Open Golf App (OGA) — track every shot, get better at golf, free forever. OGA is a free, open-source golf-tracking app that does what paid apps charge $100+/year for: shot tracking with GPS, strokes-gained analysis against your handicap bracket, per-club shot-pattern dispersion, personalized practice plans, and live-round scoring. No ads. No paywalls. No premium tier. Built by golfers, for golfers. What you get • Track every shot live on the course with GPS-assisted ball and aim placement • Strokes-gained breakdown — off the tee, approach, around the green, putting — measured against your skill level, not a tour pro's • Shot-pattern dispersion — see your real spread and miss tendency per club • Personalized practice plans calibrated to your skill, goals, and the drills you can actually run • Detailed scorecard with par-relative scoring and round summaries • Custom bag — track your club lineup and carry distances • Log past rounds after the fact, or track live as you play • Free forever, open source, no in-app purchases What makes OGA different • Skill-calibrated: a 14-handicap's strokes gained compares to a 14 baseline, not to scratch • Explicit aim: you set your aim point before the shot, so your dispersion data is real — never guessed • Lie + slope per shot: filter your patterns by the lie you actually faced Why free? We believe getting better at golf shouldn't be paywalled. OGA is sustained by donations and the open-source community.
