Verdict
The clearest difference is rating: Trace at 5.0 against Sentry NFC's 1.0. Trace also leads on update cadence (every 3 weeks vs every 14 months) and ratings volume (13 vs 1). Sentry NFC's advantage is in-app purchases (none vs 2). On price, ads, device support and iOS requirement there is nothing between them.

Sentry NFC ships an update every 14 months, Trace every 3 weeks. The most recent releases landed on June 4, 2026 and September 19, 2026 respectively.
