dB Calculator vs Float
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
dB Calculator
This app provides five distinct calculation tools for power levels, voltage, and signal reflection. It helps convert between various units like dBm, watt, and dB, and calculate VSWR and reflection coefficients.
- dBm and watt power level calculations
- Correlated and uncorrelated voltage calculations
- Unit conversion for dBm, dBW, mW, W, mV, V, dBV, dBµV, dBu
- Linear power/voltage ratios to dB conversion
- VSWR, reflection coefficient, and mismatch loss calculations

The dBCalculator software comprises five independent calculation tools: dBm Calculator: This tools helps to add and subtract an arbitrary number of power levels expressed in units of dBm and watt. Voltage Calculator: This tools helps to add and subtract correlated and uncorrelated voltage levels. Unit Converter: This tool calculates for an entry using a unit such as dBm, dBW, mW, W, mV, V, dBV, dBµV and dBu the corresponding values for all other units, for individual impedance values. dB Converter: This tool converts linear power and voltage ratios to dB and vice versa. VSWR Converter: This tool converts reflection quantities such as Voltage Standing Wave Ratio VSWR, reflection coefficient, reflected power, return loss and mismatch loss. PLEASE NOTE: Calculations based on correlated vs uncorrelated levels yield very different results. If you see an unexpected result, please verify the uncorrelated/correlated setting of this app first! The dBCalculator software is based on the application note 1GP77: R&S dBCalculator by Rohde & Schwarz GmbH & Co. KG www.rohde-schwarz.com/appnote/1GP77

Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
