One for golfers to book tee times, the other for pros to manage lessons.
Golf's a weird one. On the one hand, it's played by obsessives who hoover up every new gadget going.
On the other, it's run by clubs that often reject new technology and modern business techniques.
New UK start-up mappt is aiming to shake things up with a 'programme to digitise the golf industry' via one consumer-facing and one professional-facing app.
The free 19th Hole Golf app (iOS and Android) lets golfers reserve tee times and book lessons with pros. It syncs to the booking systems of UK golf courses and will launch with connections to between 50 and 100 clubs, with 500 expected by September.
Tee times and golf lessons can be booked by time and geography first rather than merely by club and geography.
Meanwhile, Pro Time Golf lets golf pros accept bookings from golfers outside of club hours, straight in to their diaries and without the need for emails and phone calls.
mappt says it will charge around £20 a month for clubs to connect to its system.
In a sense, the firm is trying to do for golf what Hailo did for taxi booking. Until now, the UK's four million golfers mostly book by phone. And if they do reserve a slot online, the systems generally lack a real-time component, which makes booking unreliable.
Steve Weston, founder of mappt, said: “The industry is aware that golfers want to find and reserve tee times and golf lessons online and via mobiles. Despite this and the fact that a lot of clubs have the infrastructure in place to offer a range of service to consumers, a large number of clubs have been burned by their initial forays into commerce and doing business online.
"For many, it has also been deemed too expensive and too complicated for the returns they are likely to see. 19th Hole and Pro Time have broken all of these rules, offering a simple and cost-effective way to connect consumers to clubs and pros.”
