# Henle Library vs Tambu

The clearest difference is review sentiment: Tambu at 100% against Henle Library's 34%. Tambu also leads on rating (5.0 vs 2.9) and update cadence (every 9 days vs every 2 months). Henle Library's advantage is ratings volume (91 vs 2) and iOS requirement (13.0 vs 15.6). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Henle Library sells 8 one-off in-app purchases and Tambu sells 1 in-app purchase, starting at $1.00 per month. Whichever you choose, the download price is not the number that matters.

Tambu holds the better App Store score, 5.0 against 2.9. That said, the two scores are not equally well evidenced: Henle Library has 91 ratings behind it against 2, so its average is the more settled of the two.
