How to Create Your Own App: 4 Routes and When Each One Makes Sense

You can create your own app today in four ways: yourself with a no-code tool, yourself with the help of AI, with a freelancer, or with an agency. The first two are cheap and fast, but they stop where payments, user accounts and years of looking after the app begin. The other two cost more, but you get a solution that can carry real customers. And at the start you don't need to know whether you need a website or a phone app.

This article is for studio owners, restaurateurs, service businesses, tutors and anyone with an idea along the lines of "if only my clients had this on their phone". We walk through all four routes: what they cost, what they can do and where you hit the ceiling.

Start with "who is it for and what should it solve?"

Most people start by asking "website or app?". That's the wrong first question. Before you decide what to build, be clear about why. Three sentences are enough:

Who will use it? Your customers, staff out in the field, or just you?
What problem does it solve for them? For example: clients stop phoning to book, technicians stop writing reports at home in the evening, regulars stop losing their loyalty stamps.
How do you solve it today? Spreadsheets, phone calls, WhatsApp, paper. That's your real competitor.

Once you have these answers, choosing a route gets much easier. And you'll often find that an off-the-shelf service for a few pounds or euros a month is enough. If you're looking for inspiration, browse our solutions by industry.

Route 1: No-code tools

No-code tools work like building blocks. You assemble the app from ready-made pieces such as lists, forms, buttons and a data table.

What it costs: you can start for free, but publishing almost always costs extra. Glide, for example, has paid plans from $25 a month, and you can't publish an app on the free plan. Adalo lets you build and test for free, but publishing to the App Store and Google Play starts with the Starter plan at $36 a month billed annually. Prices are from their price lists as of September 2026.

On top of that, if you want to be in the app stores, you pay Apple and Google too. The Apple Developer Program costs $99 a year, a Google Play developer account $25 one-off.

What it can do: internal tools, simple catalogues, forms, overviews built on a spreadsheet. For keeping records in your business or a simple list for clients, that's often enough.

Where it stops: at more complex logic, subscription payments, larger numbers of users, and a look that feels like your own brand. The app is also tied to the tool. If the tool raises prices or shuts down, there's nowhere to move it.

Route 2: AI tools

The newest option. You describe what you want in plain words to a tool like Lovable, Bolt or Replit, and within minutes it generates a working app. Then you refine it in conversation: "add a booking form", "make the colours green".

What it costs: you can start for free with a limited number of messages or credits. Paid plans start at roughly $20 to $25 a month (Lovable Pro $25, Bolt Pro $25, Replit Core $20, as of September 2026). On a larger app, credits run out quickly.

What it can do: a prototype you can show customers, a simple web app, an idea you can put in front of an investor. For testing an idea it's an excellent tool.

Where it stops: at payments, user accounts, personal data protection and security. And at publishing in the App Store and Google Play, which still requires your own developer accounts and several extra steps. We cover this in detail in building an app with AI.

Route 3: A freelancer

You find one developer to build the app for you, through a recommendation, LinkedIn or a freelance marketplace.

What it costs: rates vary so much between freelancers that a general figure is meaningless. But expect to pay for time. The less clear the brief, the more hours.

What it can do: a good freelancer builds a solid app, often for less than an agency. It suits a clearly defined job where you know exactly what you want.

Where it stops: one person rarely covers everything at once: screen design, development, testing, app store publishing and maintenance. The biggest risk is depending on a single person. If they fall ill, take a full-time job or stop replying, you're left with a half-built app. Before you start, agree where the code will live and who will have access to it.

Route 4: An agency

A team that covers the whole journey: from understanding the problem, through design and development, to publishing and care after launch.

What it costs: the most of the four routes. You'll find indicative prices by project type in how much a mobile app costs.

What it can do: payments, subscriptions, user accounts, connecting to the systems you already use, apps in the stores and looking after it all for years. A good agency will also tell you what not to build.

Where it stops: at small ideas that haven't been validated yet. If you don't know whether customers want it, start cheaper.

At Grow-App we work in two-week cycles, and before development we always do a solution design (Pitch Design). You see how the app will look and work before you spend money on development. With the restaurant reservation system, for example, the idea was first tested directly with restaurants, and not a single line of code has been written yet. The business plan comes after that.

Comparison: the 4 routes side by side

Route	What it costs	What it can do	Where it stops
No-code tool	Free to try, publishing from tens of $ a month	Records, catalogues, forms	Payments, complex logic, your own look, tool lock-in
AI tool	Free to try, paid plans from about $20 a month	Prototype, simple web app	Payments, accounts, personal data, security, app stores
Freelancer	By the hour, varies widely	A clearly defined app	Depending on one person, design and maintenance
Agency	Highest upfront investment	Complete solution incl. app stores and maintenance	Unvalidated small ideas

There's no single right route. Many successful apps went through several: the idea was tested with an AI prototype, then came a design, and finally the real app.

Website or phone app? You don't need to know

Customers mostly don't notice whether they're using a website that behaves like an app or an app downloaded from a store. The difference is in the details: notifications, working offline, an icon on the home screen, camera access, store fees on payments.

You don't have to decide this at the start. A common path is a website that works on phones and computers, with a store app added later. If you're curious about the differences, read our web vs. app comparison.

When does a custom solution pay off? A quick test

A custom app from a freelancer or an agency makes sense if you can answer yes to at least three of these:

You know exactly who it's for and what problem it solves.
The problem costs money or time today: missed bookings, hours of paperwork, customers drifting away.
You've tried off-the-shelf services and they fall short on something important.
The solution needs to take payments or manage customer accounts.
You want to use it for years, not for a month.
You want it to carry your brand, not someone else's logo.

If you answered yes only once or twice, start with an off-the-shelf service, a no-code tool or an AI prototype. You won't lose anything.

How to start this week

Write five sentences about the problem. Who, what, how you handle it today, what it costs you, what would change.
Check whether someone already solves it. An off-the-shelf service for a few euros a month is often the best answer.
Sketch three screens on paper. The start screen, the main action (a booking, say) and the confirmation. It doesn't need to look good.
Show it to five customers. Ask whether they'd use it and what's missing. A simple AI prototype helps here too.
Only then choose a route. Once you know what customers want, it's clear whether a tool is enough or you need a custom app.

Frequently asked questions

Can I create my own app for free?

You can build and test one, yes. Both no-code and AI tools have free plans. But publishing, your own domain or an app in the stores almost always costs money. A completely free app works as an experiment, not as a long-term business.

How do I make an app for my phone?

The simplest option is a website that behaves like an app on a phone and can be added to the home screen. If you want to be in the App Store and Google Play, you need developer accounts with both Apple and Google, and an app that passes their review. New personal Google Play accounts must also test the app with at least 12 testers for 14 days before publishing.

How much does my own app cost?

Anywhere from nothing, if you build it yourself on a free plan, to tens of thousands of euros for a large custom solution. It depends on what the app needs to do. You'll find specific ranges in how much a mobile app costs.

Do I need a technical specification before approaching an agency?

No. Describing the problem in your own words is enough. We create the specification together during the solution design.

Not sure which route is yours? Start with the problem, not the technology. Browse our solutions by industry, such as a booking system, a loyalty app or a video subscription platform, and find the one closest to your situation. Or write us a few sentences about your idea. No technical brief needed.
