Website, web app or mobile app: which one does your business actually need?
Most people asking "web app or mobile app" are really asking a budget question in technical clothes. Here is the answer up front, then the detail.
A website gives people information: your services, your prices, how to reach you. A web app lets them do something that changes data, in a browser, with no install: log in, order, upload, track. A mobile app is installed from the App Store or Google Play and can reach the phone itself.
The one question that decides it: does your product need the phone, or just a screen and a login? If you need the camera running in the background, location while the app is closed, Bluetooth, or hours of offline use, you need a mobile app. Everything else starts as a web app.
Website vs web app vs mobile app: the three-way comparison
The third comparison is the one nobody writes about, so here are all three side by side.
| Website | Web app | Mobile app | |
|---|---|---|---|
| Where it lives | A URL | A URL | The App Store and Google Play |
| Install needed | No | No | Yes |
| What the visitor does | Reads | Works: logs in, submits, transacts | Works, plus uses the phone |
| Found in Google | Yes, every page | Yes, every public page | Mostly no. Store search only |
| Updates | Instant | Instant | New build, review, then users update |
| Offline | No | Partly, with a service worker | Yes, fully |
| Camera and GPS | No | Basic, with permission | Full, including background |
| Platform fee | None | None | USD 99/year Apple, USD 25 once Google |
| Store commission | None | None | 15% to 30% on in-app purchases |
Examples make it concrete. A restaurant's menu page is a website. The ordering screen where you pick items, pay and get a receipt is a web app. Talabat's driver app, which tracks location while the phone is in a pocket, has to be a mobile app.
What a mobile app can do that a web app cannot
This is a short list, and that is the point. It has shrunk every year.
- Background location. Delivery tracking, fleet management, geofenced check-ins. A browser stops giving you location the moment the tab is closed.
- Bluetooth and NFC. Payment terminals, hardware pairing, tap-to-scan.
- Face ID and Touch ID. A web app can use passkeys, which cover most login cases, but it cannot reach into the biometric APIs the way a native app does.
- Serious offline use. A web app can cache pages and queue a form. An app can hold a full local database and sync days later.
- Heavy graphics. Games, augmented reality, real-time 3D.
- Being in the store. Some buyers only trust a business that has an app listing. That is a marketing reason, not a technical one, but it is a real reason.
If none of those describe your product, the mobile app is buying you an icon on a home screen.
What a web app can do that a mobile app cannot
Founders rarely weigh this side, and it is where most of the value sits for a young business.
It can be found. Every page of a web app has a URL Google can index. Content inside a mobile app cannot be searched for on Google. If a customer types your service and your city, a web app can answer them. An app cannot.
It updates the second you deploy. Found a bug in checkout at 9pm? Fix it, deploy, done. In a mobile app you build, submit, wait for review, and then wait again for users to install the update. Some never do, so you end up supporting old versions for months.
It opens from a link. A WhatsApp message, an Instagram bio, a QR code on a table. One tap and the customer is in. An app asks them to visit a store, download 80MB, create an account, and come back. Most of them do not come back.
It has no gatekeeper. No one can reject your web app, change the rules on you, or take a cut of your revenue.
What each one actually costs you
We are not going to quote a number here, because scope decides price and any figure without scope is marketing. What we can do is show you the shape of the bill, so you can read a quote properly.
A web app costs you: design, frontend, backend, database, hosting. One codebase.
A mobile app costs you all of the above, plus:
- an Apple Developer Program membership at USD 99 a year, and a Google Play developer account at USD 25 once
- a second frontend, unless you build cross-platform with React Native or Flutter, in which case you write one app codebase but still run two release pipelines
- testing on real devices across two operating systems and a spread of screen sizes
- store listings: screenshots at multiple sizes, descriptions, privacy declarations, age ratings, for both stores
- an app review queue on every single release, forever
- 15% to 30% of anything sold inside the app
That is why a mobile app is always the more expensive of the two for the same feature set. It is the web app's work, plus the store's work, and the store's work never finishes.
If you want real Kuwait figures for a combined build, we published the bands we actually see in Can a Kuwait agency build both my website and mobile app together?.
The app store delay nobody mentions in the quote
Timelines slip in a place clients never expect: between "the app is finished" and "customers can download it".
Apple publishes its own number. On average, 90% of submissions are reviewed in less than 24 hours. That is fast, and it is per submission, which means it happens again on every update.
Google Play is where new businesses get caught. If you are publishing under a personal developer account created after 13 November 2023, Google requires a closed test with at least 12 testers, opted in continuously for 14 days, before you are even allowed to apply for production access. The application review after that "usually takes 7 days or less". Google also notes that for certain accounts, review can take up to seven days or longer.
So a finished Android app on a new personal account is roughly three weeks from being downloadable, and none of those weeks are development. Register a company developer account early and recruit your testers while the app is still being built. This is the single most common launch delay we see.
A web app has no equivalent step. You deploy, and it is live.
Offline, notifications and hardware: where the line really sits
These three come up in every scoping call, and the common answers are out of date.
Offline. A web app with a service worker (a small script that caches pages and files in the browser) works offline for the things you cached. A customer can open your ordering screen on a lift with no signal and browse. What it cannot do well is a long offline session with a lot of data written locally. That is native territory.
Push notifications. Web push works on iPhone, with one catch: it only works for a web app the user has added to their Home Screen through Safari's share menu. In a normal Safari tab, there is no push. Apple added this in iOS 16.4. On Android, Chrome asks for permission straight from the browser, no install needed. Worth knowing: Apple briefly announced it would remove Home Screen web apps in the EU under the Digital Markets Act, then reversed that decision on 1 March 2024. They still work everywhere.
Camera and location. A browser can take a photo and read a QR code with permission. What it cannot do is keep reading location once the user has closed the tab. If your product depends on tracking someone through their day, that is a mobile app, and there is no clever way around it.
What about a progressive web app?
A progressive web app is a web app with an installable icon, offline caching and push notifications. It sits between the two options and it removes most of the reasons founders think they need an app.
It suits e-commerce, booking, customer portals, dashboards, and anything content-led. It does not suit background tracking, Bluetooth hardware, or games.
We wrote the full case, including the iOS limits and the real numbers from Starbucks, Pinterest and Alibaba, in Progressive web apps: why they're making a comeback.
How to choose: four questions
Answer these in order and stop at the first yes.
- Does the product need the phone's hardware while it is closed? Background location, Bluetooth, NFC, continuous sensors. Yes means mobile app. Nothing else will do.
- Do your customers need to use it without a connection for long stretches? Field teams, warehouses, drivers between towers. Yes means mobile app.
- Do you need customers to find you in Google? Yes means a web app, at minimum, because app content does not appear in web search.
- Are you still testing whether people want this? Yes means a web app. Launch in days, change it hourly, and add the mobile app once the demand is proven.
If you answered no to the first two, build the web app. You can add the mobile app later on the same backend, which is the cheapest order to do it in. Building the app first and bolting a website on afterwards is the expensive order, and we see it every year.
Building this in Kuwait
Two things change the calculation here.
Smartphone use in Kuwait and the wider GCC is high, and customers expect fast Arabic and English on the same product. That is an argument for a web app first, because bilingual routing and right-to-left layout are cheaper to get right once in a browser than twice across two native apps.
The second is the store account. Publishing under a Kuwaiti company entity, with the right bank and tax details registered, takes longer than founders plan for. Start it the week the project kicks off, not the week the build finishes.
What to do next
Write down the one thing your customer needs to do, in a single sentence. If that sentence contains a phone feature, you need a mobile app. If it does not, you need a web app, and the app can wait until you have customers to build it for.
