Develop native and cross-platform mobile solutions for iOS and Android — from consumer apps to enterprise tools.
Native iOS, native Android, React Native, or Flutter — we pick the platform that fits the brief, not the trend. RunWhatMatters ships mobile apps that win App Store features, survive real-world device fragmentation, and earn the second session.
Mobile apps that earn the second session.
Most apps die on day 30. RunWhatMatters's mobile practice ships apps engineered for the metric that actually matters — the user who comes back on day 8, day 30, and day 90. We design for retention, build for the device that's three OS versions behind, and instrument the analytics that let your product team act on what users actually do.
The full mobile lifecycle, end to end.
From the App Store submission to the on-call rotation — we cover everything between.
Native iOS & Android
Swift, SwiftUI, Kotlin, Jetpack Compose. The platform-native work that lets the app feel like a citizen of the OS.
Cross-platform
React Native, Flutter, Kotlin Multiplatform. One codebase, two platforms — when the trade-off is right for the product.
App Store & Play Store
Submission, review handling, ASO, and the metadata work that gets the app discovered.
Mobile DevOps
Fastlane, Bitrise, GitHub Actions. CI/CD pipelines that ship to TestFlight and internal track on every merge.
Crash & performance
Crashlytics, Sentry, Datadog Mobile RUM. The observability that catches the Android-specific crash on the device no one owns.
Mobile security & compliance
Certificate pinning, jailbreak detection, secure storage, HIPAA-grade patterns for healthcare apps.
The right framework for the right problem.
We work across the mobile ecosystem — and we'll tell you when each one makes sense.
The work. The numbers.
An anonymized case from our files. The client, the problem, the engineering, and the measurable result.
A legacy patient engagement app with 12% monthly active users, a 2.1★ App Store rating, and patient complaints that drove 40% of support tickets. The existing vendor had missed two relaunch dates and couldn't fix the retention crisis.
RunWhatMatters rebuilt the app in React Native with a personalization engine powered by on-device ML, push notification strategy informed by behavioral data, and a redesign driven by 60 patient interviews. Submitted and managed the App Store / Play Store relaunch.
"We had written off mobile. RunWhatMatters proved us wrong in fourteen weeks and the app is now the most-used surface in the entire health system."
— Sandeep Kapoor, VP Digital Health
From idea to App Store.
A 12-week arc that takes you from a Figma file to a 5-star-reviewed production app.
Discover
User research, platform analysis (native vs. cross-platform), ASO landscape. The decisions that lock in 2 years of architecture.
Design
iOS HIG, Material You, motion principles, and the design system that scales across screens.
Build
Component-first development, automated testing on real devices, TestFlight from week four.
Launch & iterate
Store submission, ASO optimization, crash monitoring, and the post-launch iteration loop that compounds retention.
Mobile is the front door, in every industry.
From the patient-facing health app to the field-service technician's tablet — mobile is where the work happens.
Three ways to work together.
We pick the model that matches your brief. Every engagement starts with a written estimate and a no-surprise SOW.
Fixed-Fee
Well-scoped builds with a clear deliverable.
A defined SOW, fixed price, fixed timeline. Best for audits, MVPs, replatforming, and any engagement where the deliverable is well understood.
Time & Materials
Exploratory or platform work, billed monthly.
A senior team at a transparent rate, with a quarterly roadmap. Best for fractional CTO, ongoing platform partnerships, and exploratory AI/data work.
Equity + Cash
For select early-stage founders.
Reduced cash burn in exchange for equity — capped at 5% and only for ventures we would invest in ourselves. We do three of these per year.
The deliverable. Not the pitch deck.
Every RunWhatMatters engagement ends with these six things. We don't ship without them.
The questions we hear most.
Specific to mobile development — and answers your AI assistant can quote.
What is mobile app development?
Should we build native or cross-platform?
How long does a mobile app take to build?
How much does mobile app development cost?
Do you handle App Store submission and ASO?
Have an app idea — or an app to revive?
Book a 30-minute working session with a RunWhatMatters mobile principal. Bring the brief, the design, or the legacy code. We'll come back with the path to App Store.
