I can't use the box calculator on my phone now. iPhone 5s ### 4/5 — DD toolkit is a one of a kind. *2013-08-26, version 1.0.4* Look no further for technical audio info. Great little app. ### 4/5 — Awesome app!!!! *2013-04-15, version 1.0.3* This things Definite Must have for any audiophile ### 4/5 — Great app but needs update *2013-03-15* You can't click the calculate button for the box calculator ## Most critical reviews (10 lowest-rated) ### 1/5 — Box calculator does not work *2023-08-18, version 2.0.2* Every time I start the app on IOS it looks off and the box calculator does not work app has massive bugs till it’s fixed no point using it ### 1/5 — Box design program *2022-04-12, version 1.1.4* Box design program is only good for a square box. Don’t need a program for that. Truck boxes are not square, most custom systems the boxes are not square unless you just throw a box in your trunk and there is nothing custom about that. ### 1/5 — Doesn’t work. *2020-02-07, version 1.1.4* App will time out. Calculator does what it wants to. App is garbage ### 1/5 — Please update *2017-11-26, version 1.1.4* I try to enter my info in the box building part but the keypad comes up and I can’t hit calculate because the keypad is in the way and there’s nothing I can do ### 1/5 — Broken *2014-02-21, version 1.0.5* The latest update has broken the wattage calculator, which makes this app useless. I am no longer able to enter the volts. I wish I can return to the previous version. ### 1/5 — Disappointing... *2013-03-16, version 1.0.1* The Kicker, Rockford, and JL apps offer more features. This app is pretty useless and must've been rushed out before being tested. If you have either of the other apps don't waste your time/storage on this. ### 2/5 — Faulty *2016-08-04, version 1.1.3* Latest update doesn't allow me to close down the keyboard on box calculator ### 2/5 — Doesn't work right with I5 *2013-04-07, version 1.0.1* After inputting dimensions into box calculator, u can't click calculate because the number pad doesn't disappear. ### 3/5 — Useful *2013-05-07, version 1.0.4* This app has some basic, but usefull tools. Best tone generator I've used . The swipe feature is nice, and it has a flashlight. I'm ready for more tools. ### 4/5 — Good app *2017-12-03, version 1.1.4* This is a nice app for figuring out the voltage to set your amp. The box size is nice just pick you music style 1st or the screen locks up. That’s why I give it 4 stars and not 5 ## Most praised reviews (10 highest-rated) ### 5/5 — Need bug fix *2026-04-14, version 2.0.2* It keeps crashing on me guys. I'm not gonna lie it's pretty frustrating tryin to build a box, I still won't go anywhere else though. If yall want real sound go get some DD AUDIO fr. If you don't have it, you're gonna stay mad like I did lol DD Audio will be in my home and ride for the rest of my life. Real talk guys ### 5/5 — Excellent *2022-02-26, version 1.1.4* Excellent app ### 5/5 — Thank you DD *2020-12-14, version 1.1.4* This is a nice app I used it to build a sub box for 1 12” deaf bonce 3012 apocalypse sub to install in a 2015 Lexus sound really good ### 5/5 — Handy app to have for a basshead *2020-04-30, version 1.1.4* Love the app so easy and handy calculators on hand ### 5/5 — DD is severely underrated *2015-06-24, version 1.0.6* I am a massive fan of DD Audio. They make incredible, competition-grade products. Why they're not more popular than Kicker, I'll never know. I like to compare Kicker to Mustang, and DD to Lamborghini. While they're both pretty cool sports cars, I would never take a Mustang to a competition with any of the real big dogs. ### 5/5 — DD *2013-06-15, version 1.0.4* Amazing app, very helpful ! DD4life. ### 5/5 — Awesome App. *2013-05-04, version 1.0.4* This app is awesome! Great layout and the swipe function makes for ease of use. I especially like that you can play test tones and swipe to the clamp page and back! ### 5/5 — DD9515i-D2 owner in New Zealand *2013-05-03* Awesome invention going to use this to help myself to build my own box for my sub. Boxes I built before have not did the job ### 5/5 — Отзыв *2013-05-03, version 1.0.4* Хорошая программа, но нет так функциональна как хотелось бы ### 5/5 — Отличная программа *2013-04-21, version 1.0.4* Выручала не раз --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
