# Chrono PullUps vs Form

The clearest difference is in-app purchases: Form at none against Chrono PullUps's 1. Form also leads on rating (4.2 vs 4.0) and ratings volume (5 vs 1). Chrono PullUps's advantage is update cadence (weekly vs every 3 weeks) and iOS requirement (9.0 vs 15). On price, review sentiment, ads and device support there is nothing between them.
