# 番茄ToDo vs 错题本

The clearest difference is rating: 番茄ToDo at 4.9 against 错题本's 4.2. 番茄ToDo also leads on update cadence (every 10 days vs every 2 months) and ratings volume (4.8K vs 5). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. 番茄ToDo sells 3 one-off in-app purchases and 错题本 sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
