# Ivory vs Trouble Tree

The clearest difference is review sentiment: Trouble Tree at 100% against Ivory's 55%. Trouble Tree also leads on rating (5.0 vs 4.4). Ivory's advantage is monetization model (free with in-app purchases vs subscription) and ratings volume (28 vs 4). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Ivory sells 7 in-app purchases, starting at $6.99 per month and Trouble Tree sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Trouble Tree holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Ivory has 28 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 55% of Ivory's written reviews are positive against 100% of Trouble Tree's.

Ivory ships an update every 2 weeks, Trouble Tree fortnightly. Both last shipped on October 24, 2026.
