# Thea vs ThetaWave

The clearest difference is review sentiment: Thea at 95% against ThetaWave's 57%. Thea also leads on ads (none vs shown) and rating (4.9 vs 4.6). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Thea sells 2 in-app purchases, starting at $12.00 per month and ThetaWave sells 10 in-app purchases, starting at $19.90 per month. Whichever you choose, the download price is not the number that matters.

Thea holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Thea has 2K ratings behind it against 50, so its average is the more settled of the two. Written reviews point the same way: 95% of Thea's written reviews are positive against 57% of ThetaWave's.

Thea ships an update monthly, ThetaWave fortnightly. The most recent releases landed on September 23, 2026 and September 22, 2026 respectively.
