Description by Johannes Duo (from the App Store)

CK-IN, Build Consistency. Stay Accountable. Don't Skip.

CK-IN is a daily fitness accountability app built to help you show up even on the days you don't feel like it. This isn't about perfect workouts, calorie counting, or complicated plans. CK-IN is about consistency, commitment, and people who notice when you don't show up.
