# Study Quest vs Coban

The clearest difference is rating: Coban at 4.8 against Study Quest's 4.1. Coban also leads on update cadence (weekly vs monthly) and ratings volume (620 vs 18). Study Quest's advantage is ads (none vs shown) and iOS requirement (11.0 vs 15.0). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Study Quest sells 3 one-off in-app purchases and Coban sells 5 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

Coban holds the better App Store score, 4.8 against 4.1. That said, the two scores are not equally well evidenced: Coban has 620 ratings behind it against 18, so its average is the more settled of the two. Written reviews point the same way: 65% of Study Quest's written reviews are positive against 81% of Coban's.

Study Quest ships an update monthly, Coban weekly. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
