Golf’s most influential figures all agree that managing the game’s mental rigors is the key to finding success in the sport. The great Bobby Jones famously quipped that competitive golf is played “mainly on a five-and-a-half-inch course—the space between your ears,” and in Tiger Woods’ How I Play Golf tell-all which dedicates a chapter to the golf’s psychological component, he revealed that his greatest weapon is his “creative mind.”

All four major winners this year have brought up the virtue of patience as a contributing factor to their victories. At this past weekend’s Wyndham Championship, eventual winner Joohyung Kim began his tournament with a humbling quadruple bogey on his first hole. The 20-year-old shrugged off the adversity and embarrassment of the blowup, played his way into contention and went on to top the leaderboard on Sunday in style with a dominating five-stroke victory.

“I stayed very patient this week. That was the thing,” he told CBS’s Amanda Renner in a post-round interview. “I felt like after that quad, once I started to laugh it off, I was in a better mental state. Instead of getting angry and depressed, I stayed in the moment,” Kim continued.

With millions of dollars on the line, top players often tap into the expertise of a mental coach when they need to get their head straight. The caliber of mindset required to muster up championship level patience can cost a pretty penny. Of course, the cost-benefit for recreational players hasn’t really been there causing casual golfers to pay short thrift to the business of sharpening their mental acuity but Golf Guru, a subscription-based app that launched in June, aims to change the dynamic.

During the early phases of product testing, they reached out to players on a handful of developmental tours across the pond including the Clutch tours, PGA EuroPro Tour and the Ladies European Tour.
