Web App vs. Mobile App: How to Decide

Who will use it, and how often?

Usage frequency is the strongest signal. Products people open daily earn a place on the Home Screen; products people open a few times a year do not.

Phones are an app-heavy medium. eMarketer estimated that US adults spent about 90% of their smartphone internet time inside apps rather than the mobile browser, as reported by InfoDocket, 2020. That figure is dominated by social, video, audio and messaging, the products people return to many times a day. It does not mean your invoicing portal or booking tool will earn the same habit.

Ask three questions. Will your users return at least weekly? Is the product part of a routine (workouts, banking, a team's shift schedule)? Will they open it on a phone in the moment, rather than at a desk? Three yeses lean native. Three nos lean web. A mix usually means a web app that works well on phones.

Also consider who has to install it. A customer who needs a quote once will not download an app for it. A field crew your company manages will install whatever you tell them to. Internal tools and B2B portals lean web because there is no install step, and one link works for everyone.

Which device features do you need?

The browser now covers camera, microphone, geolocation, offline storage and basic push. Native still wins on background location, Bluetooth peripherals, health data and anything that must run when the app is closed.

Google's web.dev PWA capabilities guide lists geolocation, camera, microphone, sensors and biometric authentication as broadly available. Bluetooth LE, NFC, USB, background sync and push notifications are marked as limited-support, and the same guide warns that you "should not expect your app to work the same way on every device." Treat that as the planning rule: check each feature on the exact devices your users own.

Push deserves a closer look because it is the feature people most often assume is missing. Apple's WebKit team confirmed in its iOS 16.4 web push announcement that web push on iPhone is available only to web apps added to the Home Screen, and only after the user grants permission through a direct tap. It works, but it has more friction than a native opt-in prompt. If reminders drive your business model, that friction matters.

How will people find it?

A web app is found through search, links and QR codes. A native app is found through the app stores, which only helps if people already search there for what you offer.

Every public page of a web app has its own URL that Google can index, that a customer can text to a friend, and that you can point an ad at. An app store listing is a single page inside a closed catalog. If people already look for your category in the store (ride hailing, food delivery, fitness tracking), a listing is a real channel. If they look for you by name after hearing about you elsewhere, the listing mostly serves people who already decided.

This is why local service businesses, professional firms, B2B software and content products tend to do better with a web app: the audience arrives from search and referrals, and the web gets them in without an install. See our AEO and AI search playbook for how web content is found by AI answer engines as well.

What does each one cost to build and maintain?

A web app is one codebase on one release path. A native app multiplies the work: two platforms (or a cross-platform framework), store compliance, and updates every time iOS or Android changes.

We do not publish a price for custom builds, because scope drives the number more than platform does. What we can say is where the cost differences come from. A web app deploys when you press the button. A native app deploys when a reviewer approves it, and every OS release can break something you have to re-test. Crash reporting, device testing, store screenshots and listing text are recurring work, not one-time work.

Budget the first year, not just the build. Include hosting, monitoring, store accounts, OS-update testing and fixes. For ranges and what drives them, read our web app development cost guide and the mobile app development cost guide. Custom web and mobile apps are quoted per project through our build studio, infinity.press.

What do the app stores charge and require?

Apple charges $99 per membership year, Google charges $25 once, and both review what you submit. Apple also takes a commission on digital goods sold inside iOS apps.

Per Apple's Developer Program page, membership is $99 per year, and the standard commission on digital goods and services is 30%, dropping to 15% for programs such as the App Store Small Business Program and for qualifying subscriptions. Different rules apply in some regions, including the EU. Google's Play Console help lists a US$25 one-time registration fee. Google also charges service fees on in-app sales, and the schedule differs by region, so check its current terms for your market.

The commission only applies to digital goods sold inside the app. A plumber collecting payment for a physical service, or a B2B tool billing through its own invoicing, generally falls outside it. A paid content or subscription product does not, which is a real argument for selling on the web.

Review is the other cost. Apple's App Review Guidelines (4.2) say an app "should include features, content, and UI that elevate it beyond a repackaged website." A thin wrapper around your site risks rejection. Plan for review time on every release, including urgent fixes.

Is a progressive web app the middle path?

Often, yes. A PWA gives you a Home Screen icon, a full-screen experience, offline support and push, on one codebase and with no store review. Its weakest platform is iPhone.

Per web.dev's installation guide, Android and desktop browsers show install prompts, while on iOS "a browser prompt to install your PWA doesn't exist" and users must choose Add to Home Screen from the share menu. That manual step is the main reason install rates are lower on iPhone, and it is a UX problem you have to design around with clear on-screen instructions.

A PWA suits products that are used often enough to deserve a shortcut but do not need background location or deep hardware access: field checklists, customer portals, internal dashboards, membership sites. It is a poor fit when store presence is itself your growth channel, or when you need features that only exist natively.

When should you NOT build a mobile app?

Skip the native app when people use your product rarely, find it through search, or need nothing the browser cannot do. Skip it too if you cannot fund updates for years, because an unmaintained app hurts your brand more than having none.

The opposite case is real too. If your product needs background location, Bluetooth hardware, health data, or a daily habit that push notifications reinforce, go native without apology.

A simple framework for choosing

Run your product through five yes-or-no questions in this order. The first "yes" that applies tells you where to start.

The final check is habit. An app has to earn its Home Screen spot against dozens of others. If you cannot say why someone would open yours weekly, start on the web.
