# Lethe vs RAVON

The clearest difference is price: RAVON at Free against Lethe's $0.99. RAVON also leads on rating (4.8 vs 3.8) and ratings volume (84 vs 13). Lethe's advantage is chart position (#60 vs unranked) and update cadence (every 4 weeks vs every 2 months). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.

RAVON is free to download; Lethe costs $0.99 up front. Lethe sells 1 one-off in-app purchase and RAVON sells 17 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

RAVON holds the better App Store score, 4.8 against 3.8. That said, the two scores are not equally well evidenced: RAVON has 84 ratings behind it against 13, so its average is the more settled of the two. Written reviews point the same way: 65% of Lethe's written reviews are positive against 67% of RAVON's.

Lethe ships an update every 4 weeks, RAVON every 2 months. Both last shipped on October 16, 2026.
