There are around 23 million surfers in the world. According to the available statistics, the surf industry generates $22 billion in revenue. Even though all these billions fall on sales of surf equipment, they indicate a stable demand and perspective not only for goods manufacturers but digital services as well. Just think how many more people want to surf a wave and how a specialized service can simplify finding a person who'll teach them standing on a surfboard. 

In this article, we're going to tell you the story of LetsSurf which helps beginning surfers finding a coach.

The story of LetsSurf

Technologies went so far as to allow consumers to find the needed service fast and without leaving their sofa. You can order pizza, book a flight, rent a car. And find a surfing coach!

Our customer saw a perspective in a business model that connects people willing to do various sports activities with instructors who can help them enhance their skills.

Why exactly surfing? This kind of sport is quite popular in Los Angeles where our customer comes from. In addition, there were no similar products in that area.

The absence of similar products and the belief in this model has encouraged our customer to create LetsSurf. With this decision, the customer contacted us and shortly afterward we started our cooperation.

Our team built this project from scratch and met the set deadline. To be precise, the scope of services we've provided to our customer is the following:

  • UI/UX design;
  • Web development;
  • Android development;
  • iOS development.

A deep dive into the features

This product represents a directory that connects beginning surfers with coaches from all around the US. The project has no breakthrough tech innovations behind yet it provides customers with a decent user experience.

Let's start at the very beginning and briefly overview the LetsSurf capabilities.


As soon as users launch an app, they have two options: sign up or search for a coach by entering a ZIP code or city where they want to take a surfing lesson.

Registration and coach search in LetsSurf mobile application

LetsSurf app: Users can look through coaches in their region before registration

This feature allows users overviewing coaches available in their region by distance and popularity. That's quite convenient as users can view coaches and search for them using various filters (e.g. price, age, session type) before continuing their interaction with the app. However, users have to sign up to request a session.

The sign up procedure is pretty standard. If users want to register via email, they should fill in a basic information (e.g. name, surname) and make up a password. Another option is to register via Google and all the required information will be automatically pulled from the account.

Book screen

As soon as users sign up, they get to the Book screen with the same functionality they could access to before registration. But there is one exception -- now they can request a session as they use the full-fledged app.

On this screen, users can also apply various search filters to get more relevant results and review coach profiles. Each profile contains a common information like gender, age, price, available equipment, etc. Besides, profiles may contain reviews from the previous learners.

Monetization strategy

Monetization is vital for any online product. That's why it's extremely important to understand which monetization strategy fits a project most of all.

LetsSurf is a directory and one of the most natural and best-fitting ways to monetize it -- charge the commission. The product retains 20% of the amount a user pays to coach for the lesson. Respectively, coaches keep 80% of the total cost.

Stripe was used to deal with online payment processing and implement this monetization strategy.

Technology stack behind LetsSurf

As you are already aware of features and peculiarities, let's consider technologies we've used to turn this project into life:

Mobile apps


Swift 4.1 was used to develop iOS application. At the moment of writing, it's the latest version of this programming language from Apple. Swift lets developers build apps for Apple OSes from watchOS and tvOS to iOS and macOS. Though Swift is a relatively young language, it's getting popular rapidly due to it's numerous advantages over Objective-C and many other popular languages.


It's a cross-platform mobile database that was used in iOS version of the mobile application. 


Kotlin was used to develop Android application. It has recently become the second official Android development language and is now actively developed and promoted by Google. The language has a bunch of advantages over Java allowing to build a more quality product in less time.


This database library was used in Android version of the application.
