"Green Slope" measures the slope and then predicts the break and aimpoint required for a putt. It's intended as a training aid, providing assistance with visualization and understanding of putts. Set the green speed, select pin direction, place the device on ground for three seconds, and read your putt. Using the internal iPhone and iPad motion sensors to assess the device orientation and attitude, the App measures slopes across and along the line of the putt. The estimated Fall Line direction and slope are then used to predict the likely break. Standard 'Aimpoint', 'Plays As', 'Fingers' and other tables are available from the menu. These can be adjusted for slopes, Stimp, past hole distance, and other parameters. The app then provides graphical overviews of selected putts with optional configurations. Since many phones have one or more camera lenses on the back preventing accurate slope measurements, Green Slope has been designed to be used with the phone is face down or face up on the green. Comprehensive help on app use is available from the menu button.

Read full description

The Golf Analysis Toolbox (tGAT) is the most comprehensive collection of tools available for serious golfers. Calculate real-time ball flights, master green reading, and track your shot dispersion to lower your scores. Finally, get precise physics-based calculations for how wind, temperature, altitude, elevation and slope affect your ball in motion—and practice targeted drills with built-in Strokes Gained tracking. CORE FEATURES - Green Reading System: Accurately get the exact aim for any putt with simple math, using the distance to the hole, side-slope, elevation (uphill-downhill), and stimp. - Live Weather & Wind Calculations: Directly see how wind, temperature, altitude, and ground-level affect your club selection using your own ball flight launch conditions. - Ball Flight Simulator: See how any ball flight is affected by wind and shot shaping in the full 3D Flight Simulator. SKILL TESTS & STATISTICS - Green Reading: Train your ability to estimate slope percentages and accurately predict how much break to play. - Putting: Drills for the important 3–10 ft range, start direction and distance control tests with in-depth statistics tracking. - Long Game Dispersion: Simple 1D wedge distance control tests and 2D dispersion tests for both approach and tee shots.
