# BoomBoom.io vs COSMO PANIC

The clearest difference is review sentiment: BoomBoom.io at 100% against COSMO PANIC's 47%. BoomBoom.io also leads on update cadence (every 2 days vs weekly) and iOS requirement (11.0 vs 13.0). COSMO PANIC's advantage is rating (4.4 vs 1.0) and ads (none vs shown). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. BoomBoom.io sells 9 one-off in-app purchases and COSMO PANIC sells 27 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

COSMO PANIC holds the better App Store score, 4.4 against 1.0. That said, the two scores are not equally well evidenced: COSMO PANIC has 73 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of BoomBoom.io's written reviews are positive against 47% of COSMO PANIC's, so the app with the better star average is not the one people write more warmly about.

BoomBoom.io ships an update every 2 days, COSMO PANIC weekly. The most recent releases landed on October 6, 2026 and October 21, 2026 respectively.
