In the mobile app vs web app decision, most businesses should start with a web app: one product that runs in any browser, on phones and computers, and can be installed on the home screen as a progressive web app (PWA). Build a native or cross-platform mobile app when your users open it every day, when it has to work offline for long stretches, or when it needs device features the browser can't reach, such as Bluetooth, NFC or background location. Many companies end up with both, sharing one backend.
This guide is for business owners and managers deciding what to build. It explains the four options in plain terms, where they really differ, which questions settle the choice and what fits common cases like a customer app or an app for field staff.
The four options in plain terms
Responsive web app
A web app is software that runs in the browser. "Responsive" means the same screens adjust to a phone, a tablet or a large monitor. Customer portals, booking systems, dashboards and most SaaS products are web apps. People reach them through a link, and there's nothing to install.
Progressive web app (PWA)
A PWA is a web app with a few extras that make it feel like an installed app. Users can add it to their home screen, it opens full screen with its own icon, it can keep working through short network drops and it can send push notifications. You still build and host one product, and every user gets the new version the moment you publish it.
Native iOS and Android apps
Native apps are written in each platform's own language and tools: Swift for iPhone and iPad, Kotlin for Android. They get the smoothest performance and full access to the phone's hardware and system features. The cost is two codebases, two sets of developers' time and two store listings to keep up to date.
Cross-platform apps (React Native or Flutter)
React Native (from Meta) and Flutter (from Google) let one team write one codebase that becomes real iOS and Android apps, installed from the App Store and Google Play. For most business apps, users can't tell the difference from native. You may still need some native code for unusual hardware or very heavy graphics, and the app still goes through store review.
Where web apps and mobile apps really differ
The main differences at a glance. Most business apps don't need every column on the right.
Device features
Browsers can use the camera, GPS location, microphone, file uploads and payments through Apple Pay or Google Pay. That covers a lot of business apps. What they can't do well is background work: tracking location while the app is closed, talking to Bluetooth devices or reading NFC tags on iPhone, and deeper links into the phone's contacts, health data or widgets. If your app depends on one of these, a mobile app is the safer choice.
Offline use
A well-built PWA can store pages and data on the device, so a user can keep reading and filling in forms through a short drop in signal and send them when the connection comes back. For staff who work for hours in warehouses, basements, farms or remote sites, a mobile app gives you more control over large amounts of stored data and over syncing it without losing anything.
Push notifications
Android has supported web push notifications for years. Apple added them for iPhone and iPad in iOS 16.4 (2023), with one condition that matters for your plans: the user has to add the web app to the home screen first and then allow notifications by tapping a button inside it. A web page open in Safari can't send them. Since iOS 26, any site added to the home screen opens as a web app by default, which makes installing easier, but you still have to guide people through that step. If notifications are central to your business, such as order updates or appointment reminders, a mobile app reaches more of your users without that extra step.
App stores, review and fees
To publish on the App Store you need an Apple Developer Program membership (99 USD a year) and to pass Apple's review for every release. Apple says most submissions are reviewed within 24 to 48 hours, but a rejection means changes and another round. Google Play charges a one-time 25 USD registration fee and also reviews apps. If you sell digital content or subscriptions inside the app, both stores take a commission on those sales, the rate depending on the program and the country. Physical goods and real-world services, such as a delivery or a booking, are paid through your own payment gateway. A web app has no store, no review and no commission.
Updates
You update a web app once, on your server, and everyone has the new version on their next visit. A mobile app update goes through the stores, and some users stay on old versions for months, so your backend has to keep supporting them. Small content and settings changes can be designed to load from the server, which helps.
Being found
A web app's public pages can rank on Google and be shared by link in WhatsApp, email or social media. A mobile app is found in the stores, where you compete for search and reviews, and every new user has to download it before seeing anything. On the other hand, an icon on someone's phone is a daily reminder that you exist, which matters for apps people use often.
Cost and time to launch
We won't put a price on an app without seeing the scope, because the same idea can be a few screens or a large platform. What drives the cost is the same for every option:
- Number of platforms: one web app, one cross-platform codebase or two native apps.
- Screens and user roles: a customer, a driver and an admin are three different experiences.
- Integrations: your ERP, payments, maps, SMS and anything else the app talks to.
