SnapCard vs SwingU: the difference in one line
SwingU: A free-for-life golf GPS app with a rangefinder, basic scorecard, stats, and a handicap tracker, plus paid Plus and Premium tiers for advanced features.
SwingU's main draw is that its core GPS rangefinder, basic scorecard, and stats are free for life, with paid Plus ($2.49/month) and Premium ($4.99/month or $59.99/year) tiers that add plays-like distances, wind and elevation adjustments, club recommendations, and strokes gained. It also offers a handicap tracker after a few rounds.
SnapCard approaches scoring from the other direction. Rather than tapping your phone on each hole, you keep the paper card the course gives you and snap one photo afterward; the AI reads every hole in about 5 seconds and updates your history and BirdieBank™ Index. There is no in-round phone use.
Both have reasonable free options, so the choice comes down to workflow: live GPS and on-phone scoring (SwingU) versus paper-and-scan (SnapCard).
