# ThetaWave vs Flashka

ThetaWave and Flashka both sit at 4.6 stars, but that hides the real split: 80% of Flashka's written reviews are positive against 55% of ThetaWave's. Flashka also leads on ratings volume (398 vs 51). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. ThetaWave sells 7 in-app purchases, starting at $21.99 per month and Flashka sells 4 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Flashka holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Flashka has 398 ratings behind it against 51, so its average is the more settled of the two. Written reviews point the same way: 55% of ThetaWave's written reviews are positive against 80% of Flashka's.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on November 11, 2026 and November 8, 2026 respectively.
