On most dating apps, your profile is a set of claims: photos you chose, prompts you polished, interests you tapped. Gritvit is built on a different input — your actual workout history — and that changes how matching works from the ground up.
Here's the full picture: what gets you into the pool, what other people see, and what keeps your profile visible once you're in.
Step one: earn your way in
You don't start swiping on day one. Matching sits behind a 7-day activity challenge — a week of real, tracked activity that you must complete before matching or even subscribing is available. That single gate is why the Gritvit pool looks different from any mainstream app: everyone in it has already demonstrated a week of verified activity.
The data comes from platforms you likely already use. Gritvit reads workouts from Apple Health on iOS or Google Health Connect on Android — Apple Watch, Garmin, and Fitbit sessions all count, and so do GPS workouts tracked with just your phone. Nothing is logged manually, so nothing can be typed into existence.
What every profile shows
Alongside the usual photos and details, every Gritvit profile carries two verified signals. The Fitness Score reflects recent training volume and consistency — it tells you whether someone is active right now, this month, not in some unspecified past. The Trust Level (L1 to L5) tells you how credible that data is: everyone starts at L1, phone GPS workouts can reach L3, and the L4 and L5 tiers require a wearable.
Read together, the two signals answer the questions a bio never can. "Is this person actually training?" — check the Fitness Score. "Can I believe it?" — check the Trust Level.
Staying visible is part of the deal
Matching on Gritvit isn't a one-time unlock. Your Fitness Score is a living number, and it decays when you stop: after 3 days of inactivity you get a warning, after 5 days the score starts dropping, and after 8 or more days your match visibility shrinks. Let it slide for 30 days and your Trust Level drops too.
That sounds strict until you see what it buys you. On other apps, a profile can sit in the deck for months after its owner stopped living the life it advertises. On Gritvit, visibility tracks reality — the profiles you're shown belong to people who are training now. The decay isn't a punishment; it's what keeps every match current.
What Gritvit never sees
All of this runs without your health data leaving your phone. Processing happens on-device, and your raw workouts, heart rate, GPS routes, and step counts are never uploaded. The only things that reach Gritvit's servers are the two aggregated numbers — your Trust Level and Fitness Score. That data is never sold or shared.
So the matching system knows exactly one meaningful thing about your training: enough to prove it's real. Everything else stays yours.
Why this produces better matches
Every layer of the system — the challenge gate, the verified signals, the decay — pushes toward the same outcome: a pool where fitness compatibility is measured, not claimed. You spend less time interviewing strangers about whether they really run and more time talking to people whose lifestyle already matches yours.
It's a smaller pool than the mainstream apps, and deliberately so. The filter is the product.
