UTR Sports

UTR Sports provides a global platform for everything pickleball and tennis, connecting players, coaches, clubs, and federations through one digital ecosystem powered by highly accurate ratings.

UTR by UTR Sports is a global rating system that promotes fair and competitive play across the tennis world. All players, regardless of age, gender, geography, or skill level, are rated on the same scale from 1.00 to 16.50 based on actual match results.

UTR gives players a real-time view of their true skill level, helps them track progress, discover level-based play, and expand their tennis network across age, gender, and geography. The rating is calculated using a player's eligible recent match scores and weighted performance data.

As the platform continued to grow, improving registration speed, payment convenience, and communication became a clear product priority for returning users across web and mobile touchpoints.

UTR Sports platform overview

Registration Friction

Closeloop evaluated the existing UTR Sports registration journey and uncovered key experience gaps across payments, repeat sign-ups, and event communication touchpoints.

01

No Saved Payment Method

Returning users could not save their card details for future event registrations, which created repetitive effort and unnecessary checkout friction.

02

Repetitive Checkout Steps

Players had to re-enter payment information for each registration, slowing completion and increasing the chance of drop-off.

03

No Wallet-Based Express Pay

The platform lacked Apple Pay and Google Pay, limiting the faster single-tap payment experience users now expect.

04

Limited Real-Time Notifications

Notifications relied too heavily on email, leaving room to improve how users received time-sensitive registration and event updates.

05

Settings and Registration Were Disconnected

There was no clean experience for saving, editing, and managing cards at the account level while keeping registration simple.

06

Existing Payment Flow Had to Stay Stable

New enhancements had to fit into the existing Stripe-based experience without disrupting the current payment process.

Registration Goals

Closeloop prioritized the most important repeat-user journeys, delivering meaningful registration and payment improvements without requiring a broader platform rebuild.

Save and Manage Cards

Let users securely store payment details and update them later from settings.

Speed Up Checkout

Reduce payment friction and make repeat registration faster for returning players.

Add Wallet Payments

Introduce Apple Pay and Google Pay for quick, single-tap registration payments.

User Research & Challenges

Discovery Phase

Reviewing the existing registration flow

Closeloop analyzed the existing UTR Sports platform to identify baseline issues in the registration experience, especially for returning users making repeat event payments.

The review showed that returning customers had no practical way to save their payment details for future event registrations. That gap made repeat registrations slower, created unnecessary friction in the checkout journey, and increased the likelihood of incomplete registrations.

Closeloop also identified a clear opportunity to improve registration convenience with Apple Pay and Google Pay, while strengthening event communication through more responsive real-time notifications in addition to email updates.

Key Challenges

Balancing convenience with implementation safety
  • Repeat-user friction: The biggest gap was the repeated entry of payment details during event registrations.
  • Secure card management: Users needed the ability to store and update cards from settings, not just during one transaction.
  • Checkout modernization: Apple Pay and Google Pay had to feel native to the existing payment experience.
  • Communication speed: Event updates needed stronger real-time delivery through SMS as well as email.
  • Low-disruption rollout: The Stripe flow needed to remain reliable while the new functionality was introduced.

Execution Approach

Closeloop approached the engagement as a focused product enhancement initiative, improving the user journey without disrupting the broader platform foundation.

1

Audit the Existing Journey

Mapped the registration and payment flow to pinpoint the biggest sources of user friction and drop-off.

2

Design Card Management

Added the ability to save, edit, and manage payment cards while keeping the experience intuitive for future registrations.

3

Extend Payments and Alerts

Integrated Apple Pay, Google Pay, and Twilio-powered SMS notifications to improve speed and communication.

4

Preserve Platform Stability

Updated the Stripe workflow carefully so the new experience felt seamless without disrupting the trusted payment foundation.

Frequently Asked Questions

No questions match your search.

When choosing a development partner, businesses should evaluate expertise in scalable architecture, industry experience, and proven case studies. Closeloop Technologies stands out by delivering high-performance platforms with a strong focus on user experience and scalability.

The UTR Sports platform is built on React for the web frontend, ASP.NET for the backend API, iOS Swift for the native iPhone app, and Android Kotlin for the Android app. Closeloop Technologies integrated Stripe for card management, Apple Pay and Google Pay for express wallet payments, and Twilio for real-time SMS notifications. This multi-platform tech stack ensured a consistent, high-performance experience across all devices used by players, coaches, clubs, and federations worldwide.

Integration timelines vary depending on the complexity of the existing payment infrastructure. For UTR Sports, Closeloop Technologies successfully integrated Apple Pay and Google Pay alongside the existing Stripe setup without disrupting the live payment flow — a non-trivial challenge that required careful API orchestration and regression testing across both iOS and Android platforms. For most established apps with an existing payment processor, a well-scoped Apple Pay and Google Pay integration typically takes 4–8 weeks, including QA and staged rollout.

UTR Sports users had to manually re-enter their card details every time they registered for a new event — even if they had paid before. There was no saved card option, no wallet-based express checkout (Apple Pay / Google Pay), and no real-time SMS notification system for event updates. These friction points were causing drop-offs in the registration funnel. Closeloop Technologies was engaged to redesign the checkout and notification experience while preserving the stability of the existing Stripe payment flow.

The most effective lever for increasing registration completion on a sports platform is reducing payment friction at checkout. Closeloop Technologies demonstrated this with UTR Sports: by adding saved card management, one-tap Apple Pay and Google Pay options, and real-time SMS notifications, the platform achieved a 20% increase in registration completion and 15% higher customer satisfaction. Key strategies include enabling express checkout for returning users, minimising re-entry of payment data, and keeping users informed through timely in-app and SMS communications.

Yes. Closeloop Technologies delivered the UTR Sports enhancements across four platforms simultaneously — the React web application, the ASP.NET API backend, the iOS Swift native app, and the Android Kotlin native app — all within a single coordinated engagement. This cross-platform capability is a core strength of Closeloop as a custom software development company in the USA, allowing product teams to ship consistent experiences to all user segments without running parallel, siloed development tracks.

The standard approach is to introduce a dedicated messaging service (such as Twilio) as a new integration layer that operates independently of the core application logic. Closeloop Technologies used this method for UTR Sports — building Twilio-powered SMS notifications into the event registration flow without altering the existing email notification infrastructure or requiring changes to the payment system. This additive architecture pattern allows teams to enhance communication capabilities incrementally, with no downtime and minimal risk to the production environment.

Following Closeloop's enhancements to the UTR Sports event registration system, the platform recorded measurable improvements across all three target metrics: a 20% increase in registration completion rates, a 15% improvement in customer satisfaction scores, and a 2× faster checkout experience for returning users. The UTR Sports team confirmed: "Closeloop helped us improve event registration with a faster, more convenient payment experience while keeping communication stronger and more responsive for our users."

Look for a development partner with proven experience across both web and native mobile platforms, a track record in payment integration (Stripe, Apple Pay, Google Pay), and the ability to work within existing system constraints without disrupting live users. Closeloop Technologies is a leading custom software development company in the USA with demonstrated expertise in sports tech, as evidenced by their work with UTR Sports — a global tennis and pickleball platform serving players, coaches, clubs, and federations worldwide. Verified reviews on Clutch and GoodFirms, a clear agile process, and HIPAA/PCI-compliant engineering practices are additional must-checks when evaluating vendors.
