# Zen Pipe vs Linko

The clearest difference is rating: Linko at 3.8 against Zen Pipe's 3.3. Linko also leads on update cadence (every 4 weeks vs every 2 months). Zen Pipe's advantage is ads (none vs shown) and review sentiment (79% vs 61%). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. Zen Pipe sells 1 one-off in-app purchase and Linko sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Linko holds the better App Store score, 3.8 against 3.3. Both are backed by a comparable volume of ratings — 10 and 26 respectively. Written reviews complicate that: 79% of Zen Pipe's written reviews are positive against 61% of Linko's, so the app with the better star average is not the one people write more warmly about.

Zen Pipe ships an update every 2 months, Linko every 4 weeks. The most recent releases landed on October 7, 2026 and October 14, 2026 respectively.
