How to make the case for a mobile app at your company
Key Points
- Apps convert ~3x better than mobile web
- Push notifications drive major engagement uplift
- Expo + AI enables one-codebase shipping fast
Summary
This brief equips engineers to make a business-focused, data-backed case for building a mobile app. Users spend most smartphone time in apps (94% of time in apps vs 6% mobile web). Apps outperform mobile web on conversion (≈3x), retention, session length, and revenue per user. Native apps also unlock push notifications, offline support, device APIs (camera, GPS, biometrics), background processing, and better performance — all of which drive measurable business outcomes. Modern toolchains (Expo + AI-assisted development) reduce cost, timeline, and operational overhead by enabling one codebase, cloud builds, and OTA updates.
Key Points
- Start with the business problem, not tech: quantify current mobile web metrics (traffic, conversion, AOV, churn) and apply conservative uplift assumptions (use 3x conversion lift for apps as a baseline).
- Conversion & revenue: apps typically convert 3x better; shopping apps see ~20% cart abandonment vs ~85% on mobile web. App users often have 2.8–5x higher LTV.
- Engagement & retention: push opt-ins and well-timed notifications increase engagement 26–75% and can multiply purchase behavior; apps enable a direct, owned channel without ad spend.
- Native capabilities: offline access, camera/GPS/biometrics, background sync, and faster UX increase session length and unlock use cases impossible or fragile on the web.
- Market & vertical fit: mobile market is large and growing (mobile app market ~$298B in 2025); tailor the case to your vertical (e-commerce, finance, healthcare, education, field tools, etc.).
- Objections: cost and timeline are now addressable. With Expo (React Native) and AI-assisted code generation you can ship from one codebase, use cloud build services, and push OTA updates to iterate quickly.
Practical asks & checklist for engineers to present
- Measure: current mobile web traffic, conversion rate, AOV, cart abandonment, email open rates, and paid acquisition spend.
- Model: show revenue uplift by applying a 3x conversion multiplier and a range for LTV uplift (2.8–5x) to current metrics.
- Engagement plan: estimate push opt-in % and projected engagement/revenue uplift using 26–75% engagement benchmarks and the 384% purchase lift for well-timed notifications.
- Tech plan: propose using Expo + React Native to reuse web/React skills, list CI/CD and OTA workflows, and estimate timeline and cost (dev effort, maintenance savings vs native teams).
- Pilot scope: define an MVP with key native features (push, offline sync, payments/one-tap checkout, biometrics) and target metrics to validate within 6–12 weeks.
Bottom line
Present a quantified opportunity: convert existing mobile users at higher rates, reduce dependence on paid re-engagement, and unlock native features that materially improve retention and revenue. With Expo and modern AI tooling, the decision becomes how to build and iterate fast — not whether to build.
