# ESTKme vs FlowDown

The clearest difference is monetization model: ESTKme at free against FlowDown's paid. ESTKme also leads on iOS requirement (15.1 vs 17.0). FlowDown's advantage is update cadence (every 4 days vs monthly) and rating (4.3 vs 4.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

FlowDown holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: FlowDown has 29 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 67% of ESTKme's written reviews are positive against 75% of FlowDown's.

ESTKme ships an update monthly, FlowDown every 4 days. Both last shipped on November 4, 2026.
