# black.com vs FlowCrypt

The clearest difference is in-app purchases: FlowCrypt at none against black.com's 1. FlowCrypt also leads on rating (4.0 vs 3.6). black.com's advantage is review sentiment (67% vs 50%) and update cadence (every 6 weeks vs every 4 months). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. black.com sells 1 in-app purchase, starting at $4.99 per month. FlowCrypt asks for nothing beyond the download.

FlowCrypt holds the better App Store score, 4.0 against 3.6. Both are backed by a comparable volume of ratings — 9 and 3 respectively. Written reviews complicate that: 67% of black.com's written reviews are positive against 50% of FlowCrypt's, so the app with the better star average is not the one people write more warmly about.

black.com ships an update every 6 weeks, FlowCrypt every 4 months. The most recent releases landed on September 17, 2026 and August 16, 2026 respectively.
