Verdict

The call

The clearest difference is review sentiment: Stinger Compliance at 100% against Krystal's 35%. Krystal's advantage is rating (4.7 vs 3.0) and ratings volume (15K vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

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

ReceptionRating · Positive reviews · Number of ratings

Krystal holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: Krystal has 15K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 35% of Krystal's written reviews are positive against 100% of Stinger Compliance's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on November 9, 2026 and November 3, 2026 respectively.
