About

Kinma

Features
Read full description

Kinma is a little companion that grows on real life, not grind. Photograph what you eat, and Kinma recognizes the dish and cuisine, then grows a little from it. Eat with friends by starting a table and inviting whoever's with you, and Kinma grows a different way, through connection instead of calories. HOW IT GROWS Every pet tracks two things: Nourishment, from the meals you log, and Sociability, from the tables you share. Which one you lean into shapes how your pet evolves. Eat solo and often, and it grows one way; gather people around a table often, and it grows another; balance both, and it finds a third form entirely. FACES Kinma remembers who you've shared a table with, building a quiet little archive of the people you actually eat with. Not a feed, not a follower count. Just a record of real meals with real people. NO GRIND, NO ADS Cosmetics unlock as your pet levels up. Kinma doesn't run ads and doesn't sell your data. SIGN IN YOUR WAY Use Sign in with Apple, Google, or an email and password, or skip all of it and just start. You can always add a real login later from Settings, from any device, without losing your pet. A pet that eats what you eat, and thrives when you eat together.
