dB Calculator vs ArrayCalc Viewer
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

The d&b ArrayCalc Viewer app provides all project data for rigging a d&b audiotechnik loudspeaker system. Once the system has been designed, calculated and optimized in the ArrayCalc simulation software, all relevant project information can be shared via email, AirDrop, Dropbox or iTunes onto any iOS device. The d&b ArrayCalc simulation software is the simulation tool for d&b line arrays, column and point source loudspeakers as well as subwoofers. This is a comprehensive toolbox for all tasks associated with acoustic design, performance prediction, alignment, rigging and safety parameters. It is available as a native standalone application for both Microsoft Windows and Mac OS X operating systems. ArrayCalc Viewer main benefits: - All relevant rigging, setup and system information close to hand in a concise format - Any changes to the system design can be immediately distributed - Paperless and efficient - User friendly

Verdict
The clearest difference is rating: dB Calculator at 4.3 against ArrayCalc Viewer's 4.1. dB Calculator also leads on iOS requirement (10.0 vs 16). On price, review sentiment, ratings volume and update cadence 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.
dB Calculator holds the better App Store score, 4.3 against 4.1. Both are backed by a comparable volume of ratings — 3 and 8 respectively. Written reviews complicate that: 43% of dB Calculator's written reviews are positive against 50% of ArrayCalc Viewer'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, ArrayCalc Viewer every 4 months. The most recent releases landed on September 11, 2026 and June 10, 2026 respectively.
