ReverseBits

Mobile apps engineered for the users you keep.

Watching day-7 retention drop? We build mobile apps where onboarding, push cadence, and crash recovery are engineered before launch - not patched after the 2-star reviews start rolling in.

How mobile engagements begin

Four situations we recognize by the second sentence.

Most mobile engagements with us start in one of four shapes. If you see yourself below, we already have a strong opinion about how the next twelve weeks go.

01

"We have a web product and customers keep asking for an app."

The decision isn't really "build an app" - it's "build the right app for the use case." A read-mostly web product with desktop-style flows usually needs a slim companion app, not a full port. Field workflows and on-the-go contexts need native; back-office workflows almost never do. We start with a use-case audit before any code.

Typically ships

  • Use-case audit
  • Platform recommendation
  • Companion vs full-port decision
  • MVP scope

02

"Our existing app has 2-star reviews and we don't know where to start."

Crash rate, retention curve, store reviews, telemetry - looked at together, the fix path becomes obvious in week one. Sometimes it's a six-week stabilization sprint; sometimes the codebase is too far gone and a controlled rewrite is cheaper than incremental patching. We don't recommend the rewrite by default - only when the math says so.

Typically ships

  • App audit
  • Crash deep-dive
  • Stabilization plan
  • 60-day improvement plan

03

"We're choosing between native, Flutter, and React Native - the team can't agree."

The choice depends on use case, hiring market, animation requirements, and platform-API depth. Most arguments online are technology-first; ours are use-case-first. For most B2B field-ops apps in 2026, cross-platform wins. For consumer apps with heavy interaction, native still does. We bring the framework, not the religion.

Typically ships

  • Decision framework
  • 3-year TCO projection
  • Proof-of-concept
  • Hiring guidance

04

"Day-7 retention is dropping and we don't know why."

Onboarding analytics, push cadence analysis, crash-on-cold-start incidence, store review sentiment scan. The diagnostic runs about three weeks. Then a focused retention sprint - better onboarding, recovered crashes, push opt-in optimization. We've seen apps move from 15% to 35% day-7 retention with the right surgical changes.

Typically ships

  • Retention diagnostic
  • Onboarding rebuild
  • Crash-recovery work
  • Push opt-in optimization

Our process

Five steps from idea to App Store and Play Store.

Built around store review timelines, device fragmentation, and OS update cycles. Click through to see what gets produced at each stage and the artifacts you walk away with.

Scope the app, decide the platform.

Feature list mapped against the native-vs-cross-platform decision framework. End of week one: a platform recommendation, three-year TCO projections for both paths, and hiring implications for each.

Frequently Asked Questions

The questions clients ask before choosing a mobile architecture, budget, and launch plan.

Ask a Question ->

The choice depends on use case. Native (Swift/SwiftUI for iOS, Kotlin/Compose for Android) wins for consumer apps with heavy animation, deep platform-API integration (ARKit, HealthKit, CarPlay, Wear OS), and where the engineering team is already platform-native. Flutter wins for design-heavy apps where pixel-perfect parity across platforms matters; the Skia rendering layer gives consistent UI everywhere. React Native wins where the team is already JavaScript-fluent and the app is data-display-heavy rather than animation-heavy. For most B2B field-ops apps in 2026, cross-platform is the right call. For premium consumer apps, native still has the edge.
