# Boom Blast vs Patient Zero

The clearest difference is rating: Patient Zero at 4.6 against Boom Blast's 3.6. Patient Zero also leads on review sentiment (27% vs 16%) and ratings volume (5.1K vs 782). Boom Blast's advantage is ads (none vs shown) and update cadence (fortnightly vs every 4 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Boom Blast sells 10 one-off in-app purchases and Patient Zero sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Patient Zero holds the better App Store score, 4.6 against 3.6. That said, the two scores are not equally well evidenced: Patient Zero has 5.1K ratings behind it against 782, so its average is the more settled of the two. Written reviews point the same way: 16% of Boom Blast's written reviews are positive against 27% of Patient Zero's.

Boom Blast ships an update fortnightly, Patient Zero every 4 months. Both last shipped on November 8, 2026.
