Verdict
The clearest difference is ads: Vault at none against S1lkPay's shown. Vault also leads on review sentiment (52% vs 38%) and monetization model (free vs ad-supported). S1lkPay's advantage is rating (3.5 vs 3.1). On price, ratings volume, update cadence 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.
S1lkPay holds the better App Store score, 3.5 against 3.1. Both are backed by a comparable volume of ratings — 17 and 21 respectively. Written reviews complicate that: 52% of Vault's written reviews are positive against 38% of S1lkPay's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
