# Knowunity vs StudyFi

The clearest difference is rating: Knowunity at 4.7 against StudyFi's 3.7. Knowunity also leads on update cadence (every 2 days vs every 2 weeks) and ratings volume (6.4K vs 6). StudyFi's advantage is ads (none vs shown) and review sentiment (100% vs 82%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Knowunity sells 29 in-app purchases, starting at $2.99 per month and StudyFi sells 16 in-app purchases, starting at $11.99 per month. Whichever you choose, the download price is not the number that matters.

Knowunity holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: Knowunity has 6.4K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 82% of Knowunity's written reviews are positive against 100% of StudyFi's, so the app with the better star average is not the one people write more warmly about.

Knowunity ships an update every 2 days, StudyFi every 2 weeks. The most recent releases landed on October 17, 2026 and October 9, 2026 respectively.
