# Ziner vs FLAT RSS Reader

The clearest difference is rating: FLAT RSS Reader at 4.4 against Ziner's 3.7. FLAT RSS Reader also leads on in-app purchases (none vs 1). Ziner's advantage is ads (none vs shown) and update cadence (every 11 days vs every 2 months). On price and device support there is nothing between them.

Both are free to download. Ziner sells 1 one-off in-app purchase. FLAT RSS Reader asks for nothing beyond the download.

FLAT RSS Reader holds the better App Store score, 4.4 against 3.7. Both are backed by a comparable volume of ratings — 38 and 8 respectively. Written reviews complicate that: 66% of Ziner's written reviews are positive against 50% of FLAT RSS Reader's, so the app with the better star average is not the one people write more warmly about.

Ziner ships an update every 11 days, FLAT RSS Reader every 2 months. The most recent releases landed on October 24, 2026 and October 29, 2026 respectively.
