Mobile app

Short answer: for most business apps, cross-platform development (Flutter, in our case) gives the best value for money, because a single codebase produces both the iOS and the Android app, with a 30 to 40 percent cost saving compared to two separate native apps. Purely native development is only worth it for apps with extreme graphics or hardware demands, and a web app wins where installation is more of a barrier than a benefit. Let’s go through the details.
Native app. Built separately for iOS (Swift) and Android (Kotlin) with each platform’s own tools. It’s the fastest, has the deepest hardware access, and is the most expensive route, because you’re effectively building and maintaining two apps.
Cross-platform app. One codebase that compiles into a real, installable app for both platforms. The two big frameworks are Flutter and React Native. To the user it’s indistinguishable from native, but the development and maintenance cost sits closer to one app than to two.
Hybrid app. Essentially a website wrapped in an installable shell (WebView). Cheap, but it shows: a clunkier experience, limited platform features. These days only a narrow set of cases make it the right choice.
Web app / PWA. Runs in the browser with no installation, and the PWA version can be added to the home screen and even works partly offline. No store, no download barrier; in return, there’s no full push notification support on iOS and no deep hardware access. We have a separate article on PWAs: the power of Progressive Web Apps.
| Criterion | Native | Cross-platform | Hybrid | Web / PWA |
|---|---|---|---|---|
| Development cost (2 platforms) | highest | 60 to 70% of native | low | lowest |
| Performance, experience | excellent | excellent for typical business apps | medium | good, but browser-dependent |
| Hardware access | full | almost full | limited | limited |
| Maintenance | two codebases | one codebase | one codebase | one codebase |
| Store presence | yes | yes | yes | not needed |
| When to choose it | games, extreme graphics, special hardware | most business apps | rarely worth it | rarely used, content-heavy interfaces |
Let’s take a mid-sized business app that costs 10 million HUF (about €25,000) built with cross-platform technology. The same app built as two separate native apps would cost roughly 16 to 18 million HUF, because the screens, the logic, and the tests all have to be built twice, and every change in maintenance has to be paid for twice as well. The web version, if the features allow it, can come in at 6 to 8 million HUF. You’ll find a detailed breakdown of mobile app prices here: how much a mobile app costs.
The numbers show why cross-platform is the default: for most business apps, no noticeable benefit offsets the extra cost of going native.
At ZNiTech we work with Flutter, and across the projects of the last few years we’ve never once hit a business requirement that cross-platform technology couldn’t handle. What we did run into: payment integrations, maps, camera-based barcode scanning, push campaigns. All of it ran from one codebase. In practice the dilemma usually isn’t native versus cross-platform, it’s whether you need an installable app at all, or whether a well-built web app is enough. That’s the question worth settling first, and our website or web application article helps with exactly that.
Flutter or React Native? Both are proven frameworks with large communities, and with a good team either one produces an excellent app. We chose Flutter for its predictable performance and its consistent handling of the UI. When you’re choosing, the development team’s experience carries more weight than the difference between the frameworks.
Will users notice the app isn’t native? For business apps, no. It shows up in the store the same way, installs the same way, and runs just as fast. The difference is in the economics of development, not in the user experience.
Can a PWA be enough instead of an app? If you don’t need store presence, iOS push, and deep hardware access, then yes, and you’ll save a significant amount. For online stores and content-heavy interfaces, this is often the best route.
What happens to the app when a new iOS or Android version comes out? The frameworks keep up with the platform updates, and it’s worth adjusting the app a few times a year. That’s part of normal maintenance, which we covered in our article on prices.
