Verdict
The clearest difference is monetization model: FNF App at free against LegitApp Authentication's free with in-app purchases. LegitApp Authentication's advantage is ratings volume (9.9K vs 1) and update cadence (weekly vs every 6 weeks). On price, rating, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
On the App Store both sit at effectively the same score — 4.9 for LegitApp Authentication against 5.0 for FNF App. That said, the two scores are not equally well evidenced: LegitApp Authentication has 9.9K ratings behind it against 1, so its average is the more settled of the two.
LegitApp Authentication ships an update weekly, FNF App every 6 weeks. The most recent releases landed on September 27, 2026 and September 22, 2026 respectively.
