# Encyclopedia vs InsectLens

The clearest difference is rating: InsectLens at 5.0 against Encyclopedia's 4.4. Encyclopedia's advantage is ratings volume (15 vs 1) and device support (3 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Encyclopedia sells 1 one-off in-app purchase and InsectLens sells 13 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

InsectLens holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Encyclopedia has 15 ratings behind it against 1, so its average is the more settled of the two.

Encyclopedia ships an update weekly, InsectLens every 10 days. The most recent releases landed on October 11, 2026 and October 24, 2026 respectively.
