Emergency mode: In emergency situations, flipping the device will automatically redirect to other applications. Confusion method: Does anyone want to try their luck? Entering fake passwords leaves them confused. Parental control: Worried about children being messy? The children's mode allows them to only play the apps you want them to play with.

Verdict
The clearest difference is ads: 废纸圈 at none against Super App Lock：MystNote's shown. 废纸圈 also leads on iOS requirement (11.0 vs 16.0). Super App Lock：MystNote's advantage is update cadence (every 11 days vs every 3 months). On price, in-app purchases and device support there is nothing between them.
