Certus·Golf

Know your
game.
Stop guessing.

cer·tus · /ˈkɛr.tʊs/ · adj. — certain; settled; sure.

Trace every swing. Measure every stroke. Analyze every hole. Certus turns feel and guesswork into numbers you can trust.

On opening · what it already knows

It has read your
rounds before you ask.

The three pillars feed one engine. Open the app and it has already been through every round you've logged, found the patterns, and picked the two worth telling you about.

Not a dashboard of numbers to interpret. A read on your game, in a sentence you can act on.

HomeReal capture
A Certus round recap reading: approach play finally showed up, but the putter cost you four shots. It credits +1.9 SG approach on 14 of 18 greens, then charges −2.1 SG putting with three three-putts, naming holes 3 and 14, above the round's traditional stats.
