Cross-Platform Mobile Engineering

Mobile Apps That Feel Truly Native on Every Device

We build iOS and Android applications using React Native and native tooling. Delivering performance-first mobile experiences that users rate highly and return to daily.

How We Build Mobile

Step 01
01

Mobile UX Design

Creating platform-specific wireframes and prototypes with separate iOS and Android considerations designed in from the start, not retrofitted later.

Step 02
02

React Native Engineering

Building a single codebase targeting both platforms with native module bridges wherever performance demands platform-specific precision.

Step 03
03

Device & OS Testing

Validating across a real device matrix, multiple screen sizes, OS versions, and manufacturer variations, before every release goes out.

Step 04
04

Store Submission & Launch

Managing end-to-end App Store and Play Store submission including screenshots, metadata, compliance checks, and rejection resolution.

Key Principles

How we build mobile apps that earn five-star ratings and daily active users

Mobile users are unforgiving. A slow transition, an unintuitive gesture, or a single crash at the wrong moment loses a user permanently. We build to the standard that top-rated apps set.

01

Platform conventions over custom patterns

iOS and Android users have learned expectations. We follow platform conventions by default and break them only when there's a meaningful reason to.

02

Performance profiled, not assumed

We profile render performance, memory usage, and battery impact throughout development, not just at the end before App Store submission.

03

Offline-first architecture by default

Mobile users lose connectivity. We design data sync, local caching, and optimistic UI patterns so the app works reliably regardless of signal.

04

App Store approval built into the process

Review guidelines, privacy manifest requirements, and content policies are part of our pre-submission checklist, avoiding costly rejection delays.

Solving the Toughest Mobile App Challenges

Mobile projects have unique failure modes. We've navigated all of them.

Phase 01

App Store Rejection

Launches delayed by weeks due to App Store rejections for policy violations, privacy issues, or performance problems discovered at submission.

The Incroft Solution

App Store compliance is a first-class requirement throughout development, privacy manifests, data usage declarations, and guideline checks happen before submission, not after.

Phase 02

Poor Retention After Install

Users download the app but don't return after the first session because the onboarding experience fails to communicate core value quickly enough.

The Incroft Solution

Onboarding flows designed to deliver the core "aha moment" within the first 60 seconds, with smart push notification strategies that bring users back.

Mobile Dev Knowledge Base

Mobile Development Questions

Do you build native or cross-platform apps?

expand_more

Primarily React Native for cross-platform efficiency. For performance-critical applications like real-time video or AR, we build native iOS (Swift) or Android (Kotlin) where it's genuinely warranted.

Do you handle App Store and Play Store submission?

expand_more

Yes. We manage the full submission process including screenshots, metadata, review responses, and any rejection resolution.

Can you add mobile to an existing web application?

expand_more

Yes. We regularly build mobile companions to existing web platforms, sharing API layers and business logic while delivering a truly native mobile experience.
