# Lethe vs シノビスラッシュ

The clearest difference is price: シノビスラッシュ at Free against Lethe's $0.99. シノビスラッシュ also leads on rating (4.8 vs 3.8) and ratings volume (54 vs 13). Lethe's advantage is review sentiment (65% vs 44%) and chart position (#57 vs unranked). On update cadence, ads, in-app purchases and device support there is nothing between them.

シノビスラッシュ is free to download; Lethe costs $0.99 up front. Lethe sells 1 one-off in-app purchase and シノビスラッシュ sells 13 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

シノビスラッシュ holds the better App Store score, 4.8 against 3.8. Both are backed by a comparable volume of ratings — 13 and 54 respectively. Written reviews complicate that: 65% of Lethe's written reviews are positive against 44% of シノビスラッシュ's, so the app with the better star average is not the one people write more warmly about.

Lethe ships an update every 4 weeks, シノビスラッシュ monthly. The most recent releases landed on October 19, 2026 and October 7, 2026 respectively.
