What We Build

Core Mobile App Development Services

Full-lifecycle mobile engineering — from the first Figma frame to a five-star app store listing and every release after.

Native iOS & Android App Development

Swift and Kotlin builds that feel like they belong on the platform. Full access to cameras, sensors, biometrics, ARKit, widgets, and Haptics — with strict adherence to Apple HIG and Material 3 for App Store approval on the first submission.

Swift, SwiftUI, Kotlin, Jetpack Compose
Biometrics, camera, sensors, push, offline
First-submit App Store & Play Store approval

Cross-Platform App Development

Ship iOS and Android from a single codebase with React Native and Flutter — cut your build budget by up to 40% without sacrificing 60fps performance. Shared business logic, platform-tuned UI, and zero compromise on polish.

Why Brilworks

Mobile Engineers Who Ship Apps Users Actually Keep

We don't just push builds — we partner on every product decision that makes an app retain, monetize, and earn five-star reviews.

Top 3% Mobile Talent

Senior iOS, Android, React Native, and Flutter engineers filtered for clarity, shipping discipline, and problem-solving — not for time zone convenience.

4.8★ Average Rating

Our apps earn real user love on the App Store and Play Store — thanks to accessibility, onboarding, and post-launch optimization built into every sprint.

100+ Mobile Projects Delivered

A decade of shipping iOS and Android apps gives us pattern recognition — we anticipate App Store rejection reasons, Android fragmentation, and scaling traps before you hit them.

AI-Driven Development

We use AI to accelerate code review, crash triage, and QA — so engineering cycles stay focused on the product decisions that actually shape user retention.

Real 24/7 Availability

Overlapping time zones mean your build doesn't sit idle. Crash in production at 2AM? Someone on our team is already on it before you wake up.

App Store Compliance, Done Right

Privacy manifests, ATT prompts, data safety disclosures, App Tracking Transparency — we handle the policy landmines so your submission sails through on round one.

Client Stories

What Mobile Founders & Product Leaders Say

Not curated marketing quotes. Real words from real people who shipped real apps with us.

“Brilworks shipped our iOS and Android app in 14 weeks and both hit 4.9 stars on day one. App Store approval on first submission, Play Store rollout without a single rejection. They get mobile.”

David VelasquezCEO, Rastrack · 4+ year partnership

“Our React Native MVP went from Figma to TestFlight in under 4 weeks. We hit 250K downloads in the first 90 days and 72% day-7 retention. Their sense for what to build first saved us 6 months of rework.”

Liz BullenFounder, Lyfecoin · 2+ year partnership

“They rebuilt our legacy Objective-C app into Swift + Kotlin natives — crash rate dropped from 3.1% to 0.12%, cold-start time cut in half. The app store reviews flipped from 2.8 to 4.7 inside a quarter.”

GolanDirector of R&D, Trackimo · 3+ year partnership

Common Questions

Frequently Asked Questions

Everything founders and product teams typically ask before kicking off a mobile build with us.

We build for both iOS and Android using native (Swift, Kotlin) and cross-platform (React Native, Flutter) technologies. We select the approach that best fits your product requirements, performance needs, and long-term roadmap — and we tell you honestly when one approach will serve you better than the other.

We evaluate your feature set, performance expectations, integration needs, and roadmap. Heavy use of device capabilities (ARKit, complex camera, biometrics, background processing) usually points to native. If speed-to-market and shared code economics dominate, React Native or Flutter wins. We document the tradeoffs before you commit.

A focused mobile MVP ships in 12-16 weeks. Mid-complexity apps with multi-role workflows, payments, or real-time sync land in 4-6 months. Enterprise apps with deep integrations run 6-9+ months. You get a precise estimate within 48 hours of our first call.

Yes. Our designers ship user flows, wireframes, interactive prototypes, and pixel-perfect screens in Figma — tuned to Apple Human Interface Guidelines and Material 3. Onboarding, empty states, error states, accessibility, and dark mode are in scope from day one.

Yes. We prepare builds, write descriptions, generate screenshots, handle privacy manifests, App Tracking Transparency prompts, and Data Safety forms. We manage the entire App Store Connect and Play Console submission — and handle rejection rebuttals if they happen.

Yes. We audit your current codebase, surface crash hotspots and architectural debt, and either modernize in place (Objective-C → Swift, Java → Kotlin) or rebuild cleanly on a new stack. We've cut crash rates by 20x and cold-start times in half on legacy rebuilds.

Absolutely. We provide ongoing support covering bug fixes, OS compatibility updates (iOS 18, Android 15), performance optimization, crash monitoring via Sentry or Firebase Crashlytics, and continuous feature delivery. Most clients stay with us 12+ months post-launch.
