# ThetaWave vs StudyFi

The clearest difference is review sentiment: StudyFi at 100% against ThetaWave's 55%. StudyFi also leads on ads (none vs shown). ThetaWave's advantage is rating (4.6 vs 3.7) and ratings volume (51 vs 6). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. ThetaWave sells 10 in-app purchases, starting at $19.90 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.

ThetaWave holds the better App Store score, 4.6 against 3.7. That said, the two scores are not equally well evidenced: ThetaWave has 51 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 55% of ThetaWave'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.

ThetaWave ships an update fortnightly, StudyFi every 2 weeks. The most recent releases landed on October 21, 2026 and October 9, 2026 respectively.
