To develop an app that will attract new customers and keep them stay, you have to be very selective when choosing a dedicated team of mobile app developers.

As someone working in an app development company, I’ve seen a multitude of unsuccessful projects. They come to us because they had the wrong choice with a bad development team before. Hence, to make your life easier, I’ve compiled a list of things you need to do before hiring mobile app developers.

Trust me; it’s as easy as counting 1, 2, 3.

Today’s guide is how to find trusted mobile app developers to help you maximize your business revenue.


Step 1 – Start searching for the best mobile app developers

Where to find your dream team?

Before considering different candidates, you need to know where to find them. There’s no reason your mobile app development team should live within the physical walls of your company. There are tons of companies hiring talent overseas, so should you as well. Here are your options:

  1. Search your social circle for people who have personally used the services of mobile app developers. Even if they can’t refer you to a trusted developer, they can be a good source of advice.
  2. Start your global research with a few high-quality mobile app development or technology blogs. Developers who constantly share their know-how can often explain complex issues easily and are masters of their craft. And here you are obviously now.
  3. Search independent company listings on platforms like Clutch, GoodFirms. Such platforms usually come in very handy for general information, including pricing, portfolio, and honest reviews. Note: If you search for “top mobile app developers” on Google, you will not get the same result. In most cases, all lists you see are paid ads under the article or research wrapper.
  4. You can also find mobile app developers on GitHub by looking at their code samples. Of course, you need relevant experience to get the right results.
  5. If your goal is to find developers for short-term collaboration (bug fixes, multi-feature implementation), search various autonomous communities and websites such as Upwork, Guru, or PeoplePerHour. These websites are homes for the self-employed. They usually show the experience of the developers, previous projects, all of their customers and their inquiries, and a performance rating. Has time tracking tools to ensure guaranteed payment.
  6. Many teams offer design in addition to programming, so finding a few communities for designers like Dribbble or Behance can lead to a handful of suitable candidates. Note: Most of the users of these communities are independent designers or design agents, so finding a full development team here could be a difficult task.

Who exactly are you looking for?


The most popular mobile platforms these days are Android and iOS. To develop native Android applications, programmers need to be Java experts. And iOS applications require Objective-C/Swift mastery. Another variation is to use cross-platform native development technologies like React Native.

[su_quote]The problem is, the coding itself is only part of building a successful application. [/su_quote]

The main goal of your product is to facilitate your business or even become your business, so finding a team that offers product management and business analysis services to analyze your idea, do marketing and competition research, and everything is essential to design.

Some tech experts may seem a little obvious at first, but they are necessary to complete your dream kit. Most mobile apps also require a robust backend, so your project will require at least one developer with experience in this area. A big advantage. Even if you don’t need a free web application/website right now, it may come up at some point.

Experienced developers can merge all of the existing and future solutions or implement various third-party API solutions.

It would be best if you also had a skilled QA engineer to fix any errors. Ask if the company adheres to the philosophy of test-driven development (an approach where testing, coding, and design are closely related, and unit tests are written before code). Know if they are writing automated tests and what devices they are using to test their applications.

And let’s not forget an excellent designer and project manager who holds the whole project together.

If you are looking for a long-term development partnership, I, therefore, recommend that you find a full-stack development company that can offer you the full range of development-related services.

Step 2 – Compare the mobile app developers 

Check out their portfolio

Check out the case studies in the developers’ public portfolio.

Find out whether they have developed apps in your industry or with a comparable range of functions. It’s not strictly necessary, but it is an obvious benefit to you.

Note: No development company displays all of the jobs it has carried out in its portfolio. If you are not looking for any projects, apply for other jobs directly by email.

>> InApps’ portfolio

Find out if their applications are economically successful.

Ask about the customer’s business problem and whether application development solved it. What are the advantages for companies by working with the developer? Did the startups get investments? How many downloads and active users do your applications have?

