# 生字表 vs Science Tools

The clearest difference is in-app purchases: 生字表 at none against Science Tools's 1. 生字表 also leads on update cadence (every 5 days vs every 5 weeks). Science Tools's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Science Tools sells 1 one-off in-app purchase. 生字表 asks for nothing beyond the download.

生字表 ships an update every 5 days, Science Tools every 5 weeks. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
