# Jellywatch vs Bug Identifier

The clearest difference is review sentiment: Jellywatch at 91% against Bug Identifier's 50%. Jellywatch also leads on in-app purchases (none vs 2) and rating (5.0 vs 4.6). Bug Identifier's advantage is ratings volume (81 vs 1). On price, update cadence and ads there is nothing between them.

Both are free to download. Bug Identifier sells 2 in-app purchases, starting at $4.99 per 7 days. Jellywatch asks for nothing beyond the download.

Jellywatch holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Bug Identifier has 81 ratings behind it against 1, so its average is the more settled of the two.
