# 40X vs Perfect Stopwatch

The clearest difference is in-app purchases: 40X at none against Perfect Stopwatch's 5. 40X also leads on ads (none vs shown) and review sentiment (100% vs 86%). Perfect Stopwatch's advantage is update cadence (every 2 weeks vs every 7 months) and ratings volume (193 vs 6). On price, rating and device support there is nothing between them.
