# Leaf Identification vs ThinkAssist

The clearest difference is review sentiment: ThinkAssist at 85% against Leaf Identification's 34%. Leaf Identification's advantage is ratings volume (1.4K vs 95) and rating (4.8 vs 4.6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Leaf Identification sells 3 in-app purchases, starting at $2.99 per 7 days and ThinkAssist sells 9 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Leaf Identification holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Leaf Identification has 1.4K ratings behind it against 95, so its average is the more settled of the two. Written reviews complicate that: 34% of Leaf Identification's written reviews are positive against 85% of ThinkAssist's, so the app with the better star average is not the one people write more warmly about.

Leaf Identification ships an update fortnightly, ThinkAssist every 4 weeks. The most recent releases landed on September 27, 2026 and September 28, 2026 respectively.
