In short
If you are thinking about building a mobile app, first decide whether you really need a native app downloaded from the App Store. Most businesses are well served by a web app: it runs in the browser on phones, tablets and desktops, there is nothing to install, and it is faster and cheaper to build.
You need a native app if you use deeper phone features (for example Bluetooth devices or background location), or if being in the App Store is itself an important channel.
What is the difference?
Native mobile app. Built separately for iOS and Android and downloaded from the App Store or Google Play. It can use every phone feature, but there are two platforms to build, and every update goes through store review.
Web app. Runs in the browser, with one codebase on every device. Nothing to install, available from a link, and updates reach everyone immediately. Users can add it to their home screen as an icon, so day to day it feels very close to an app.
PWA (progressive web app). A web app that can be “installed” from the browser and supports some extra features, such as notifications or limited offline use. A good middle ground, but with less access to phone features than a native app.
Hybrid app. One codebase published to both stores. Cheaper than two native apps, but still means store releases, reviews and maintaining two platforms.
Comparison
| Web app | Native mobile app | |
|---|---|---|
| Installation | none, a link is enough | App Store or Google Play |
| Updates | instant for everyone | after store review, users must update |
| Devices | phone, tablet, desktop with one codebase | separate iOS and Android |
| Found on Google | yes, its public pages | no, only in the store |
| Phone features | camera, photo upload, location via the browser | everything, including background tasks |
| Build time | weeks | usually months |
| Cost | lower | usually several times a web app |
When is a web app enough?
For most apps built for businesses. For example:
- Client portal, where clients log in, upload documents, track orders or book appointments.
- Internal tool for your team: approvals, job sheets, reports, stock.
- Calculator or valuation tool for quote requests. Agrider's photo-based valuation tool and leasing calculator run in the browser, on phones too.
- SaaS product sold by subscription. DogDietLab is our own AI app: dog owners keep their dog's daily log on their phone, with nothing to download.
If your users arrive from a link, an email or Google anyway, a download step is more of an obstacle than a benefit.
When do you still need a native app?
- You need to connect to Bluetooth devices (scales, sensors, card readers).
- You need background location, for example in a courier app.
- The app must work fully offline for long periods.
- You need heavy camera or graphics features (AR, games).
- The App Store is the channel, because that is where your users look for you.
If none of these apply, start with a web app.
The safe route: start with a web app
This order works well on many projects:
- Build a web first version that works well on phones.
- Learn what users actually use and what is missing.
- If a native app really adds something (such as a device feature), build it for that proven need, not for an assumption.
That way you do not spend months and a large budget on an app before you know people will use it. More on this: MVP development: a working first version in weeks.
What we build
We build web apps that are designed for phones from the start, not squeezed down afterwards. If the first call shows you need a native App Store app, we tell you openly, including when a native development team is the better fit.

Frequently asked questions
Can a web app send notifications?
Email and SMS, yes, without any issue. Browser push notifications are possible too, but phones handle them in a more limited way than in a native app. If instant push notifications are business-critical, discuss it at the start.
Do the camera and photo upload work?
Yes. You can take and upload photos from the browser, which is how Agrider's valuation tool works.
Can it become a native app later?
Yes. The database and back-end logic stay, and a native app can use the same data. Only the interface needs to be rebuilt.
