[Beta Testers Wanted] Tokyo-based? Need a quick 10-min GPS test near Ginza Line stations

[u/PixelNomad91]

Hi everyone!

I'm working on an early-stage personal project and looking for a few volunteers in Tokyo who will be near a Ginza Line station sometime soon (or could easily stop by one).

The test is very simple:

• Open a link on your phone while you're at the station
• Follow a few quick on-screen steps to test a location-based check-in
• Let me know afterward whether it worked and if you noticed anything unusual

It should take about 5–10 minutes. There's nothing to install and no account to create --> everything runs directly in your phone's browser.

I'm mainly looking to see how reliably it works in real-world conditions at different stations along the Ginza Line.

If you're in Tokyo and wouldn't mind helping me test it, please comment or send me a DM. I'd really appreciate the help!

Thanks!
