# Functional Groups vs Organic Chemistry Practice

The clearest difference is review sentiment: Functional Groups at 100% against Organic Chemistry Practice's 0%. Functional Groups also leads on rating (4.9 vs 3.0) and ratings volume (21 vs 1). Organic Chemistry Practice's advantage is update cadence (monthly vs every 4 months) and iOS requirement (13.0 vs 15.0).
