# Sentry Interactive vs NFC

The clearest difference is review sentiment: NFC at 60% against Sentry Interactive's 13%. NFC also leads on rating (4.3 vs 2.6) and update cadence (fortnightly vs monthly). Sentry Interactive's advantage is in-app purchases (none vs 2) and ads (none vs shown). On price and iOS requirement there is nothing between them.

Both are free to download. NFC sells 2 in-app purchases, starting at $0.49 per month. Sentry Interactive asks for nothing beyond the download.

NFC holds the better App Store score, 4.3 against 2.6. That said, the two scores are not equally well evidenced: NFC has 96 ratings behind it against 14, so its average is the more settled of the two. Written reviews point the same way: 13% of Sentry Interactive's written reviews are positive against 60% of NFC's.

Sentry Interactive ships an update monthly, NFC fortnightly. The most recent releases landed on September 30, 2026 and October 6, 2026 respectively.
