Verdict
The clearest difference is update cadence: DNS Client at every 3 weeks against BLE Spy's every 8 months. DNS Client also leads on ratings volume (145 vs 4) and price ($0.99 vs $4.99). On rating, ads, in-app purchases and chart position there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
BLE Spy costs $4.99 and DNS Client $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.
BLE Spy holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: DNS Client has 145 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 50% of BLE Spy's written reviews are positive against 64% of DNS Client's, so the app with the better star average is not the one people write more warmly about.
BLE Spy ships an update every 8 months, DNS Client every 3 weeks. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