If the developers cannot provide you with this information, ask for the links to the relevant app stores or search on Google. Check out the app reviews. It would be best if you read the reviews as they may reveal some interesting and embarrassing details. Become a litmus test to understand if it’s worth reading on to see where to get it.


Download the apps and try them out to see how they work from the user’s perspective.

The first thing you will see is how quickly these applications startup. You can then measure the performance of the applications and the interactions between the various functions.

The first thing users notice about an app is the design, so take a closer look at the UX/UI of the apps. The ability of designers to create a visually pleasing user interface will be invaluable to any business.

Ask the developers to recount the development process and their thoughts about apps’ results before trying yourself.

You may find that some of the application errors can be explained by circumstances beyond the developers’ control.

Reach out to their past clients

Any credible company will be happy to provide you with a list of their past or current clients.

All you have to do is ask for contacts and communicate with their past clients. You can give them a call or find some common connections on LinkedIn or Facebook. Take the opportunity to find out how happy they are with the developers and ask if the contractors were on schedule and budget.

Find out if there were any emergencies during development and how well the developers handled them. Has the impending deadline redoubled your efforts or plunged you into the abyss of consternation? It is, of course, a good sign if the majority of the developer’s customers return with new projects or are recommended to them.

Make sure developers understand your business


Look for a developer interested in making an app that works and is passionate about the business side of the entire company.

Find out if the developer had customers in an industry similar to yours. Otherwise, a conversation about your target users and their understanding of this segment will show how suitable this developer is.

The money-related question to ask developers is how to monetize your app.

Standard practice is a small download/subscription fee. However, for some types of applications, this approach does not work at all.

This is where the candidate’s business expertise comes in. A developer familiar with your business domain can suggest an optimal solution—a way of monetization.

Matching expertise or not

Every developer specializes in developing a certain type of application. Once you have a good idea of ​​the features and functionality you want to have in your mobile app, you need to ensure your developer can turn your idea into a working product.

Good communication or not

Before your application is successfully published, there will be countless conversations to collect the requirements, define the scope of work, acquire adjustments and measure the project progress. Discuss how you will communicate during project development is essential.

Establish a schedule and define the means of communication in advance. Offshore developers offer you daily reports and voice calls. At the end of each week, a demo after each iteration.


At InApps, we have pursued the following approach: Before starting the project, we create and ratify a communication plan with our customer that identifies the most suitable form of communication for both sides, responsible for the various tasks and phases of the project. And how often we have to hold meetings. In this way, our customers have a clear idea of ​​what to expect from us and when to plan their work efficiently.

Ensure that the difference in time zones won’t impact your communications. For example, nobody likes to have important conversations at midnight. So check out if the developers in question have a history of successful cooperation with the clients in your time zone.

Consider some professional advice

Sometimes it is not enough to review each team member’s experience before signing a contract. It can also be quite difficult, or even impossible, to gauge the skills of programmers if you are not a specialist and you don’t have an experienced CTO on hand.

One trick is to find a friend, or at least someone you trust, who has the skills you need. You can then ask developers to post their code samples through GitHub or Bitbucket and ask your friend to check for quality and originality.

You can also find out if candidates actively participate in open source communities. That doesn’t speak only to their commitment to the development field, but it also shows that they are open to peer review.


Long-term cooperation

It would be best if you chose a developer worthy of a long and fruitful collaboration. If the candidate created a decent app but didn’t intend to take care of it in the long term, you can get rid of it without looking back.

Developing an app is not a one-off endeavor but a long road needing continuous improvement. So, find out if the developer offers support and maintenance services and the relevant terms and conditions.

Suitable budget

Last but not least, you need to consider your budget.

How much does the developer cost? How do you settle accounts with your customers? What are your payment terms?

The developer must be open and honest about their pricing and the engagement models they use. A developer will be happy to provide you with a free estimate but don’t expect a detailed estimate.

If you want to know why this is the case and what components are included in the price of your app, you can check out this article.

Be careful with the cost below average. Sometimes with lower-cost options, what you save may cost you more. Low cost leads to low quality in result.
