Verdict
The clearest difference is in-app purchases: Folio at none against Silver Vault's 2. Folio also leads on iOS requirement (15.1 vs 18.0). Silver Vault's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 2 months). On price and device support there is nothing between them.
