# ThetaWave vs brAiny

The clearest difference is review sentiment: brAiny at 100% against ThetaWave's 57%. brAiny also leads on ads (none vs shown) and rating (5.0 vs 4.6). ThetaWave's advantage is ratings volume (50 vs 3). 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 brAiny sells 1 in-app purchase, starting at $12.99 per month. Whichever you choose, the download price is not the number that matters.

brAiny holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: ThetaWave has 50 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 57% of ThetaWave's written reviews are positive against 100% of brAiny's.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on September 22, 2026 and September 14, 2026 respectively.
