# ThetaWave vs Axo

The clearest difference is review sentiment: ThetaWave at 55% against Axo's 0%. ThetaWave also leads on ratings volume (51 vs 1). Axo's advantage is ads (none vs shown) and rating (5.0 vs 4.6). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. ThetaWave sells 10 in-app purchases, starting at $19.90 per month and Axo sells 6 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Axo holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: ThetaWave has 51 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 55% of ThetaWave's written reviews are positive against 0% of Axo's, so the app with the better star average is not the one people write more warmly about.

ThetaWave ships an update fortnightly, Axo weekly. The most recent releases landed on November 4, 2026 and November 5, 2026 respectively.
