Choosing an app development company is less about finding the most impressive portfolio and more about finding a team that will make good product decisions with you. Plenty of companies can write code. Fewer will tell you which feature to cut, who owns the app after launch, or what happens when the first store review comes back with a rejection.
This guide covers what to look for, the questions worth asking, the warning signs, and the contract details that protect you.
Start with your own clarity
You will judge companies better if you know what you are asking for. Before you contact anyone, write down:
- The one job the first release must do, and for whom.
- The platforms you need at launch and why.
- The systems the app must connect to.
- Any real deadline, and what it depends on.
- A rough budget range.
If the job is still fuzzy, spend time on that first. Our guide on how to validate an app idea is a good place to start. A company that helps you sharpen the job is worth more than one that quotes your feature list as written.
What to look for in an app development company
They ask about the product, not only the features
Good partners ask who the users are, what they do today, and what would make them switch. They push back on scope that does not serve the first release. If the first conversation is only about screens and a price, the product thinking will be missing later too.
They can explain their technical choices
Ask why they would build native or cross-platform for your product. A strong answer refers to your app’s needs: device features, performance, the team who will maintain it. A weak answer is “we always use X”. Our notes on native vs cross-platform and Flutter vs React Native explain the trade-offs so you can judge the answer.
Design and engineering work together
Apps fail on journeys as often as on code. Look for a team that prototypes the critical paths and tests them before engineering commits. If design is outsourced or treated as decoration, expect rework.
Relevant work, explained honestly
Portfolios show what an app looks like, not how it was made. Ask to walk through a past project: the brief, what changed, what went wrong, and what they would do differently. Specific, candid answers are a better signal than polished screenshots. If you can, speak to a past client.
Quality assurance on real devices
Ask how they test: on which devices, which operating system versions, and who signs off. Testing only on simulators or a single phone misses the problems your users will find first.
A plan for after launch
Store submission is not the end of the project. Ask how they handle the first month of fixes, operating system updates, crash reporting, and ongoing maintenance. A company that disappears after launch leaves you with an app nobody can safely change.
Questions to ask before you sign
- Who will work on our app, and will that change during the project?
- Who makes product decisions day to day, and how do we approve them?
- How do you estimate, and what is excluded from this estimate?
- How often will we see working software?
- How do you handle a change in scope?
- How do you test, and on which devices?
- Who submits to the App Store and Google Play, and under whose account?
- What happens in the month after launch?
- What does ongoing maintenance look like, and what does it cost?
- If we part ways, how do we get everything we need to continue?
Warning signs
- A fixed price before any questions. A quote that arrives without discussion of users, integrations, and platforms is a guess.
- Yes to everything. A partner who never challenges scope will build whatever you ask, including the parts that should not exist.
- Vague answers about who does the work. If the team is unclear or heavily subcontracted, quality and communication suffer.
- No working software until the end. Long periods with only status reports hide problems until they are expensive.
- Guaranteed results. Nobody can promise downloads, rankings, or revenue for an app that does not exist yet.
- Unclear ownership. If they will not confirm that you own the code and accounts, walk away.
Contract details that protect you
- Intellectual property. The contract should state that you own the code, designs, and content created for you, on payment.
- Source code access. Code should live in a repository you own or can access at any time, not only on the agency’s machines.
- Accounts in your name. The Apple and Google developer accounts, cloud hosting, domain, analytics, and third-party services should belong to your business.
- Clear scope and change process. What is included, what is not, and how changes are priced.
- Acceptance criteria. How you decide a milestone is done.
- Warranty and support. How long defects are fixed at no cost after launch, and the terms for ongoing support.
- Handover. Documentation, credentials, and a walkthrough if the relationship ends.
Local, offshore, or a mix?
Location affects price, time zones, and how easily you can meet. It matters less than communication and process. A remote team with clear weekly demos, written decisions, and overlapping working hours can be easier to work with than a local team you rarely hear from. Ask how they handle time zones, which tools they use, and how quickly they respond.
Comparing proposals
Lay proposals side by side and compare the same things: scope, team, approach to design, testing, timeline, post-launch support, and ownership terms. The lowest number is often missing the backend, admin tools, or support after release. Our guide on how much it costs to build an app lists the parts that most often go missing from early quotes.
How Sovassa works
We start by naming the job, the users, and the smallest release that can teach you something. We will tell you if part of the brief should wait, and if a problem is not one we should take on, we say so before a proposal. Design, build, device testing, store release, and the first month of fixes sit in one plan, and you own the code and accounts from day one.

Frequently asked questions
Should I hire a freelancer or an agency?
A skilled freelancer can be a good fit for a small, well-defined app. An agency brings design, engineering, testing, and project management together, and is less exposed if one person becomes unavailable. Match the choice to the size and risk of the product.
How many companies should I talk to?
Three to five is usually enough to see the range of approaches without spending weeks on proposals. Give each the same brief so the answers are comparable.
Is the cheapest proposal a bad sign?
Not on its own, but check what it leaves out. Compare scope, testing, and post-launch support before comparing price.
Do I need a technical person on my side?
It helps, but it is not required. What you do need is one person who can make product decisions quickly and is available to review work regularly.