- Offline sync and device features: these add real work on both the app and the server.
- Security and data rules: logins, permissions, personal or financial data.
- Maintenance: new iOS and Android versions every year, store rule changes, bug fixes and server costs.
As a rule, one web app is the quickest to launch and the cheapest to run. A cross-platform app adds store setup, device testing and review time. Two native apps cost the most to build and to maintain, because every feature is built twice.
Five questions that decide it
- How often will people use it? Daily use, like a loyalty app or a staff tool, justifies an app icon. A form people fill in twice a year belongs on the web.
- Does it need hardware the browser can't reach? Bluetooth printers or scanners, NFC, background location or a heavy camera workflow point to a mobile app.
- Where will it be used? Long hours with no signal call for a mobile app with solid offline sync. An office or a shop with Wi-Fi doesn't.
- How will people find it? If new customers arrive from Google, ads or shared links, start on the web. If they're existing customers you can invite, a store app works.
- How will it make money? If you sell subscriptions or digital content, plan for store commissions or sell on the web. If you sell physical products or services, the stores don't take a share.
What fits common business cases
A customer app for a shop, restaurant or service
Start with a fast web shop or booking site, then make it a PWA so regular customers can install it. Add a mobile app when you have enough repeat customers to make loyalty points, order tracking and reminders worth the store effort.
An app for field staff
Sales reps, drivers and technicians often need offline use, GPS, photos and barcode scanning, and sometimes a Bluetooth printer. A cross-platform mobile app is a good fit, connected to your ERP so orders, stock and visits flow back to the office. Because you hand out the devices or the logins, store discoverability doesn't matter.
An internal tool or dashboard
Approvals, reports, HR requests and admin screens are almost always better as a web app. Staff use them from a laptop or a phone browser, and IT doesn't have to manage app installs.
A marketplace or platform
Marketplaces need to be found, so the public side starts on the web, where search engines and shared links bring traffic. The people who use it every day, such as sellers, drivers or service providers, often get a mobile app once the platform proves itself.
Need the app to work with your Odoo?
A mobile or web app can read and write your Odoo data through Odoo's API, so orders, customers, stock and visits stay in one system. NavyBits builds apps connected to Odoo for customers and field teams. Our article on mobile apps that work with Odoo explains the options.
Start with a web app, add a mobile app later
For many projects the best plan is to launch on the web, learn from real users and build the mobile app when the numbers justify it. The key is to design for it from the first day: one backend and one API that serve both, so the mobile app is a new front end on a system that already works, and you don't rebuild your business logic twice.
One backend from the start lets the mobile app reuse everything the web app already does.
Two warnings before you start. First, a mobile app that only wraps your website in a shell rarely helps: Apple's guidelines reject apps that offer little beyond a website, and users notice. Second, AI tools now make it easy to produce an app in days. That's a good way to test an idea, as we explain in our vibe coding guide, but code that works in a demo can still leak data or break under real use. Our article on the security risks of AI-generated code lists what to check before you publish.
FAQ
Is a PWA as good as a native app?
For many business apps, yes. A PWA can be installed, work through short network drops and send notifications. It falls short when you need background location, Bluetooth, NFC on iPhone, long offline sessions or the visibility of a store listing. In those cases a native or cross-platform app is the better choice.
Do PWAs work on iPhone?
Yes. Users can add a PWA to the home screen from Safari and other browsers, and since iOS 16.4 an installed web app can send push notifications after the user allows them. Notifications don't work for a site that's only open in a browser tab, so you need to guide users to install it.
Should I choose native or cross-platform?
Most business apps are well served by React Native or Flutter: one codebase, two stores and lower maintenance. Native is worth the extra cost for apps with heavy graphics, very demanding performance or deep use of the latest platform features.
Can I put a web app in the App Store or Google Play?
On Android, a PWA can be published to Google Play with Google's own tools. Apple is stricter and rejects apps that are little more than a website, so an iPhone app needs real app features to pass review.
How much does it cost to build a mobile app?
It depends on the number of platforms, screens and user roles, integrations, offline needs and security, plus yearly maintenance. A clear written scope is the only way to get a reliable figure, which is why we quote each project for its scope after an assessment.
