The clearest difference is review sentiment: PlainsCapital Mobile Banking at 85% against Security First CU's 14%. Security First CU's advantage is rating (4.8 vs 3.5) and ratings volume (1.9K vs 8). On price, update cadence, 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.
Security First CU holds the better App Store score, 4.8 against 3.5. That said, the two scores are not equally well evidenced: Security First CU has 1.9K ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 14% of Security First CU's written reviews are positive against 85% of PlainsCapital Mobile Banking's, so the app with the better star average is not the one people write more warmly about.
Security First CU ships an update every 3 months, PlainsCapital Mobile Banking every 5 months. The most recent releases landed on November 1, 2026 and November 6, 2026 respectively.
