What is Coffee Filter?
An iPhone app for finding small, independent coffee shops. Instead of star ratings and reviews, shops are scored by how many people come back.
Where is it available?
We're starting in Southern California. You can browse shops anywhere we have them, and we'll add more cities over time. Coffee Filter is iPhone only for now.
What does "9 in 10 return" mean?
Of the people who checked in at a shop in the last 12 months, about 9 in 10 came back on another day. Someone who visits once counts as "not yet" only after 30 days, so a new visitor never drags a score down straight away.
A shop needs 20 people counted before it gets a score, so new or quiet shops show none yet. Scores update after every check-in.
How do check-ins work?
Tap Check In while you're at a shop. Your iPhone's location has to put you within about 75 meters of it, and each shop counts once per day. Come back on another day and it counts as a return.
When you join, you can name up to three regular spots. Those count as one check-in each, without your location.
Can other people see where I've been?
No. Your history, visit notes and favorites are private to your account. Shops only show totals (how many people came back, the top reasons they give, busy times), never who.
Why can I only have one account on my iPhone?
So nobody can boost a shop's score with extra accounts. Each iPhone can create one account. If you see "This iPhone already has a Coffee Filter account", sign in with the Apple ID you used before.
A shop is missing or its details are wrong
Use Submit a Shop from the menu, or Suggest an Edit on the shop's page. We review every submission by hand, and you'll see our answer in Notifications.
