# 番茄ToDo vs CoStudy

The clearest difference is ads: 番茄ToDo at none against CoStudy's shown. 番茄ToDo also leads on ratings volume (4.8K vs 71) and update cadence (every 10 days vs every 3 weeks). On price, rating, review sentiment and in-app purchases there is nothing between them.

Both are free to download. 番茄ToDo sells 3 one-off in-app purchases and CoStudy sells 13 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for 番茄ToDo against 4.8 for CoStudy. That said, the two scores are not equally well evidenced: 番茄ToDo has 4.8K ratings behind it against 71, so its average is the more settled of the two. Written reviews are what separate them: 89% of 番茄ToDo's written reviews are positive against 93% of CoStudy's.

番茄ToDo ships an update every 10 days, CoStudy every 3 weeks. The most recent releases landed on September 25, 2026 and September 27, 2026 respectively.
