Most businesses should start with a website. People can find it on Google, it opens on every phone without installing anything, and it costs less to build and run.
Build a mobile app only when three things are true:
- Customers use you every week.
- They need phone features like notifications or location.
- You have already proven people will pay.
This guide gives you a simple test by business type and the real costs of each option in Algeria. It also covers the middle option most people never hear about.
What is the difference between a website and an app?
A website is a set of pages anyone can open in a browser, by typing an address or tapping a Google result. A mobile app is a program people must find in a store, download and install on their phone.
Think of a shop on a busy street. Anyone walking past can look in the window. That is your website.
A loyalty card is different: only regular customers ask for one and keep it in their wallet. That is your app.
Both are useful. But a shop with no window and only loyalty cards will not get many new customers.
Which should you build first for your business?
Use this table. Find your business, and start with the first column.
| Your business | Start with | Add later | Why |
|---|---|---|---|
| Restaurant, café, salon, clinic | Website, Google Maps listing, WhatsApp button | App for loyalty or frequent bookings | New customers search and compare before they visit |
| Gym or club with daily bookings | Website with online booking | App once most members book every week | Members use it often, so an app earns its place later |
| B2B services, consulting, agency | Website | Rarely an app | Buyers research on Google before they call |
| Online store | Website | App when you have many repeat buyers | Google and social links bring new buyers to a website |
| Delivery, ride, or daily habit service | App | Website for information | The service lives on the phone: location, alerts, daily use |
| Training, courses, content | Website | App for learners who come back daily | Content needs to be found through search |
The pattern: a website brings new customers, an app keeps regular ones. Most new businesses need new customers first.
Why is a website usually the better first step in Algeria?
Because of how Algerians reach businesses online.
About 37.8 million people in Algeria used the internet in late 2025, 79.5% of the population. There were 55.6 million mobile connections (DataReportal, Digital 2026: Algeria). With more mobile connections than people, most of them will meet your business on a phone.
A website is one tap away from a Facebook post, an Instagram bio or a Google search. An app asks for a store visit, a download and free space on the phone first. Every extra step loses people.
And about 87% of phones in Algeria run Android (StatCounter, September 2026), often mid range models with limited storage. A website costs your customer no space at all.
How much does each option cost to run?
The build price is only the start. Here is what each option costs to keep alive.
| Cost | Website | Mobile app |
|---|---|---|
| Store fee | None | Google Play: 25 dollars once. Apple: 99 dollars per year |
| Platforms to maintain | One | Two (Android and iPhone), or one with Flutter |
| Updates | Live for everyone instantly | Each update goes through store review, and users must update |
| How people find it | Google search, links | Store search, or a link to the store |
Store fees: Google Play, 2026 and Apple, 2026.
Here is the Algerian catch. Both stores charge in dollars, by international card. A CIB or Edahabia card can't pay them.
I explain this payment wall in free AI vs paid AI, and it applies to app stores the same way.
Is there an option between a website and an app?
Yes. It is called a PWA, a Progressive Web App: a website built to behave like an app (web.dev).
A PWA opens in the browser like any site. But the visitor can add it to the home screen, where it opens full screen like an app. It can also keep working on a weak connection.
For many Algerian businesses this is the smart middle step. You get the app feeling for regulars, the Google visibility of a website, and no store fees.
What mistakes do business owners make when choosing?
- Building both on day one. You end up with two average products instead of one good one, and twice the bills.
- Copying a competitor's app. Your competitor may be making the wrong call. Or they have a different budget and different customers.
- Building an app nobody can find. An app with no website and no Google presence depends entirely on you sending people to the store.
- Forgetting the store fees and card problem. Plan how you will pay Apple and Google before you plan the app.
- Building a website that loads slowly on mobile. A slow site loses the advantage it was chosen for. I show the common causes in why your landing page is not converting.
When is it time to build both?
Add the second platform when all four of these are true:
- Your first platform is busy and working.
- Customers keep asking for the other one.
- You have the revenue to build and maintain a second product.
- Different customer groups clearly prefer different platforms.
When that day comes, build the app with one shared codebase for Android and iPhone. I use Flutter for mobile and Next.js for websites, the same stack behind the platforms I build. If you are wondering what an app costs, read the 50,000 DA app formula.
What should you do this week?
- Today: find your business in the table above and write down your first platform.
- This week: ask your last ten customers how they found you. Google, Instagram, a friend?
- If most found you by search or links: start with a website.
- If they already use you every day: an app or a PWA may be worth it.
- Before any build: check that your Google Maps listing and WhatsApp number are correct. They are free and they work today.
