# SmartShaker 3 vs CoolFireSB

The clearest difference is rating: CoolFireSB at 3.4 against SmartShaker 3's 2.8. SmartShaker 3's advantage is update cadence (every 2 months vs every 4 months) and ratings volume (40 vs 7). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

CoolFireSB holds the better App Store score, 3.4 against 2.8. That said, the two scores are not equally well evidenced: SmartShaker 3 has 40 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 17% of SmartShaker 3's written reviews are positive against 9% of CoolFireSB's, so the app with the better star average is not the one people write more warmly about.

SmartShaker 3 ships an update every 2 months, CoolFireSB every 4 months. The most recent releases landed on September 19, 2026 and September 3, 2026 respectively.
