Mobile App DevelopmentiOS & ANDROID
The demo is the easy part. What decides whether an app lasts is the review queue, the four-year-old mid-range Android, and the tunnel where the network drops mid-sync. We design for those conditions from the first sprint, not the last one.

Native iOS in Swift and SwiftUI, built against the current SDK and tested on the oldest OS version you still support. App Review is planned for, not discovered: privacy manifest, permission strings and screenshots ready before submission.
Kotlin and Jetpack Compose, targeting the API levels Play actually enforces. We test on the mid-range hardware most users carry rather than the flagship in the office, and use staged rollout so a bad build reaches a fraction of them.
One codebase for iOS and Android, which suits apps that are mostly screens, forms and API calls. We say so when it doesn't: heavy media, sustained background work and deep OS integration still argue for native.
Flutter draws its own widgets, so the interface behaves the same on both platforms and animation stays under your control. The trade-offs are a larger binary and a smaller Dart hiring pool — worth it for design-led products.
The pragmatic choice when your team already writes TypeScript. The New Architecture removed most of the old bridge overhead; anything the framework doesn't reach still gets a native module written for it.
Design that accounts for thumb reach, safe areas, dynamic type and dark mode — and for the loading, empty and error states that decide how an app feels on a bad connection.
Apps that have to live inside an existing IT estate: single sign-on, MDM distribution outside the public stores, offline-first data with a defined conflict-resolution rule, and audit trails. Regulatory scope is agreed per engagement.
Mobile apps decay if left alone. Every OS release deprecates something, dependencies drift, and store policy moves. We watch crash-free sessions and ANRs, ship fixes on a schedule, and keep the build signed and green.
Undecided on native versus cross-platform?
Tell us what the app has to do and who uses it. We will say native or cross-platform, and explain what that choice costs you.
Launch is the middle of a mobile project, not the end. Two OS releases a year, store policy that moves under you, and a device mix nobody controls. The app needs a team that treats all of that as ordinary work rather than an emergency.
People who know where the two platforms diverge — background execution, permission prompts, push delivery, and the reasons App Review sends a build back.
Sprints end with a build on your device, not a screenshot. Feature flags keep unfinished work off the release branch, so shipping never waits for the slowest ticket.
A data layer kept separate from the UI, modules with boundaries you can enforce, and sync logic that stays put when a screen gets redesigned.
We set budgets for cold start, dropped frames and battery drain, then measure them on mid-range devices. A profile taken on the newest flagship proves very little.
Certificate pinning, secrets kept out of the binary, tokens in Keychain and Keystore, biometric unlock where it earns its place. Designed to support the obligations your sector places on you; scope agreed per engagement.
A named team after release: crash triage, OS betas tested before users get them, store policy changes handled, and a response window written into the agreement.
We pick the stack per project rather than by habit. The framework follows what the app has to do, the devices it runs on, and who will maintain it a year from now.

Seven steps. What matters is less the sequence than what each one has to produce before the next can start.
Step 01
Who uses the app, on what hardware, and under what network conditions. We agree what working means — and how it will be measured — before anyone opens an editor.
Step 02
The platform decision, the architecture behind it, and the cut line for version one. Anything that can wait for a later release is named as such now rather than argued about in week ten.
Step 03
Flows and screens, plus the states most designs skip: first launch, empty list, no signal, permission denied, and the moment two devices disagree about the same record.
Step 04
Two-week sprints, review on every change, and a signed build reaching TestFlight and the Play internal track from the first week — not the last.
Step 05
Automated runs on a device farm plus manual passes on older hardware and the next OS beta. We test airplane mode, backgrounded processes and expired tokens, because that is where mobile apps actually break.
Step 06
Submission with metadata, privacy declarations and screenshots prepared in advance, then a staged rollout that starts small and halts the moment crash rates move.
Step 07
Crash and ANR triage, OS upgrades tried against the beta, dependency updates, and a next release shaped by what analytics show people do rather than what the roadmap assumed.
Every sector puts different pressure on a mobile app — how sensitive the data is, how bad the network gets, how sharp the traffic peaks, how long a session lasts. The build follows those, not a template.
Patient apps, telemedicine and remote monitoring — built around how PHI is stored on the device, when a session expires, and what the audit trail records. Designed to support the HIPAA obligations scoped for the engagement.
Banking, payments and wallets, where device attestation, tamper checks, step-up authentication and a session that really expires matter more than the animation curve.
Storefronts that stay quick on a weak connection: image budgets, cached catalogues, a cart that survives a backgrounded app, and a checkout that fails safely.
Learning apps with lessons that download for the commute, progress that syncs once signal returns, and playback that keeps its place across devices.
Driver and warehouse apps that keep working in a dead zone: queued scans, background location within the platform's limits, and a sync that resolves conflicts rather than dropping them.
Live scores and fan apps built for spikes — push at volume, sockets that reconnect cleanly, and a feed that degrades rather than hangs when the whole stadium refreshes at once.
Media-heavy listing apps: prefetching, map clustering that survives a thousand pins, virtual tours, and lead capture that works before anyone creates an account.
Booking and itinerary apps that hold their data locally, because the airport is exactly where roaming stops and the boarding pass is still needed.

A developer reads it, not an auto-responder. Expect questions about scope and constraints first, then a suggested way to start.
