Features

Make walking
an adventure.

🗺️

A daily treasure map

A sealed bottle drifts to the shore. Open it to receive today's treasure map — one a day, an easy rhythm to keep.

🧭

Decode & walk

Decoding sets a destination from your current location, guides a walking route, and rewards you on arrival.

💎

A gallery to collect

Earned treasures go to your gallery. No duplicates — aim to complete each series across many rarities.

👣

Your footprints

Distance, steps, and streaks are recorded automatically — even free walks with no destination count.

🔒

Privacy first

Your GPS trail and precise location stay only on your device — never sent to any server.

🌗

Dark & light

A moonlit shore and a dawn shore — leather, brass, and parchment in two antique themes.

Philosophy

Not a location game —
a reward for walking.

No competition, no pay-to-win, no account.
Just a small daily reward that makes you think,
"Maybe I'll walk a little today, too."
Collect them all, and the full fixed set of treasures comes together.
