dB Calculator vs TouchMix
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

TouchMix-30 Control is an app for iPad, iPad mini, iPhone and iPod touch that provides wireless control of QSC TouchMix-30 Pro digital sound reinforcement mixers. The app is not intended to perform any audio mixing or processing tasks on its own. Visit http://www.qsc.com for more information. When run on the iPad and iPad mini, the TouchMix-30 Control app closely follows the operational paradigm of the mixer. The iPad and the mixer GUI operate independently so it is possible for the iPad to act as an additional user interface that can display and control a set of functions completely different from those being controlled by the mixer’s screen and hardware. An alternate operation mode – Follow Mixer – is also available. With Follow Mixer engaged, the iPad follows the fader selection on the mixer. Touch a fader on the mixer and the iPad will display that channel’s Overview, EQ, Compressor, Sends or Gate screen. Touch a parameter on the iPad and the mixer’s rotary control will adjust it – or just drag on the iPad screen. When used without an actual TouchMix, the app acts as a demonstration of the mixer GUI and functionality. On the iPhone and iPod touch, the TouchMix Control app functions as a personal stage monitor mix control with the option to also remotely operate the mixer’s record and playback features as well as programmable user buttons. To prevent inadvertent adjustment of controls, the mixer operator may allow or restrict access to selected functions on a per-device basis. Features - Input channel processing (4-band PEQ, variable high & low-cut filters, gates, compressor) - Output channel processing (1/3 octave GEQ, 6-band PEQ, delay, variable high & low-cut filters, anti-feedback filters and wizard) - Two Real Time Analyzer (RTA) - Simple or Advanced mixer mode - Displays channel and output level meters - Channel and output levels - Effects and Aux (monitor) send levels - Select input presets from extensive library - Select and control 4 simultaneous effects - Input and output Mutes and Cues - Configure and control DCA and Mute Groups - Multi-track recorder arm, playback and transport - Two 24-channel Auto mixers - Scenes, Snapshots and Cue List Management - Includes TouchMix on-board Info system reference guide. - And more… Requirements - iPad, iPad mini, iPhone, iPod touch running iOS 16.5 or later - QSC TouchMix-30 Pro with version 3.0 or higher firmware installed. - QSC TouchMix-30 Pro connected to a Wi-Fi network (recommended). Visit http://www.qsc.com for more details on Wi-Fi connections. - Note that controlling a mixer with multiple iOS devices running different versions of the app is not recommended. - QSC, LLC Website TouchMix Support Application License Agreement.

Verdict
The clearest difference is rating: dB Calculator at 4.3 against TouchMix's 3.2. dB Calculator also leads on review sentiment (43% vs 32%) and iOS requirement (10.0 vs 12.0). TouchMix's advantage is ratings volume (52 vs 3). On price, update cadence, 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.
dB Calculator holds the better App Store score, 4.3 against 3.2. That said, the two scores are not equally well evidenced: TouchMix has 52 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 43% of dB Calculator's written reviews are positive against 32% of TouchMix's.
Both ship on a similar rhythm, roughly every 5 months. The most recent releases landed on October 16, 2026 and October 18, 2026 respectively.
