Phigolf is a club-mounted sensor system for golfers who want course play and swing feedback without a photometric launch monitor, impact screen, or dedicated garage bay. The sensor clips to the club, talks to phone/TV apps, and fits apartments, offices, and travel better than a full enclosure stack.
Treat it as an entry / portable tier - useful for families, first indoor golf experiments, and small spaces where a real ball into a screen is impossible. Ball-flight physics will not match a floor photometric unit or radar; the product is convenience and entertainment more than fitting-grade data.
Software paths stay inside the Phigolf / partner app ecosystem (including WGT-linked editions where offered). You are not building a GSPro PC bay with this alone.
Phigolf fits when space and budget say “sensor on a club” before “build a room.” Spin numbers for club fitting, a permanent lounge, or real-ball impact practice need a different stack.
