# BugLens vs Perf

The clearest difference is ads: Perf at none against BugLens's shown. BugLens's advantage is ratings volume (55 vs 5) and iOS requirement (13.0 vs 17.0). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. BugLens sells 3 in-app purchases, starting at $4.99 per month and Perf sells 2 in-app purchases, starting at $19.99 per year. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for BugLens against 5.0 for Perf. That said, the two scores are not equally well evidenced: BugLens has 55 ratings behind it against 5, so its average is the more settled of the two.
