# Bug Identifier vs BugKnow

The clearest difference is review sentiment: BugKnow at 100% against Bug Identifier's 24%. BugKnow also leads on rating (4.7 vs 4.3). Bug Identifier's advantage is ratings volume (4.1K vs 15) and monetization model (ad-supported vs free with in-app purchases). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Bug Identifier sells 4 in-app purchases, starting at $4.99 per 7 days and BugKnow sells 2 in-app purchases, starting at $39.99 per year. Whichever you choose, the download price is not the number that matters.

BugKnow holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Bug Identifier has 4.1K ratings behind it against 15, so its average is the more settled of the two. Written reviews point the same way: 24% of Bug Identifier's written reviews are positive against 100% of BugKnow's.

Bug Identifier ships an update every 2 months, BugKnow every 3 months. The most recent releases landed on October 22, 2026 and October 7, 2026 respectively.
