# Memory Skill Builder vs Harmony

The clearest difference is in-app purchases: Memory Skill Builder at none against Harmony's 10. Memory Skill Builder also leads on ads (none vs shown) and review sentiment (100% vs 74%). Harmony's advantage is ratings volume (835 vs 4) and chart position (#115 vs unranked). On price and device support there is nothing between them.

Both are free to download. Harmony sells 10 in-app purchases, starting at $4.99 per 7 days. Memory Skill Builder asks for nothing beyond the download.

Memory Skill Builder holds the better App Store score, 5.0 against 4.7.
