# Zen Pipe vs Flipflop Solitaire

The clearest difference is rating: Flipflop Solitaire at 4.0 against Zen Pipe's 3.3. Flipflop Solitaire also leads on ratings volume (712 vs 10). Zen Pipe's advantage is ads (none vs shown) and review sentiment (79% vs 53%). On price, update cadence, 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 Flipflop Solitaire sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Flipflop Solitaire holds the better App Store score, 4.0 against 3.3. That said, the two scores are not equally well evidenced: Flipflop Solitaire has 712 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 79% of Zen Pipe's written reviews are positive against 53% of Flipflop Solitaire'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, Flipflop Solitaire monthly. The most recent releases landed on October 17, 2026 and October 15, 2026 respectively.
