Freelancer, agency or studio: who should you hire to build your app?

You've got an app idea. Or half an app, built by someone who's since gone quiet. You Google "hire an app developer", click a couple of links, and twenty minutes later you're on a freelance marketplace, scrolling through profiles that all say "expert" and writing a job post.

We know, because we spend time on those marketplaces too. And the same four jobs come up again and again:

• "Audit my app" or "fix my vibe-coded MVP"
• "Looking for a fractional CTO"
• "Build a mobile app"
• "Build a web platform"

Every one of those is a fair thing to need. The question is who's best placed to do it, and the answer isn't always us.

When a freelancer is the right call

For a small, clearly defined job, a good freelancer is hard to beat. A bug fix, one feature, a landing page. You know what you want, you can check it's done, and the price makes sense.

It gets harder when the job is fuzzy. Hourly billing on a vague brief has no natural end. If you're not technical, it's tough to tell a great developer from a confident one until the code's already written. And it's one person. If they get busy, get ill or get a better offer, your project stops with them.

When an agency is the right call

If you've got a large budget, a complex build and you want account managers, project managers and a full team, an agency is built for exactly that.

What you're also paying for is the structure: the office, the layers, the margin on top. And the person who wins you on the sales call often isn't the person writing your code.

Where a small studio fits

A small studio sits between the two. Senior people, who actually do the work. A fixed price agreed before anything's built. The code lives in your repository, under your name, from day one. And someone's still around after launch, when iOS updates and something breaks.

We're not the cheapest option on that list, and we're not trying to be. We're trying to be the one you don't have to replace in six months.

Back to those four jobs

"Audit my app." Before you pay anyone by the hour to "just fix it", get someone to tell you what's actually wrong. Otherwise you're paying for them to find out. We do this as a flat £700 Tech & Product Audit: what's broken, what it'll cost to fix, and whether it's worth fixing at all. If your app was vibe coded, this is worth a read first.

"Fractional CTO." Sometimes that really is a part-time executive. More often it means "I need someone senior to make the calls." What to build first, which tech to use, who to hire, whether the quote in your inbox is fair. That's a few hours of good judgement, not a title on an org chart.

"Build a mobile app." A real app, listed in the App Store and Google Play, that you own, not a website wrapped to look like one. Ask how it'll be maintained, because phones update every year and apps nobody looks after quietly stop working.

"Build a web platform." Watch for anything that ties you to a platform you can't leave. We've written about no-code lock-in before. Short version: if you can't take the code with you, you're renting.

Five questions to ask whoever you hire

1. Who actually writes the code?
2. Is the price fixed, or is it hourly with no ceiling?
3. Where does the code live, and is it in my name?
4. What happens after launch?
5. What happens if you disappear?

A good freelancer, agency or studio will answer all five without flinching. If someone gets vague on number three, that's your answer.
