# Zen Pipe vs Boo!

The clearest difference is rating: Boo! at 4.8 against Zen Pipe's 3.3. Boo! also leads on review sentiment (96% vs 79%) and ratings volume (201 vs 10). Zen Pipe's advantage is ads (none vs shown) and update cadence (every 2 months vs every 5 months). On price, in-app purchases, monetization model and device support there is nothing between them.

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

Boo! holds the better App Store score, 4.8 against 3.3. That said, the two scores are not equally well evidenced: Boo! has 201 ratings behind it against 10, so its average is the more settled of the two. Written reviews point the same way: 79% of Zen Pipe's written reviews are positive against 96% of Boo!'s.

Zen Pipe ships an update every 2 months, Boo! every 5 months. The most recent releases landed on October 21, 2026 and October 26, 2026 respectively.
