In short
Start with a responsive web app unless the product genuinely needs something only native provides: reliable push notifications on iOS, deep hardware access, offline-first operation, or an app-store presence because customers will look there. A web app runs on every device from one codebase, is found through search, needs no installation, and costs roughly a third to a half of building two native apps. Native wins for daily-use consumer products, hardware-dependent tools and anything users expect to find on their home screen. Progressive web apps cover much of the ground between.
What each one is
A web app is an application that runs in the browser: a URL, no installation, one codebase that adapts to phones, tablets and laptops. Modern web apps can be fast, work offline to a degree, and be added to a home screen. They are found by search engines, shared by link, and updated instantly for everyone.
A native mobile app is installed from an app store, built for iOS or Android specifically, and has full access to the device: camera, sensors, contacts, background processing, notifications, biometrics. It is faster for heavy interaction, works reliably offline, and lives on the home screen where daily-use products want to be. It is two codebases, or one cross-platform codebase with compromises, and two store review processes.
The four reasons to go native
1. Push notifications, reliably, on iOS. Web push exists on iOS since 2023 but only for apps added to the home screen, and adoption is low. If re-engaging users through notifications is central to the product, native is still the dependable route.
2. Hardware and system access. Camera pipelines beyond a simple capture, Bluetooth, NFC, background location, health data, biometrics, the file system, widgets, watch integration. Browsers expose some of these, inconsistently; native exposes all of them.
3. Offline-first operation. Field tools, anything used in transit or on sites without signal. Web apps can cache and queue, but genuinely offline-first behaviour with sync is far more mature on native.
4. Distribution and expectation. Some products are things people look for in the App Store, and some audiences treat an app-store presence as a credibility marker. Consumer products used daily benefit from the home-screen icon in a way a bookmark never matches.
If none of these apply, a native app is an expensive way to deliver what a URL would.
The reasons to stay on the web
Cost. One codebase instead of two or three. App development for native iOS and Android roughly doubles the front-end cost of a web app; cross-platform frameworks narrow the gap but do not close it.
Discovery. Web apps are indexed by search engines and shared by link. Apps are found through store search, which is weak, or through marketing, which is expensive. Most B2B products are found through the web and used at a desk, where the browser is the natural home.
No installation. Every install step loses users. A link that works is the lowest-friction path to a first use, which matters most for products that need to prove themselves before anyone commits.
Instant updates. No store review, no users on old versions.
Desktop. A web app runs on laptops as well as phones. A mobile app does not, and many products are used mostly at a desk.
Learning first. Shipping on the web reveals what people actually do; the native version can then be built for the parts that need it. Building native first commits to platform decisions before the product is understood.
The middle ground
Progressive web apps (PWAs) are web apps with a manifest and a service worker: installable to the home screen, able to work offline, with push on Android and, within limits, iOS. For many products they deliver most of what native would, from one codebase. Their limits are iOS's, where installation is less discoverable and some capabilities remain restricted.
Cross-platform native frameworks such as React Native and Flutter produce iOS and Android apps from one codebase with near-native performance. They suit teams that need the store presence and device access without maintaining two separate apps, at the cost of occasional platform-specific work and dependence on the framework.
Web view wrappers package a web app inside a thin native shell for store distribution. Cheap, and the stores increasingly reject apps that are nothing but a website; useful only when a real native layer is added around the web content.
A decision path
- Does the product need any of the four native capabilities? If not, build a web app.
- If it needs one or two, can a PWA provide them for your audience's devices? If yes, build a PWA.
- If it needs reliable iOS push, deep hardware access, or offline-first sync, or the audience expects an app store presence, go native.
- Going native, is there one platform that matters first? Ship that; add the second when the first has proved the product.
- Whatever you build, the back end, the data model and most of the logic are shared. Design them once.
Most businesses that ask this question should start on the web, and many of the ones that build a native app first spend the budget on a platform their customers use less than they assumed. The prototype-to-production path is far shorter on the web, and nothing built there is wasted if native follows. If you want a recommendation for a specific product, book a call; the four capabilities usually settle it in ten minutes.
Common questions
Is a web app cheaper than a mobile app?
Usually by a wide margin. A responsive web app is one codebase for every device; native iOS and Android are two, with two review processes and two sets of updates, roughly doubling the front-end cost. Cross-platform frameworks reduce the difference. The back end costs about the same either way.
Can a web app send push notifications?
Yes on Android and desktop browsers, and on iOS since 2023 only for web apps that have been added to the home screen, which few users do. If notifications are central to the product and iOS users matter, native remains the reliable route. For occasional or optional notifications, a progressive web app can suffice.
What is a progressive web app?
A web app with a manifest and a service worker that can be installed to the home screen, launch full-screen, cache content for offline use, and send push notifications where the platform allows. It delivers much of the native experience from a single web codebase, with limits on iOS around discoverability and some device capabilities.
Do I need an app for my business?
Only if it needs something the web cannot provide: reliable iOS push, deep hardware access, offline-first operation, or an app-store presence your customers expect. Most businesses are better served by a fast responsive website or web app that is found through search and needs no installation. Build native later for the parts that prove to need it.
Should I build for iOS or Android first?
Whichever your customers use, which depends on market and demographic: iOS dominates in the United States, the UK and among higher-spending consumers; Android dominates globally and in most price-sensitive markets. If the split is unclear, a cross-platform framework or a web app avoids choosing until the data arrives.
