About Checkin
Nobody should be alone on their GLP-1 journey.
Checkin is a free texting companion for people on GLP-1 medications. You track your shots, meals and weight by texting it, the same way you'd text a friend. It reaches out between appointments, helps you through side effects, and answers your questions from trusted medical sources, so you never have to figure it out alone.
About 1 in 9 American adults take a GLP-1 medication to lose weight (up from 1 in 33 in 2024), and millions more take one for diabetes, heart health or liver health. The problem: the medicine arrived faster than the support around it. Most people get a prescription and a short doctor's visit, and then they're on their own. The nausea after a dose. The shot-day nerves. The question at 11 pm that doesn't feel worth a doctor's appointment.
That gap matters. In a study of more than 125,000 people who started a GLP-1, about 2 in 3 of those without diabetes stopped within a year. Side effects and high cost are the main reasons people drop off.

Good help shouldn't be hard to find.
Most of what's out there is selling something, written for doctors, or a guess in a comment thread. Trustworthy help shouldn't depend on what you can pay or who you know.
So we made it free. For everyone on a GLP-1.
Meet Checkin.
A companion you text, the same way you'd text a friend.

- 3It keeps track.Your shots, meals and weight, logged just by texting. Your next appointment starts with the full picture.
- 4It knows its limits.Warning signs always get “call your doctor or 911.” It's an AI companion, not a doctor, and it says so.
