EXPERTS · MOBILE APP DEVELOPMENT

A mobile team that ships apps your users actually keep.

Full-native iOS and Android by senior mobile engineers with App Store + Play Store scars. MVPs, v1 launches, million-user products. Swift, Kotlin, and React Native when it genuinely fits.

A 30-minute discovery call. TestFlight + Play Internal plan on day one.

WHAT WE BUILD

Every kind of mobile build under one senior team.

Weekend-side-project MVPs to consumer apps at scale. We ship the code and the store submission.

Native iOS apps

Swift, SwiftUI, Combine. Tuned for iPhone + iPad, App Store review notes memorised. First-submission approval is the target.

Native Android apps

Kotlin, Jetpack Compose, Room, WorkManager. Tuned for Material 3 + Play Store Data Safety declarations.

Cross-platform builds

React Native or Flutter when the trade-off makes sense. We say early which side of the line your project sits on.

Store submission + ASO

App Store + Play Store review, screenshots, App Store Optimisation basics, review-team responses handled end-to-end.

Migrations + rewrites

Half our work is extending existing Swift, Kotlin, or React Native codebases. Audit first, quote second.

Tablet + wearable

iPad split-view, Apple Pencil, Wear OS, watchOS. Native, not shrunk. Feature-parity with the phone build.

PROCESS · HOW WE DELIVER

From wireframe to App Store, without the review-week panic.

Every mobile engagement follows the same rhythm. Written brief signed off before code. Weekly TestFlight + Play Internal builds.

  1. STEP 01 · DISCOVERY

    Understand the platform choice, not just the ask.

    A 30-minute call to unpack scope, target platforms, monetisation, and launch timeline. We say early whether native or cross-platform fits.

  2. STEP 02 · SCOPE

    Written brief with TestFlight plan + screenshot spec.

    Deliverables, milestones, timeline, price, TestFlight and Play Internal Testing plan, App Store screenshot spec, all upfront. Signed off before code.

  3. STEP 03 · BUILD

    Weekly TestFlight builds. Biweekly stakeholder demos.

    New build every week in TestFlight and Play Internal Testing. Biweekly stakeholder demo. Slack channel with the engineers writing the code. No account-manager telephone game.

  4. STEP 04 · SHIP

    Store submission, launch monitoring, 30 days support.

    We handle the submission, respond to review notes, and stay on-call for 30 days post-launch. Every version is roll-backable. Optional monthly retainer from month 2 for OS-update coverage.

STACK · NATIVE BY DEFAULT

The stack that fits your app.

Native by default. Cross-platform when the trade-off is real and we can defend it. Half our work is inside your existing app.

iOS

Swift · SwiftUI · UIKit · Combine · Core Data · WidgetKit

ANDROID

Kotlin · Jetpack Compose · Room · Retrofit · WorkManager · Hilt

CROSS-PLATFORM

React Native · Flutter · Expo · (case-by-case, never the default)

BACKEND

Node.js · Laravel · Firebase · Supabase · GraphQL · REST

REAL-TIME

WebSocket · APNs · FCM · WebRTC · Server-Sent Events

ANALYTICS

Amplitude · Mixpanel · Firebase Analytics · Segment · Sentry

ENGAGEMENT MODELS

How we work together.

Every mobile engagement starts with a 30-minute discovery call. We match the model to your scope, not the other way around. Numbers land in the written brief, not on this page.

DEFINED SCOPE

Fixed-price project

Best for a defined MVP or v1 scope.

8 to 20-week timeline. TestFlight + Play Internal builds weekly. Store submission included. First-submission approval is the target. Missed milestones on us. 30 days of post-launch support included.

ONGOING APP

Retainer engagement

Best for ongoing app + OS-update work.

Dedicated senior mobile engineer, 40 hours per week, embedded on your Slack. iOS + Android beta programs enrolled from day one so breaking changes surface before your users see them.

AUDIT / ADVICE

Hourly consulting

Best for store submission or code audits.

No minimum, no commitment. Common for pre-launch code audits, App Store rejection triage, native-vs-RN feasibility calls, and store-listing rescues.

You keep the discovery call brief + technical audit even if you never engage further.

COMPLIANCE + SECURITY

Store-ready + enterprise-ready by default.

Every mobile build ships to the standard the platforms and your auditors actually check. Not bolted on before a review.

App Store guidelines

We know the review notes and design to avoid rejections. First-submission approval is our target and our track record.

Play Data Safety

Full declarations, permission audit, and target-SDK compliance before every submission.

OWASP MASVS

Mobile Application Security Verification Standard baseline built in from day one, not audited after.

SOC 2 Type II

Same infrastructure standard as our web builds. Access controls, audit trail, encrypted storage at rest + in transit.

GDPR + region-locking

In-app consent flows, data export, right-to-delete, and platform-native permission dialogs. Region-locked data residency on request.

HIPAA + biometric auth

For health-tech + fintech clients: encrypted storage, KeyChain / KeyStore-backed keys, FaceID + BiometricPrompt, BAA support.

Common questions from mobile-app discovery calls.

Every engagement starts with a 30-minute discovery call. We understand your platforms (iOS, Android, or both), monetisation, and launch timeline, then follow up with a written brief and a fixed price. MVPs and v1 launches: 8 to 20 weeks. Store review adds 1 to 2 weeks. 30 days of post-launch support included. Full source, keys, and store accounts stay yours.

Native by default. React Native and Flutter are legitimate choices when the trade-off makes sense (content-heavy apps, tight timelines, small teams). We say early which side of that line your project sits on and defend the recommendation. Half our mobile work is also extending existing Swift, Kotlin, or React Native codebases. Audit before we quote.

Yes. Full submission, screenshots, App Store Optimisation basics, and review-team responses. First-submission approval is our target and our track record. If a build gets rejected we fix the review notes and resubmit at no extra cost. Post-launch OS-update coverage is an optional retainer; every project ships enrolled in iOS + Android beta programs.

Included by default when the app needs it. Same senior team, same Slack channel, no handoff between mobile and web. We handle FaceID / BiometricPrompt, KeyChain / KeyStore, SSO (SAML / OIDC), and SIEM-piped audit trails for regulated apps (fintech, health-tech, gov). See /experts/web for backend-only engagements.

Distributed across 10 timezones. Enterprise engagements get overlapping coverage in your working hours; smaller projects use async handoff with weekly TestFlight + Play Internal builds. Yes to audits, refactors, and rewrites of existing app codebases. Audit before quote so both sides know what we are walking into.

READY WHEN YOU ARE

Ship on iOS and Android without the review-week panic.

A 30-minute discovery call. Bring your Figma or your napkin sketch. We give you scope, timeline, and an honest read on native vs cross-platform.

You keep the audit + written brief even if you never engage further.
