Who it is for · Runners
For runners who want to know where they stand
Your watch knows your pace. It does not know that a sub-3 hour marathon puts you among roughly 1 in 15,000 people alive. GritCore does, and it verifies the run from the watch you already wear.

Common questions
Is there an app that shows how rare my marathon time is?
GritCore shows how rare running feats are, including a sub-3 hour marathon, and verifies them from the workouts your watch records.
Is GritCore a Strava alternative?
It is a companion rather than a replacement. Strava records and shares your runs; GritCore tells you how rare the big ones are and lets you duel friends over them. Your runs reach GritCore through Health Connect or Apple Health.
So how rare are you, actually?
GritCore is free on iPhone and Android.
