Website to app converter or your own app? How to choose

Your shop or service already works online. Customers have accounts, they order, and some come back every week. Now you have two very different offers on the table: an app builder that turns your website into an app in days, and a software house that builds an app for you.

Both can be the right call, because they solve different problems. In short: a converter is enough when the app only has to show your website. You need your own app when it has to work with your stock, POS or customer accounts.

What does a website to app converter actually do?

A converter, also sold as an app builder, shows your existing website or shop inside an app shell. You get an icon in the App Store and Google Play, a few native extras such as a tab bar and push notifications, and the content updates when your website does.

You pay a subscription. The builders we checked list plans from tens to a few hundred dollars a month, and the fee runs for as long as the app is live.

Inside, it is still your website. That is its strength, and its limit.

When is a converter enough?

More often than software houses like to admit. A converter makes sense when:

• Your customers buy once or rarely, and the website already works well on a phone.
• You want to see if anyone installs an app at all, before you pay for a build.
• Your shop platform already does everything you need, and the app only has to show it.
• Your budget is a few hundred a month, not a project.

If that is you, start there. Watch how many customers install the app and how often they open it. Those numbers will tell you more than any report.

When do you need your own app?

The picture changes when the app has to do something your website cannot. Typical signs:

• Loyalty is the point. Points, rewards and personal offers that customers check on the spot, at a counter or a checkout.
• Your data lives beyond the shop. Stock, POS or CRM systems the app must read and update.
• Push should be personal. A message about what one customer buys, not one blast for everyone.
• The phone does real work. Camera, scanning, location, use with a weak signal.
• You want to own it. The code, the store accounts and the roadmap, with no monthly fee to keep the app alive.

If two or more of these fit, a wrapped website will hold you back.

Will Apple accept an app made from a website?

Sometimes, and that is the risk. Apple's App Review Guidelines say an app should include "features, content, and UI that elevate it beyond a repackaged website." An app that only mirrors your shop can be rejected under that rule. More in why Apple rejects apps, guideline by guideline.

A second rule says apps made from a commercial template or app generation service are rejected unless the provider of the app's content submits them. In practice, the app goes out from your own developer account. Good builders know this. Ask before you sign.

What can your own app do? A real example

Pieprzyk runs a network of fuel stations with its own stock and POS systems, but it had no app. The value of a loyalty app there sits in the systems at the stations, not on a website.

We built a loyalty app, a management panel and a backend linked to their stock and POS. Customers see prizes and promotions based on where they are, collect points and swap them for rewards. The team runs prizes and promotions from the panel.

The app has been live at their stations since 2023, and we still improve it together.

Can the app use my existing backend and customer accounts?

Yes. Your own app does not mean a second system to run. We connect it to your existing backend through an API, so customers sign in with the account they already use on your website. If there is no API yet, we build a thin one on top of what you have.

Your data stays where it is. If you have your own developers, they keep the backend and we build the app against it. You own the code, the cloud account and the store accounts.

The store accounts cost little: Apple charges 99 USD a year, Google Play a one-time 25 USD. A company account at Apple needs a D-U-N-S number, so request it early.

How does it go, and what does it cost?

• Weeks 1-2Prototype to Plan: key screens and a fixed price per milestone
• Weeks 3-10Build on your systems, a new build on your phone every week
• Weeks 11-12Tests, store listing and launch in both stores
• After launch6-month guarantee

Prototype to Plan costs $5k, takes 1-2 weeks and is credited in full to the build. The build starts from $15k, typically $15-50k. It includes the links to your systems and an admin panel with MCP, so you can ask Claude or ChatGPT about your data. What moves the price up or down is in how much it costs to build an app in 2026.

You pay a fixed price per milestone and get an invoice per accepted milestone. You can stop after any milestone.

We build with AI because it makes us faster, and AI tests every build. Codigee experts review every line before it ships.
