How Apps and the Web Differ — Native, Web Apps, and App Store Review

The same service exists both as an app you install on your phone and as a website that opens when you type an address. The two look similar, but they’re built differently and reach users by different paths. That’s why questions like “should this ship as an app, or is the web enough?” and “why does an app take days to review?” come up so often.

In this post, I’ll unpack, without any code, how native apps and the web differ, what the hybrid app in between is, and why apps go through review.

The web opens by address, an app is installed and used #

The biggest difference is how it reaches users. The web opens immediately when you type an address in a browser. No install is needed, and when you push a change, the next person to visit sees the new version immediately. I covered how a website is made of a front-end, back-end, and database in IT Literacy for Non-Developers #1, and a web service runs on exactly this structure.

An app is different. You download it from the App Store or Play Store and install it on your phone to use it. Once installed, some features work even when the internet briefly drops, and it can tap more deeply into device-specific features like the camera or push notifications. In exchange, to ship a new version the user has to take an update, and before that it has to go through the store’s review.

A native app is built for a specific platform #

Among apps, one built for each platform with that platform’s own tools is called a native app. An iPhone app is built the way Apple prescribes, and an Android app the way Google prescribes, each made separately.

A native app’s strength is performance and polish. It runs the way the platform is designed for and has the deepest access to device features. In exchange, shipping the same app on both platforms means building each side separately, which takes proportionally more effort. The background of why mobile development roles split into iOS and Android is covered in What Do Developers Actually Do.

A hybrid app sits between the two #

To ease the burden of building a native app twice, there’s a middle approach, commonly called a hybrid app. You build the screens once with web technology, then wrap them in an app shell and put them on both stores.

This way you can write most of the code once and ship to both platforms at the same time, reducing cost. The term web app also comes up often, covering a wide range — from a form that runs in the browser with no install, to one wrapped in an app shell like this. That said, when you need to reach very deeply into device-specific features or need top-tier performance, a native app is still better, so the choice splits depending on what you’re building. “Whether to ship as an app or the web” is, in the end, a matter of weighing these trade-offs.

Why does app store review take time? #

The web reflects a change the moment you push it, but an app goes through review every time you submit a new version to the store. Apple and Google check the app’s content and behavior and pass it before it’s released to users.

Review is the process of confirming there are no security issues, that the app complies with platform policies, and that it behaves as described. So even an urgent fix is hard to ship right away, and it can take several days. This is the answer to “why can’t you fix the app right now?” Unlike the web, submitting isn’t the end — it has to clear one more gate called the store. Designing part of an app to load content from the web — so urgent changes can go live without a full app update — is also a response to this constraint.

Why this makes work easier for non-developers #

• You weigh app versus web together. Depending on whether install and device features matter, or fast access and instant updates matter, you can decide the direction together.
• You develop a sense of app timelines. Knowing that an app has a review gate and doesn’t reflect instantly like the web, you can set release and fix schedules realistically.
• You understand the limits of urgent fixes. You can see that not fixing an urgent app bug right away isn’t laziness but the review structure.

Wrapping up #

Today we looked at how apps and the web differ. The web opens right away by address and reflects changes instantly; a native app is built per platform with excellent performance and device access, but each platform must be built separately. A hybrid app is the middle-ground compromise that reduces cost, and app store review is why an app can’t reflect changes instantly the way the web can. The right answer depends on what you’re building.
