# dB Calculator vs Float

The clearest difference is update cadence: Float at monthly against dB Calculator's every 5 months. Float also leads on ratings volume (431 vs 3) and rating (4.6 vs 4.3). dB Calculator's advantage is monetization model (free vs freemium) and iOS requirement (10.0 vs 15.6). On price, review sentiment, ads and in-app purchases there is nothing between them.

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

Float holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: Float has 431 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 43% of dB Calculator's written reviews are positive against 36% of Float's, so the app with the better star average is not the one people write more warmly about.

dB Calculator ships an update every 5 months, Float monthly. The most recent releases landed on September 30, 2026 and September 23, 2026 respectively.
