# Micro vs Cal.com

The clearest difference is review sentiment: Micro at 100% against Cal.com's 55%. Micro also leads on rating (5.0 vs 4.8) and update cadence (every 10 days vs every 3 weeks). Cal.com's advantage is ratings volume (126 vs 1) and iOS requirement (15.1 vs 26.0). On price, ads, in-app purchases and monetization model there is nothing between them.
