App Developers Guide

What you have decided is that you want an app developed. What you’ve yet to decide is who you should pay to do the job.

Our database contains hundreds of app development agencies, but you also need to know how to choose one. Brand names and awards are not enough as the app developer needs to be right for you, your business and your app idea. This brief guide helps you make a more informed choice.

Types of App Developer

There are four main types of app developers, though you can find many subsets within these (such as specialisation in a particular vertical or platform). Broadly, Enterprise-level companies tend to cost more but have the strongest and quickest means to develop your app, while boutiques are more like small artisans, and the final category is sole freelancers.

Enterprise (in house): Large companies that generally do everything from designing your app to building, testing and publishing it. They tend to require the largest budgets, and their designers and coders are mostly employees.

Enterprise (outsource): The main difference between these and the companies above is that these employ freelancers to work on your project. This allows for more flexibility – maybe you already have a User Interface, or have coding skills but would like something designed. It also drives costs down – app development through these companies is generally cheaper.

Boutiques: These studios can be as small as a two-person team. They take on fewer projects and deliver high levels of polish and also tend to be highly specialised in particular types of apps or industry verticals.

Freelancers: You may find one person willing to do everything (design, coding, testing, publishing) but truth be told, the people who can do all of this and do it well are few and very expensive. It’s not impossible to build an app with freelancers, but it does add a lot of work and uncertainty.


There are two major platforms – iOS (the iPhone’s operating system) and Android (Google’s system used on everything from Samsung to LG and Huawei phones).

As of Q3 2016, Android holds 86.8% of global market share, while iOS holds 12.5%.

There’s also Windows 10 Mobile, although that has less than 1% of market share in the US and in all other markets is under 10%.

App Developer Locations

As with most tech industries, major cities are the main hubs for app development. Some boutique studios can be found in smaller communities, but the general rule applies.


California is the number one hub for mobile app developers, with San Francisco and Silicon Valley being the main ones and Los Angeles not far behind. New York is probably the second biggest US city for app development, with some big name studios located there, followed by Chicago and Boston. You can also find out more in our guide on choosing a US App Developer.


London is the major hub here, with a very high concentration of app devs; the north also offers some excellent studios however, chiefly in Manchester and Newcastle. You can also find out more in our guide on choosing a UK App Developer.


India is a very large hub for app development and the majority of devs are concentrated in three cities: Bengaluru, Hyderabad and the New Delhi metropolitan area. You can also find out more in our guide on choosing an Indian App Developer.

Eastern Europe

Ukraine is the strongest contender for the “central hub” title of app developers in Eastern Europe but there are plenty throughout the region, with some of the best ones being in Poland, Bulgaria and Romania.

Pricing and Costs

The price of an app can vary massively depending on how complex the app is, on whether it’s just Android or iOS, if it’s native or hybrid and especially on the developer you choose.

Estimates range from as little as $3000 to $150,000 for more complex apps made by high-end developers.

Costs also change according to country. The median cost per hour for Android development in the US is $167, $70 in the UK and $30 in India. For iOS the media is $150/hour in the USA, $70/hour in the UK and $26/hour in India (Android is heavily favoured over iOS in India.)

Crew have a tool for estimating the cost of your app which you can find here.

If you’d like to know more about app development costs, you can also check our guides on how to choose an app developer in the US, UK and in India.

How to Select an App Developer

Checking out the app developer’s portfolio is always a good idea. Previous experience in your field or business sector might not only get you a better app, but a cheaper one too: the challenges tackled and resolved in making prior apps will reduce the development time for yours and it also helps if your chosen app developer knows the ins and outs of your specific industry.

Reviews and recommendations are also a valuable resource – if you know a business similar to yours, find out who made their app and whether it works and read the reviews for it in the app store.

You can also check out our marketplace for app developers, and read our in-depth guide on how to choose one.


App Developers FAQ

Our answers to the most frequently asked questions about finding, choosing and engaging with an app development company or agency.

How much does it cost to develop an app?

It depends on a wide variety of factors, from the type of app and it’s features and the developer you choose. The lowest price point hovers around $3000, while larger apps can cost as much as $250,000. Some estimates for an Uber-like app go up to $300,000. In this guide, we break down the cost of app development to show you where the money goes.

A good tool to estimate an approximate cost for your app idea can be found here.

How long does it take to make an app?

According to Kinvey, it can take 18 weeks to create an app, while our own estimates put it at 24 weeks. Once again this greatly depends on the type of app and your developer, but this range includes the majority of development times for medium-sized apps.

How can I find an app developer?

There are a large number of resources online. You can start by looking through Business of App’s directory.

Another strong online directory is found on

There are also dozens of app developer events around the world yearly, which you can find in our event directory.

If you’re looking specifically for freelancers then online platforms like Upwork, Freelancer and We Work Remotely.

Where can I find a developer partner for a startup app?

Meetup is a great tool for this, and developer meetings can often be found on the platform, as well as platform-specific ones for iOS and Android.

How many app developers are there?

A lot. In October 2016, the most recent estimates put the number of app developers at 12 million globally, of which around half develop for Android, and 2.8 million focus on iOS.

In 2014 , Asia held the highest number of app developers with 760,000 (32.9% of total app developers at the time), swiftly followed by Europe and North America with 29.7% and 29.4% of devs. Keep in mind however that since then around 800,000 new developers have entered the market per year.
