Mobile App Development 

Mobile app development for iOS and Android with React Native and Flutter: offline-first builds, store submission, and staged rollouts from one codebase.

iOS, Android, and cross-platform, done right

Two app stores, two review processes, one budget. Most products don't need two native codebases to handle that, which is why our default recommendation is React Native or Flutter: one codebase covering both platforms, with native modules in Swift or Kotlin only where a feature genuinely demands them. When a product does justify going fully native, we'll tell you that too, with the cost difference in writing.

Mobile has constraints that web teams tend to underestimate. Networks drop, so we build offline-first with local storage and background sync. Batteries drain, so background work gets budgeted. And store review can reject a finished app over a single permissions string, so we design against App Store and Play Store guidelines from the first sprint instead of discovering them at submission.

Releases run through proper mobile CI/CD: every merge produces a TestFlight or internal-track build, crash reporting is wired in before launch, and staged rollouts mean a bad release reaches 5% of users instead of all of them. After launch we keep watching crash-free rates and store reviews, because shipping the app is the midpoint of the project, not the end.

What We Build

End-to-end delivery

Cross-Platform Apps

React Native and Flutter builds shipping to iOS and Android from a single codebase.

Native Modules

Native Swift/Kotlin modules where performance or platform APIs demand it.

Offline-First Architecture

Local-first data sync for field teams and low-connectivity environments.

App Store Delivery

Release management, App Store/Play Store submission, and CI/CD for mobile.

Maintenance & OS Updates

Annual iOS and Android releases break things. Retainers cover OS and dependency updates, store policy changes, and crash triage, sized to your app.

Our Process

How we build

01

Discovery

Platform strategy (native, cross-platform, or hybrid) scoped to your actual requirements.

02

Design

Platform-native UX patterns for iOS and Android, not a single generic skin.

03

Development

Two-week sprints with TestFlight/internal-track builds for continuous feedback.

04

Launch & Support

Store submission, crash monitoring, and post-launch iteration.

Why RNDSOL

What makes this work

Right tool for the job

We recommend cross-platform or native based on your requirements, not our default stack.

Offline-capable by default

Field-service and low-connectivity use cases are a specialty, not an edge case.

Full store lifecycle

From first build to App Store review to post-launch crash monitoring.

Shared backend, less duplication

Mobile teams work off the same API layer as web: one source of truth.

Outcomes

What working with us looks like in numbers

1 codebase

Serving both iOS and Android, with native modules only where they earn their keep.

99.5%+

Crash-free session target before we consider a release healthy.

Weekly builds

TestFlight and internal-track builds from every sprint for continuous feedback.

Staged rollouts

New releases reach a small slice of users first, so problems stay small.

FAQ

Mobile Apps FAQs

Depends on your requirements. If performance-critical native APIs are central to your product, native. Otherwise, React Native or Flutter usually gets you to market faster at lower cost.

Yes, including compliance review prep, screenshots, and metadata.

A focused cross-platform MVP usually takes 10 to 14 weeks including store submission. Heavy offline sync, payments, or hardware integrations add time, and we flag that during discovery.

Yes. We start with a code and architecture audit, stabilize crashes and the release pipeline first, then move onto the feature roadmap once the foundation holds.

Usually, yes. Mobile apps built alongside our own API layer ship faster and break less, but we're equally comfortable integrating with a backend your team already runs.

A monthly retainer sized to your app: OS and dependency updates, store policy compliance, crash triage against the 99.5 percent crash-free target, and a small budget of improvement hours. Most apps need this from day one, because the stores don't stand still even when your roadmap does.
