There's a lot a map doesn't tell you.

The collab item that sold out two hours ago. The station exit that's closed for construction this morning. A cherry blossom spot that's actually worth the detour today — but wasn't last week.

That kind of information exists. Someone knows it. They were just there. It just never had anywhere to go — until now. That's what Logger is for.

So, what is Logger?

Logger is a community map app where people log what they find and what gets in the way — pinned to the exact location it happened, visible to anyone nearby in real time.

Two types of logs

Discoveries

- "Found a quiet coffee shop only locals seem to know about."

- "Stumbled onto a limited-time anime pop-up in Shibuya."

Inconveniences & Tips

- "It was so crowded that I had to shorten my sightseeing plans."

- "Kyoto tip: Many major temples only accept cash."

Every log you leave adds to that pool of real, right-now information. Logs can include photos, text, or both — but they always come with an exact GPS location. That's really the whole point.

What's in the app

Timeline

A chronological feed of logs from your area. Filter by Discovery or Inconvenience. Just what was posted, in order.

Map

Green pins for Discoveries, orange for Inconveniences. Tap any pin to read the log. The map updates as new posts come in — no refresh needed.

My Page

Your full log history, mapped out. Look back on it later and it turns into a little record of everywhere you've actually been.
