How to filter mobile app development companies by shipped apps, store experience, ownership, and post-launch support — before you sign.
By GGP Editorial
Choosing a company to build your app is different from choosing one to build a website or an internal tool. An app has to pass an app store review, keep working through operating system updates, and feel good enough that people keep it on their phone. The bar is higher, and the wrong partner shows up in bad reviews, not in a late internal report.
This guide is about how to filter the options down to a company that can actually ship, not one that talks well on a sales call.
Three things separate an app from other software work.
The stores. Apple and Google both review what you submit, and both can reject or delay a launch. A company that has never pushed an app through review will cost you weeks learning what they already should know.
The devices. Your app has to work across screen sizes, old and new operating systems, and different network conditions. That's a QA discipline of its own, and it's where cheap teams cut corners.
The updates. An app is never finished. Operating systems change, devices change, and users expect fixes. The company that builds your app should be the one you can call six months later when iOS ships a breaking change.
You can't evaluate a company against a vague idea. Before the first call, write down what the app does, who uses it, and the three to five things it must do at launch. This doesn't have to be a formal document. A page of notes is enough.
That scope is your measuring stick. When a company quotes a number, ask what that number covers against your list. When they describe their process, ask how they'd approach your specific screens. A company that can't talk about your app in concrete terms is just reciting a pitch. If you're not sure how much to put in the first version, our MVP development article explains how to scope a launch that's small enough to ship.
Anyone can show you nice designs. Ask for apps that are live in the App Store and Google Play, not screenshots.
Then use them. Download two or three of their apps and look at the details: how fast the screens load, whether the navigation makes sense, how it handles a flaky connection. Check the app's update history and its reviews. An app that was last updated two years ago tells you something about how the company handles maintenance.
Ask which parts they built. A company that only did the frontend screens for a project is not the same as one that built the app and the backend it talks to. You want to know who owns the full stack.
A few questions cut through the pitch quickly.
Who owns the code and the developer accounts? The Apple and Google developer accounts should be yours, not the vendor's, so you're not held hostage later. The source code should be yours under the contract.
Native or cross-platform, and why? For most business apps a cross-platform framework like Flutter or React Native saves real money and time by building once for both stores. Native makes sense for very specific needs like heavy graphics or deep hardware access. A good partner explains the trade-off instead of defaulting to whatever they happen to know.
How do you handle app store review? They should be able to tell you how they prepare a submission and what they do when Apple rejects it. If they look confused by the question, keep looking.
What happens after launch? Ask specifically about post-launch support, OS updates, crash monitoring, and how they handle a bug found by users. The launch is the start of the relationship, not the end.
Who builds the backend? Most apps need a backend for accounts, data, and payments. If the company only does the app and outsources the backend, you have two vendors to manage instead of one. We've written about what that backend work actually involves in our mobile app development cost guide.
A company that can ship an app has more than coders. Look for a group that includes a project manager who runs your calls, a designer who owns the user experience, mobile engineers for the app itself, backend engineers for the server, and a QA person who tests on real devices. This is the same shape you'd assemble in-house.
You can usually hear it in the first call. A real team asks about your users and your edge cases. A sales-only shop asks about your budget and timeline and little else. We covered how to read these signals in our guide on selecting a software development company, and the same logic applies to app work.
A few signals should end the conversation early.
No shipped apps in the stores. A portfolio of landing pages is not a portfolio of apps.
No working apps to try. If every "app" they show is a video or a PDF, they haven't shipped.
Vague answers on ownership. If they won't clearly say you own the code and the store accounts, that's a dealbreaker.
A quote before a scope. A real company asks about your product, users, and features before quoting a number. A quote in the first ten minutes means they're guessing.
No plan for after launch. An app that ships and is never touched again will break. A company without a maintenance story is selling you a launch, not a product.
App pricing varies a lot, and cheap is usually expensive. A too-low quote means someone is cutting corners — on QA, on the backend, on design — and you'll pay for it in rework and bad reviews later.
That doesn't mean you should pay the highest number either. The point is to understand what the price buys. Our mobile app development cost article walks through the drivers so you can read a quote instead of just comparing totals. Our timeline article covers the schedule side of the same question.
Where the team sits changes the price and the working rhythm, not the quality. A good offshore team with strong English and overlap hours can deliver the same app as a local one for less money. The risk is in communication and time zones, and it's manageable if you set it up right. Our nearshore vs offshore article covers the trade-off in detail.
GlobeSoft runs a Shenzhen-based team that schedules overlap hours with clients in the US, Europe, and Brazil, so the handoff happens live rather than over a twelve-hour gap. If you're weighing an offshore option, the thing to verify is not the country but the overlap: can you talk to them during your working day. If hiring itself is the sticking point, our checklist for hiring developers helps you ask the right questions of any candidate or vendor.
The best way to test a company before committing to a full build is a short, paid pilot. Give them a small, fixed-scope piece of the app — one or two screens with the core flow — and watch how they work.
You learn more in two weeks of a paid trial than in a month of sales calls. How do they ask questions? Do they flag problems early or hide them? Do they deliver what they said, when they said? A company that's sloppy on a two-week trial will be sloppy on a six-month build.
We built Africa Life, a lifestyle app that launched on the App Store. It started as a focused set of core services and grew from there, which is the pattern we recommend for most apps: ship the core, learn what users actually do, then expand. You can see how it came together in the case study.
How do I know a company has real app experience?
Ask for live apps in the App Store and Google Play, then download and use them. Check update history and reviews. A real app partner has a trail you can inspect.
Should I choose native or cross-platform?
For most business apps, cross-platform (Flutter or React Native) is the better choice because it builds once for both stores. Native is worth it for specialized needs like heavy graphics or deep hardware access.
Who should own the app store accounts?
You should. Own the Apple and Google developer accounts yourself, and make sure the contract says you own the source code.
Is a cheaper offshore team a risk?
Not automatically. The risk is communication and time zones, not location. Verify English level, overlap hours, and their shipped apps, and an offshore team can be a strong choice.
How much should a mobile app cost?
It depends on scope, backend, and integrations, but a typical business app runs tens of thousands of dollars. Our cost guide breaks down the range and its drivers.
What's the fastest way to evaluate a company?
A short paid pilot on a small fixed scope. It reveals how the team actually works, which is more useful than any sales call.
