Chalk Golf keeps your golf in one place. Trace your shots, see your swing against a coach's lines and read the break on the green. Keep score by voice or by hand, run a society day with friends and keep track of practice and spending.

BALL TRACER
Pick a video of your shot, or film one in the app. Chalk listens for the strike, follows the ball and draws its flight over the clip. If it can't tell which ball is yours, it asks you to tap it. Reshape the flight, choose a tracer colour and save the video to share.
• Works from ordinary iPhone video, with a white or hi-vis ball
• Best filmed from behind the golfer, with the sky in frame and the sound on
• Free to try, with a daily limit. Saving the traced video requires Pro.

SWING STUDIO
Record your swing or pick a video you already have. Swing Studio draws the plane lines a coach would, steps through all ten positions from setup to finish, and scores the swing with the one thing to fix first, plus a cue and a drill to take to the range.
• P1 to P10, frame by frame
• Down-the-line and face-on views, each with its own checks
• Swing score, tempo, shoulder turn, hip turn and spine angle
• Compare two swings side by side, and track your numbers club by club
• Save the video with the lines drawn in, or share a still
It reads what the camera can see, not clubhead speed or ball flight. Requires Pro.

PUTT HELPER AND GREEN MAPS
Point your iPhone at the green. Chalk spots the ball and the hole, reads the slope between them and shows where to aim, how far to hit it and what the putt plays as.
• Aim in balls and cups left or right of the hole
• Hit-it and plays-as distances, slope, apex and fall line
• Green maps: scan a green once with a LiDAR iPhone and keep a contour map of its slopes
Requires Pro. The putt helper needs an iPhone that supports ARKit. Slope reads are most accurate with LiDAR (iPhone 12 Pro or a later Pro model); on other iPhones, distance is reliable but slope and break are rough estimates. Green maps need LiDAR. Reads are estimates. The Rules of Golf don't allow this kind of read in a competition round, so use it for practice and casual golf.

ON THE COURSE
• A scorecard for every round, built as you play
• Voice shot logging: hold the mic and say "seven iron, pulled it left, short of the green", and Chalk adds it to the card. Works offline.
• A satellite course map that follows the hole you're playing
• Front, centre and back yardages, and distances to bunkers and water, where the course is mapped

WITH FRIENDS
• Host a round or a whole society day, with several groups on one live leaderboard
• Stableford, match play, skins, Nassau, wolf, scramble, foursomes, greensomes and more, gross or net
• Nearest the pin, longest drive and a twos club
• Say the whole group's scores in one go, and sign each other's cards
• Share a live board with friends who aren't playing
• Plan a golf trip and run a season with an order of merit

BETWEEN ROUNDS
• Round history with score to par, holes played and notes
• Practice log for range sessions, short game, putting, lessons and fitness
• Tournament rounds kept apart from casual play
• Golf budget: green fees, entries and the cost of your membership per round
• A map of every course you've played, with your best score at each
