The Open app serves as the official digital companion for golf's oldest championship, providing comprehensive coverage through multiple streaming channels and real-time data. Developed by The R&A, the application positions itself as the primary source for fans unable to attend the tournament in person, offering an immersive second-screen experience that captures both the competitive action and atmospheric elements of the event. Core functionality includes R&A TV with live coverage of featured groups, Live at the Range practice sessions, Open Radio commentary, and specialized par-3 channel coverage from iconic holes like the Postage Stamp. The app delivers real-time scoring updates, detailed tee time information, and an integrated live blog that provides contextual analysis alongside the raw data. These features combine to create a multi-layered viewing experience that caters to both casual viewers and dedicated golf statisticians. The interface employs a clean, golf-themed design with intuitive navigation between different coverage options. During tournament play, users can seamlessly switch between live video feeds, scoring updates, and supplementary content without losing their place in the action. The app demonstrates particular strength in its simultaneous streaming capability, allowing viewers to monitor multiple channels of content during peak competition periods when key players are spread across the course. User feedback consistently praises the app's comprehensive approach, with reviewer Naked bootleg (2023-07-20) noting 'brilliantly planned and executed comms team' and 'comprehensive resources and options.' Multiple reviews from 2022-2024 describe it as superior to other major championship apps, with One-SG (2022-07-17) declaring it 'the best app of all 4 majors hands down.' Some users like L.F.G.!!! (2023-07-21) appreciate the backward compatibility for older devices, though this may indicate potential limitations in feature availability across all platforms. The application excels during the championship period but has limited utility during offseason months. Its strength lies in the depth of official content unavailable through third-party services, though this specialization means it serves primarily as a tournament-specific companion rather than a year-round golf application. The production quality and content breadth set a high standard for sports championship apps, though users seeking continuous golf content may need supplementary applications during non-championship periods.
