# Source Code Reader vs DNS Client

The clearest difference is rating: Source Code Reader at 5.0 against DNS Client's 4.5. DNS Client's advantage is update cadence (every 3 weeks vs every 5 months) and ratings volume (146 vs 5). On review sentiment, ads, in-app purchases and chart position there is nothing between them.

Source Code Reader costs $1.99 and DNS Client $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Source Code Reader holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: DNS Client has 146 ratings behind it against 5, so its average is the more settled of the two. Written reviews split almost evenly too, at 63% and 64% positive.
