Verdict
The clearest difference is price: Visual Periodic Table Chemie at Free against 4000基础必备英语单词's $2.99. Visual Periodic Table Chemie also leads on review sentiment (100% vs 85%) and update cadence (every 3 weeks vs every 2 months). 4000基础必备英语单词's advantage is in-app purchases (none vs 4). On rating, ratings volume, ads and device support there is nothing between them.
