Summary
There are four main ways to hire app developers: a freelancer, a studio or agency, your own in-house team, or developers added to a team you already run. In short:
- A freelancer is cheapest by the hour and suits small, clear jobs, but you manage the design, testing and deadlines yourself.
- A studio or agency brings design, building, testing and launch in one team. It’s usually the best fit for a new app or a first version.
- An in-house team gives you the most control and costs the most: a US software developer’s median salary is $135,980 a year, before benefits.
- Added developers (staff augmentation) suit companies that already have someone leading the technical work.
- Whoever you hire, try their live apps, meet the people who will build yours, start with a small paid piece of work and keep the code and accounts in your name.
What building an app actually takes
Before choosing who to hire, list what the work needs. Even a small app usually needs:
- Design: how the app works and how it looks, screen by screen.
- The app itself: for iPhone and Android, often from one codebase.
- A backend: the server and database behind the app, for accounts, data and payments.
- Testing: on real phones, before every release.
- Someone running the project: keeping scope, budget and deadlines on track.
- Launch and upkeep: getting through app store review, then updates and fixes.
One person rarely does all of that well. That’s the real choice when you hire: do you put the team together yourself, or hire one that already works together?
Your options compared
| Option | How you pay | Good for | Watch out for |
|---|---|---|---|
| Freelancer | By the hour, about $25–$150 depending on country | Small jobs with a clear scope, or extra hands for an existing team | You manage design, testing and deadlines; one person is a single point of failure |
| Studio | By the project, often $15,000–$120,000 for a first version | New apps and MVPs, especially without a technical co-founder | Fewer people free at once than a large agency |
| Large agency | By the project, usually at the highest rates | Big budgets with many parts built at once | Senior people in the sales meeting, juniors on the build |
| In-house team | Salaries: a median of $135,980 a year per US developer | Products already working, that need full-time care | Slow to hire, and costly before you know the product works |
| Added developers | A monthly fee per developer | Adding hands to a team you already lead | You still need someone to direct the work |
Hiring a freelancer
A good freelancer is fast and good value for a well-defined job: a feature in an existing app, a fix, or a small app where you already have the designs. Freelance marketplaces make it easy to find people, and add their own fee on top.
The catch is everything around the code. You’ll need to supply the design, test each release, keep the scope in check and find a replacement if your freelancer gets busy or moves on. For a whole new app, that usually means hiring several freelancers and managing them yourself.
Choose a freelancer if the job is small and clear, and you have the time and know-how to manage it.
Hiring a studio or agency
A studio or agency gives you a team that already works together: design, app, backend, testing and someone running the project. You agree on what to build and a budget, and they take it from idea to launch. For a new app or an MVP, that’s usually the quickest and least risky way to get to launch.
The difference between a studio and a large agency is mostly who does the work. At a small studio, the people who quote your project are the ones who build it. At a large agency there are more people to draw on, but your project may be handed to a team you never met in the sales meeting.
Choose a studio or agency if you’re building a new app, don’t have a technical team, or want one team responsible for the whole result.
Building an in-house team
Your own team gives you the most control and keeps knowledge inside the company. It’s also the most expensive way to start. The median salary for a software developer in the US was $135,980 in May 2025 (US Bureau of Labor Statistics). An app usually needs at least two developers, one for the app and one for the backend, so that’s about $272,000 a year in salaries alone, before a designer, benefits, recruiting and equipment.
Hiring also takes time, and you need someone who can judge technical candidates. Many companies get the first version built by a studio, then hire in-house once the product has proven itself.
Build an in-house team if the app is your business, it already works, and it needs people on it full time for years.
Adding developers to your team
With staff augmentation (also called hiring dedicated developers), a company provides developers who join your team for a monthly fee. It’s a quick way to add hands without hiring, if you already have a technical lead who plans the work and reviews it.
Choose this if you have a product and a technical lead, and need more people to build faster.
How to vet app developers
Whichever option you choose, these checks catch most bad hires:
- Try their live apps. Ask for App Store and Google Play links, not screenshots, and use the apps on your phone.
- Meet the people who will build yours. Ask who will design it, who will write the code and how much of their time you’ll get.
- Talk to two past clients. Ask what went wrong and how the team handled it.
- Ask what they’d build first. A good team questions your feature list and suggests what to leave for later.
- Start with a small paid piece. A design sprint or one feature shows you how they work before you commit the whole budget.
- Check how they’ll keep you updated. Weekly demos and written updates beat long silences followed by a big reveal.
- Get ownership in writing. The contract should give you the rights to the code, and the code, app store accounts, domain and servers should be in your name from day one.
Red flags
- a quote far below everyone else’s, with no breakdown
- yes to every feature, with no questions
- no live work you can try
- no access to the code until the end
- the person selling the project won’t be anywhere near building it
Hiring developers in another country
Many companies hire app developers abroad to get more for their budget: hourly rates for experienced developers run from about $100–$200 in the US to $25–$60 in India (see our guide to app development cost for more). Done well, it can work as smoothly as hiring locally. Make it work with:
- a few hours each day when both sides are working, for calls and quick questions
- a demo every week or two, so you see real progress
- written updates and decisions you can refer back to
- your code and accounts in your name, so you’re never locked in

FAQs
How much does it cost to hire an app developer?
Freelancers charge about $25–$150 an hour, depending on country and experience. Studios and agencies usually price by project, often $15,000–$120,000 for a first version. An in-house developer in the US earns a median of $135,980 a year, before benefits.
Should I hire a freelancer or an agency?
A freelancer, for a small, clear job you can manage yourself. A studio or agency, for a new app built from scratch, since you need design, the app, a backend and testing working together.
Where can I find good app developers?
Referrals from founders who have launched an app are the most reliable. After that, look at review directories for studios and agencies, and freelance marketplaces for individual developers.
How do I know if an app developer is any good?
Try their live apps on your phone, talk to two past clients, and start with a small paid piece of work before committing the whole budget.
Is it safe to hire app developers from another country?
Yes, if you keep the code and app store accounts in your name from day one, see a demo every week or two, and agree on hours when both sides are working. Radical Labs works with clients remotely, wherever they are.
Who owns the code when I hire app developers?
You should. Get a contract that gives you the rights to the code, and keep the code, app store accounts, domain and servers in your own name.
Should I hire one developer or a team?
For a new app, a team. Most apps need design, the app itself, a backend and testing, and one person rarely does all of them well.
Can Radical Labs build my app?
Yes. Radical Labs is a small senior studio that designs and builds web apps, mobile apps and AI tools, and you work with the same people from the first call to launch. Send a short brief at radicallabs.io/contact.
