Run for treasure.
Play it with your ears.
Treasures spawn on the real paths around you. Stereo pings tell you where — left, right, closer, warmer. Reach one before its timer runs out and it's yours. Eyes on the road, phone in your pocket, the whole time.
Hear a treasure hunt — wear headphones
The app's actual sounds and its actual voice: pings pan and rise as you close in, the coach speaks — music dips under him, then returns — and the find rings out. (Ambient track composed for this clip; on a run it's your music.)

01 · Sound
A running game designed for ears, not screens
Most running apps assume you'll look at them. Cologra assumes you won't — and builds the entire game out of sound.
Spatial treasure pings
Pings pan left and right by true bearing and rise in pitch as you close in. Close your eyes and you can point at the treasure.
A coach that speaks when it matters
Whether a chase is still winnable, when to let one go, when your own stride says you're tiring. No chatter, no filler.
Your music stays yours
Cues briefly lower your music, then get out of the way — playback is never paused.
Built for blind runners too
Eyes-free by design means screen-reader and voice-query support isn't an afterthought — it's the same product.
02 · Privacy
Your runs never leave your phone
Not "we take privacy seriously." Architecturally, literally: Cologra has no accounts and runs no servers. Routes, times, fitness — all of it lives on your device and nowhere else. Optional backup goes to a folder you pick — or your iCloud, once the iPhone build ships — off by default, behind a consent screen that says exactly what's in the file.
03 · Honesty
A coach that shows its work
Your fitness model is a Critical Speed fit of your own efforts — sports science older than the smartwatch, computed on your phone. Every headline number has a "why?" that opens the actual reasoning, citations included.
- No daily-streak guilt. Streaks count weeks here — rest days are training, and daily-run streaks are an injury mechanic. We refuse them.
- No fake metrics. A phone can't honestly measure ground-contact time or vertical oscillation, so Cologra doesn't pretend to. Cadence and stride length — measured against your own baseline, never a universal number.
- No made-up scores. No "readiness percentages," no proprietary mystery indexes. If we can't explain a number, we don't show it.

Compete with the only person who matters
Race your ghost
Start from a familiar spot and you're up against your own previous run — "you're 30 meters ahead of last Tuesday's you." No leaderboards, no strangers.
Explore every street
The app knows which paths around you you've never run, tells you where the unexplored ground is, and draws your coverage map — computed entirely on your phone.
Duo runs, no servers
Agree on a code word with a friend and you both hunt the exact same treasures, wherever each of you runs. Compare hauls after.
Own your data
One-tap export of everything you've earned. Works across platforms — even Android to iPhone. Delete the app and it's gone from the phone; any backups are yours alone to keep or delete.
05 · Idioma
Speaks 19 languages — out loud
Interface and voice coaching, both. The name is the mission: correr + lograr — run, achieve.
