[ Business context ]

Like many other startups, Phlex was born out of a realization of the problem faced by swimmers.

Its founders were four avid swimmers who realized that swimming lacked effective tracking and engagement.

At that time, no tool would unobtrusively provide meaningful feedback. And the only way to check heart rate was to put fingers on a neck and count each beat for six seconds. It was inconvenient, inaccurate, and inefficient.

Initially, the problem was considered from the point of view of professional swimmers. However, our client realized that was a much more common problem, extending to fitness swimmers as well.

So with growing demand, the founders began building the team needed to bring their idea to life.

When our client came to us, he already had a swimming training iOS app. So the Onix team was responsible for:

Ensuring an effective and transparent development process

Gathering requirements to define objectives and product scope

Upgrading an older iOS codebase and building an Android app from scratch

Creating an intuitive and appealing swimming workout app design

Building an Apple Watch companion tracking app

Providing an opportunity to collect and process the user’s data about their swim

Synchronizing information and data between watches and mobile app

Who this product is for

We've created an app for professional and non-professional swimmers who want to track their dynamic workout progress, create smart training plans, and achieve great results in swimming.

The app is deeply integrated with hardware devices

The app is deeply integrated with hardware devices provided by Phlex (Phlex EDGE)Polar (Polar devices), and Apple Watch that swimmers can wear to monitor their results during training.

Phlex solves the main goal

Phlex solves the main goal – collecting data and displaying vital metrics so swimmers can monitor and follow the progress dynamics and compare them to adjust their training with a data-driven approach.

Sophisticated flexible monitoring of training results

Tracking swimming technique and performance in a smart and convenient way

Hit great swimming goals using a data-driven approach

How Phlex works

We built a swimming tracker app to monitor training, set goals, and stay highly motivated. Phlex provides a streamlined experience and a sophisticated, flexible monitoring progress view to capture results and assess swims easily.

[ Solutions we provide ]

The top-level requirement was to collect and analyze the swimming data and synchronize it between watches and a mobile app.

The application collects and processes user data such as distance per second, speed, stroke rate, and heart rate.

That would allow swimmers to effectively and accurately track the training process and adjust the training plan with a more data-driven approach.

Swimming Training Data Collection & Analysis

Our experts enabled the app to gather and process users' data about swimming training.

The app now collects vital data like speed, stroke rate, and heart rate to track results and adjust the training process with a more data-driven approach.

Seamless Data Syncing Between Wearables & Mobile App

We ensured proper data syncing between watches and a mobile app that allows swimmers to monitor and track their swimming technique and performance in a smart and convenient way.

Accurate Stroke Technique Tracking

Our team built accurate technique tracking that allows monitoring every detail of swimmers' stroke during a workout to inform them about their improvements better.

Advanced Timing & Performance Metrics

We implemented efficient timing tracking to improve swimmers’ awareness and fully understand their training.

With scientifically validated accuracy, users can track such metrics as pace, interval, distance, and SWOLF.

Modern and solid onboarding process

Our designers refreshed the onboarding process and made it more up-to-date and uplifted.

The onboarding process is a user's first impression of the app, so our designers faced the challenge of reinforcing the app’s value and increasing the likelihood of its successful adoption.

Simple and intuitive feed

Our specialists made an easy-to-use swimmer’s log of activities that shows swims in chronological order.

We also provided access to users' training history and the ability to view related stats.

Moreover, we combined the tab of calendar activities with the swimming history to filter swims by date conveniently.

[ Results ]

As a result of Onix’s collaboration, our client now operates a reliable, well-performing mobile application that brings efficiency and fun to swimming workouts.

Phlex is a simple tool that enables swimmers to connect their wearable devices with a mobile app and collect motion data for accurately tracking their swimming. Using unique devices with motion data analysis, Phlex analyzes the user’s motions during training and, based on that, provides precise data about users' swimming technique and performance.

From now on, our client will change the sport of swimming by delivering an incredible training experience with real-time tracking and post-workout analytics and allowing users to enjoy every moment of their training.
