The only data-driven yardage book to help you play smarter !

The smart yardage book

No one wants to play with a phone on a golf course, so we invented a printable yardage book, powered by Articial Intelligence that calculates your strategic options on any course in the world, based on your data.

Plan what you play

Amateur golfers are usually playing with the hope to succeed with very hazardous shots, and too often regret it right after. They just can't know when a decision is too risky... Prepare your next round like a pro with our gameplan feature !

Do what you plan

Playing with an on-course strategy based on your probabilities will make you much more confident on the tee, and will diminish the risk of mishitting.

Track what you did

Track your shots easily without electronic device. No need for expensive and routine-breaking sensors. We automatically track your shots from your GPS trace and the list of shots, which takes less than 10 sec per hole after you leave the green. Or a little more if you tripled it ;).

Play like a pro !

Listen to Tiger say it himself, decide before you take the shot or pay the consequences !

Choose the right shot sequence,
among millions of possibilities

Our artificial intelligence algorithms will constantly update your profile, to calculate and compare all possible tactics for you on any hole in the world.
