Our semi-annual Developer Economics survey is now LIVE! Don’t miss a chance to join over 40,000 developers from 160+ countries who take part in our surveys every year to tell us about trends and shape the future of where software development is going next.

We recently published brand new State of the Developer Nation report 14th edition, based on the insights from our Developer Economics survey which ran in Q4 2017 and reached over 21,700 developers in 169 countries. We reveal developers’ thoughts on which emerging tech will have the most impact in the next 5 years, the future of serverless platforms, the most promising AR/VR hardware, and the most popular programming languages that make it all possible.

For the first time in the history of Developer Economics, VisionMobile asked developers how much they earn in salaries and contractor fees, to explore what projects and types of development are more lucrative around different locations. What’s more, the report uncovers how technology battles continue on the web front with Angular vs React Javascript, Amazon Web Services is in a price war with their public cloud competitors, the IoT market is underdeveloped and highly fragmented, and Machine Learning developers are striving to identify what is the ideal programming language to use.

Welcome to the full rundown of the State of the Developer Nation Survey (November-December 2016) prize-draw winners. Below you’ll find a table comprised of both the email addresses and countries of all the people that won (the emails are obfuscated for security reasons).

The State of the Developer Nation Survey (H2 2016) was by far the largest in participation. The best way to illustrate this is by an infographic, highlighting important facts and figures.

Building strategies for user acquisition and retention are the two major tasks for dev teams after they have built an app, and analytics helps understand exactly what is happening and how to keep building traction. From there, new possibilities can emerge that will help you grow your user community even stronger and help you identify novel ideas that may offer you a winning edge.

Foursquare has already done the hard work of finding matching restaurants, so the trickiest part of building this MVP is finding a way to generate structured data from natural language. The great thing about tools like wit, LUIS, and api.ai is that they make this part so easy that you can build an MVP like the above in an afternoon. In our experience, 3rd party tools are an excellent way to build quick prototypes. You could just as quickly build a bot to find videos with the YouTube API, or products from Product Hunt.

Ragot said new dev teams can even just focus on one metric: “If there is one KPI, according to my experience, that tells you everything, it is “Retention at Day X”. D1 retention is how many people come back to your app in the same day after they install it. I am always looking at D1, D3, D7, D14 and D30. If you put all of your effort into measuring this, you have good analytics that is a mix of retention and acquisition.”

So after you’ve built an app, the first task is to position it so that your potential users start downloading it. User acquisition is all about getting app downloads. After downloads start climbing — even a slow increase is okay as long as it is steady — then it is important to start focusing on retention: getting users to start integrating your app into their habits so they reach for your app regularly.

Increasing user acquisition for your app starts with app store optimization. 30% of downloads occur after someone has searched by keywords in Google Play. So getting noticed within the app marketplace can already drive up user downloads before looking at any other type of promotion.
