady flow of new features — with a fixed monthly cost and a roadmap you control.
What you get
- Annual OS migrations
- Performance budgets
- Feature roadmap delivery
- Crash triage SLAs
- Quarterly product reviews
- Handover-ready documentation
Three ways in, priced openly.
Launch sprint
from $68k
10–14 weeks
One platform, one clear job to be done, in the store and in front of real users.

- Annual OS migration cover
- Crash triage SLA
- Quarterly product review
The things clients ask first.
Not here? Ask us directly — you will get an engineer, not a sales team.
Because you told us the app matters. Cross-platform is a genuine fit for content-led apps with simple interaction, and we will say so if that is your situation. But the moment you need real gesture physics, deep OS integration, background work that survives, or 120Hz scrolling through a large data set, native stops being a preference and starts being the only thing that works. We would rather turn down a project than build it on the wrong foundation.
You will have a clickable prototype inside three weeks and a TestFlight or internal-track build you can run on your own phone by week six. From there, builds land every week. We do not do the six-month reveal.
You do — outright, from the first commit. Work happens in your repository where possible, or in ours and transferred at each milestone. There are no licence fees, no proprietary framework you are locked into, and no charge to leave.
Often, yes. We start with a paid two-week audit: architecture, crash data, performance traces, dependency health and store metrics. You get a written assessment and a costed plan for repair or rebuild. If the honest answer is that the existing codebase is fine and you need something smaller than us, the audit says that too.
We handle it, and it is included. Rejection is a normal part of shipping, not an emergency. We prepare submissions to avoid the common triggers, and when something is flagged we write the appeal, make the change or take the call with Apple.
Yes. We work under NDA as standard, and our engineers have delivered under HIPAA, SOC 2 and PCI-adjacent constraints. Security reviews, penetration testing coordination and access controls are part of the engagement, not an add-on.
