Why GritCore
Why measure rarity instead of volume?
Steps, rings and streaks reward showing up. They cannot tell you whether anything you did was rare. GritCore exists for the days that were: the marathon, the hundred kilometres, the plank you held for ten minutes.
Five reasons people use it
- It answers the question you actually have. Not "how much did I move" but "how many people have ever done this".
- Claims are checked. Recorded workouts verify distance, time and climbing. Nothing typed, nothing screenshotted.
- It is honest about its numbers. Every figure is an estimate and is labelled as one. Where no research exists, the app shows a count instead of inventing a percentage.
- It is private. No ads, no tracking, no location permission. Your route is never read. You can delete your account in the app, immediately and permanently.
- It is free, in English, French, Spanish, German and Dutch.
How is it different from Strava or Apple Fitness?
| Tracking apps | GritCore | |
|---|---|---|
| Records workouts | Yes | No, reads the ones you already recorded |
| Rewards | Volume and consistency | Rarity: how few people have done it |
| Comparison | Segments, rings, streaks | "About 1 in N people", worldwide |
| Competition | Leaderboards on routes | 1v1 duels and a monthly country table |
| Location data | Usually required | Never requested |
They work together: keep recording with the app you like, and let GritCore tell you when something you did was rare.
Before you attempt anything
Extreme feats carry a real risk of injury. GritCore describes feats; it does not coach anyone or judge whether they are ready, and nothing in it is medical advice. If you are unsure whether something is safe for you, speak to a doctor first.
Common questions
Is GritCore free?
Yes. There are no ads, no purchases and no subscription.
Does GritCore replace my running or cycling app?
No. Keep recording with the app you use; GritCore reads the workout from Health Connect or Apple Health when you want to verify a feat.
So how rare are you, actually?
GritCore is free on iPhone and Android.
