About Kairo: Lock in with Friends
Become who you keep saying you'll be. Read more. Walk more. Get off your phone. Wake up earlier. Kairo turns the things you keep promising yourself into tiny daily habits you prove every day, with your friends by your side. HOW IT WORKS • Tell Kairo what you keep saying you'll do. • Kairo makes it small enough to start today, like 1 page a day or 5K steps. • Prove it with a photo, your steps from Apple Health or your screen time. • Your friends see your proof and cheer you on. BETTER WITH FRIENDS • Make a pact with a friend and keep each other going. • Start a challenge: 7 days, 30 days, or make your own. • See your friends' proofs live on your Home Screen with widgets. • React and chat when someone shows up. YOUR KAIRO, YOUR WAY • Pick the eyes, the mouth and the emojis around your Kairo. • Choose a scene and paint it in your colors. • Earn coins every time you show up and spend them on new looks. OFF DAYS HAPPEN Kairo has 4 lives, so one missed day isn't the end. Come back and keep going. WAKE UP EARLIER Alarms with a mission: math, shake, push-ups or a photo of an object. No more snooze. START IN A MINUTE No sign-up needed. Start as a guest and save your account anytime, so you never lose your Kairo or your streak.
