# StudyLog vs Stackd

The clearest difference is rating: Stackd at 5.0 against StudyLog's 4.2. Stackd also leads on ads (none vs shown). StudyLog's advantage is ratings volume (6 vs 1). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. StudyLog sells 4 in-app purchases, starting at $0.99 per month and Stackd sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Stackd holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: StudyLog has 6 ratings behind it against 1, so its average is the more settled of the two.

StudyLog ships an update every 10 days, Stackd fortnightly. The most recent releases landed on October 28, 2026 and October 24, 2026 respectively.
