Mobile App Development
Mobile app development delivers a native or cross-platform application for iOS and Android that performs well on real devices and stays maintainable as your product grows.
Overview
A mobile app lives or dies on how it feels in someone’s hand: load time, offline behavior, and how naturally it fits each platform’s conventions. We build for that experience first.
Most products don’t need two entirely separate native codebases. We choose native or cross-platform deliberately, based on your performance needs and budget, not by default.
Engineering
Real Engineering Behind Every Mobile App Development Engagement
Mobile App Development work here follows the same disciplined process as everything else Fastly builds — discovery, architecture decisions made deliberately, and code written for your specific system, not adapted from a generic starter.
Business Problems We Solve
Two Platforms, One Budget
Supporting iOS and Android well feels like it requires two separate teams and two separate budgets.
Poor Offline Handling
The app becomes unusable the moment connectivity drops, frustrating users in the real world.
Inconsistent UX Across Platforms
The app feels like two different products depending on which device it’s running on.
App Store Submission Friction
Store review requirements and platform-specific rules slow launches down unexpectedly.
On Every Device
Built for the Phone in Someone's Hand
Every feature is engineered around how a real app is actually used, not how it looks in a demo.
Native & Cross-Platform Builds
The right approach chosen deliberately for your performance needs and budget, not a default.
Offline-First Data Sync
The app stays usable without a connection and reconciles data cleanly once it’s back online.
Push Notifications
Timely, relevant notifications that bring users back without becoming noise.
Secure Authentication
Modern authentication (including biometric options) built in from the start.
App Store & Play Store Readiness
Submissions prepared to each store’s current guidelines to avoid review delays.
Analytics Integration
Usage data wired in from launch so decisions after release are based on real behavior.
Delivery
Development Workflow
The same disciplined process behind every mobile app development engagement, from first conversation to production.
04 Steps
- 01
Discovery
Understanding your goals, users, and constraints before any code is written. Output: Technical Brief.
- 02
Strategy
Defining the technical approach, architecture, and roadmap for what gets built. Output: Architecture Plan.
- 03
Development
Building in focused iterations, with regular check-ins and working software at every stage. Output: Working Software.
- 04
Launch & Growth
Shipping to production, then monitoring, refining, and scaling based on real usage. Output: Production Release.

Consistent Brand Experience
The app feels like the same product everywhere it runs.
Faster Time to Market
A focused build process gets a real, usable app in front of users sooner.
Reliable on Real Devices
Tested against real-world conditions, not just a simulator.

Frequently Asked Questions
Should we build native apps or a cross-platform app?
It depends on your performance requirements and budget — cross-platform frameworks cover most products well, while native development suits apps with heavy device-specific performance needs. We recommend based on your specific case, not by default.
How long does mobile app development typically take?
It varies by scope, but a focused first release is scoped and planned during the Discovery phase of our process so there’s a clear, realistic timeline before development starts.
Does the app need to work offline?
If that matters for your use case, offline-first data sync is built in from the start rather than added later, since retrofitting offline support is far more disruptive.
Who handles App Store and Play Store submission?
Submission and store-readiness are part of the delivery process, prepared against each store’s current guidelines to avoid avoidable review delays.
