The DD Toolbox includes useful tools for setting up and analyzing high performance car audio systems. We understand installers have a lot going on while setting up a system, so the DD Toolbox layout was designed with this in mind. Easily switch between tools allowing fast and convenient use of the multiple tools. This allows you to do things like use the tone generator while punching numbers into the wattage calculator. DD Toolbox features: -Power Calculator for determining your systems actual output wattage and impedance -Tone Generator -DD Box Calculator Connectivity Note: DD Toolbox requires connectivity in order to download dynamic configuration data (allows us to add new speakers/specs to the calculator for example, without having to create a new build). If you attempt to run it without connectivity you may receive an error. Language Note: This version is capable of handling the native language of your device, but we have to provide a language file for it to use. If you're willing to help with translation to your language, please let us know, we'd love to make more languages generally available.

DD Toolbox holds the better App Store score, 3.6 against 3.0. That said, the two scores are not equally well evidenced: DD Toolbox has 12 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 63% of DD Toolbox's written reviews are positive against 100% of Airplus's, so the app with the better star average is not the one people write more warmly about.
DD Toolbox ships an update monthly, Airplus every 5 months. The most recent releases landed on September 24, 2026 and October 9, 2026 respectively.
