# TLS Inspector vs SPARK Scan

TLS Inspector and SPARK Scan are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

TLS Inspector ships an update monthly, SPARK Scan every 5 weeks. The most recent releases landed on October 14, 2026 and September 24, 2026 respectively.
