Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
NICE DIGI holds the better App Store score, 2.7 against 2.0. That said, the two scores are not equally well evidenced: NICE DIGI has 36 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 22% of NICE DIGI's written reviews are positive against 25% of Blackview Security's, so the app with the better star average is not the one people write more warmly about.
NICE DIGI ships an update every 6 months, Blackview Security every 2 months. The most recent releases landed on September 15, 2026 and September 21, 2026 respectively.
