Key Differences Between VibeCheck and Selin

Target Audience

VibeCheck is built specifically for men who want to understand and support their partners.

Actionable vs Informational

VibeCheck doesn't just tell you where your partner is in her cycle. It tells you what to DO about it. Every day, you get specific, actionable tips like "Energy might be lower today. Consider taking something off her plate" rather than just "Day 22 of cycle."

AI Personalization

VibeCheck's AI learns from your feedback. When you mark advice as helpful or not helpful, the system adjusts to better match what works for your specific relationship. Selin provides standardized content without this personalization layer.

Pricing

VibeCheck: Paid subscription. The subscription funds the AI that personalizes your experience.
Selin: Free with in-app purchases.
