Verdict
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.
