A clear way to measure how you play indoors — so improvement is visible and competition stays fair across skill levels.
A simulator golf handicap is a way of measuring performance across simulator rounds so players of different skill levels can compete fairly and track improvement over time.
It is not an official WHS Handicap Index, and SimCap is not affiliated with GHIN. It is a simulator-specific index for the indoor game — built so your posted rounds mean something when you play again next week, at another facility, or against someone with a different skill level.
GHIN tells you about your outdoor game. SimCap tells you about your simulator game.
GHIN and the World Handicap System govern authorized outdoor rounds under their own rules. Simulator golf has different conditions and mechanics — putting modes, pin positions, wind settings, mulligans — that outdoor systems were not designed to weigh the same way.
If you need an official outdoor Handicap Index, GHIN is the answer for that world. If you want a portable index for how you actually play on the sim, that is what SimCap is for.
Conceptually, SimCap builds a WHS-style differential from your score, the course rating, and the slope. That differential is then adjusted for simulator-specific conditions — putting, pin placement, wind, and mulligans — so the result reflects how the round was actually played.
Your index is shaped by your best-performing recent rounds, so recent form matters and one outlier does not define you forever. The goal is a number you can trust for matches, leagues, and tracking whether you are getting better indoors.
Some courses have stronger difficulty data than others. Where SimCap can work from GSPro's own community difficulty data, the course is labeled Slope by GSPro. Where there is nothing usable to go on, SimCap falls back to a standard default and labels it Estimated.
We'd rather label an estimate than present a guess as verified fact.
Either way, posted rounds still count toward your index. The label tells you where the course difficulty came from — not whether the round “counts.”
See whether your indoor game is actually getting better — across courses, facilities, and setups.
Play people who are better or worse than you without inventing strokes on the fly.
Run stroke play, match play, scramble, and best ball with an index that everyone shares.

Native tools are useful inside their own ecosystem. If all of your golf lives in one platform, that history can already be helpful.
SimCap is for the problem that starts when you move between systems: one persistent identity and handicap across simulators and facilities. See One handicap. Every simulator.
