# PAT vs StudyStash

The clearest difference is review sentiment: StudyStash at 100% against PAT's 28%. StudyStash also leads on update cadence (every 4 days vs monthly) and monetization model (free vs free with in-app purchases). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. PAT sells 3 in-app purchases, starting at $9.99 per month and StudyStash sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

PAT ships an update monthly, StudyStash every 4 days. The most recent releases landed on July 6, 2026 and June 4, 2026 respectively.
