You should have a pro version which has no ads. Please send a screenshot to support@xplicittech.com ### 5/5 — Very useful. *2021-02-19* This app is great! I use the box calculators quite often to get a reference of enclosure volumes and port volumes. I especially love the tone generator as it can help find your peak frequency when metering. Lots of other calculators and handy info is packed in this app. Give it shot! **Developer response:** Thank you very much for your 5-star review!

I recommend this app to everyone from newbies to veteran Bassheads! **Developer response:** Thank you very much for your 5-star review!

I use this app all the time when helping people out online with designing boxes to fit in a given area. Would like to see updated with 4th and 6th order variations. Like using multiple chambers and it calculates the port from one chambers to the next and automatically remover that available area out of the next chamber. **Developer response:** Thank you very much for your 5-star review! If you have any suggestions for improvement or things to add, email them to thomas@xplicitcoding.com! ### 5/5 — Best app ever *2021-02-19* Still the best mobile app I have used for car audio.

I find myself constantly using this app. I have been into car audio for over 10 years and purchasing this app has helped me in many situations. Great job to the Xplicit team. ### 5/5 — Amazing app *2021-02-18, version 7.5* Great all in one application for car audio installations. ### 5/5 — Amazing app and continues to add more features *2021-02-18, version 7.5* Amazing app and continues to add more features ### 5/5 — Amazing App!!! *2021-02-18, version 7.5* This app is definitely a must have, super convenient and easy to use!!! ### 5/5 — Great app *2021-02-18, version 7.5* Great app to get information for car audio! Good job and keep up the hard work ### 5/5 — Love the new update *2021-02-18, version 7.5* I have been using this app for years multiple 150plus builds from just this app it has taught me a lot ty again ### 5/5 — Awesome ! *2021-02-18, version 7.5* Best app for any car audio related calculators ## Most critical reviews (10 lowest-rated) ### 1/5 — No sound *2022-11-19, version 7.5* The app just stopped working, every time I try to do a sweet or a tone burst nothing plays.. this needs fixed!! ### 1/5 — No preview *2022-10-01, version 7.5* Paid $2 just to see if this person made the box correctly and I put all the same info he did and got different tuning from the calculator and no preview to see how the box should look smh, wasted $2 ### 1/5 — No cut out sheet *2022-09-15, version 7.5* This app is old why is the cutout sheet coming soon you advertise it in the description. ### 1/5 — Waste of money *2019-07-25, version 7.0.0* I literally purchase this app to get a cut sheet. I have the same app on my phone but the free version and it gives you a cut sheet. I broke my android yesterday and I am currently using an iPhone so I was forced to pay for it and it was a complete waste of money. If I wanted to go through the work of using sketch up, I wouldn’t have paid for the app at all,I would’ve used another application that was free ### 1/5 — Good app no cut out *2019-02-15, version 7.0.0* I would give a five but no cutout defeats my purpose for buying ### 1/5 — Pointless. *2019-02-11, version 7.0.0* Completely pointless and useless, I guess a paid a dollar to have an app instead of using internet browser to get the same info. Nothing special here. ### 2/5 — Meh *2026-05-08, version 8.5.4* Only 3 sub brands in the database ### 2/5 — Great but could be better with a few tweaks. *2025-06-05, version 7.5* Love the app but I don't like how the cut sheet doesn't give port wall info on slot port and the 3d box is kinda pointless imo, electrical calculations are all over the place and inaccurate, hasn't been updated on apple in years but android gets frequent updates, but other than that it's good ig for simple box calculations and few other things but not much ### 2/5 — Putting the cart before the Horse. *2020-10-22* I have been looking for a comprehensive app for calculating the internal space required for a subwoofer based on a subwoofers parameters. I was disappointed to see that this app had no such thing. Hey Developer. How do I go about configuring what size a box should be when I don’t even know what the woofer needs? Take the simple, square box for instance. You ask for dimensions, bracing and woofer displacement but then you also ask for Fs, Vas and Qtc? What?.... The TSP is supposed to help me figure out the needed internal volume of an enclosure and it’s resonant frequency. How can I even start to “design” a box and start cutting when I don’t even know where to start!! Not everyone is a professional builder. This app makes that assumption. ### 3/5 — Update it plz *2025-01-08, version 7.5* Can you please get it update it been 3 year ago for apple update my buddy told me about this app and love it on android because it up to date but apple not ## Most praised reviews (10 highest-rated) ### 5/5 — A must for DIY car audio *2026-06-19* This app is great. It offers all kinds of design choices. However, I purchased this app and now I’m seeing ads. I’d like to see if I can have them removed as I shouldn’t have ads on an app I purchased that previously didn’t have ads. ### 5/5 — Awesome *2026-05-13, version 8.5.5* Great app for the beginner and pros! Absolutely a must have for anyone who wants a great multi functional car audio design app! JW. ### 5/5 — Download now *2026-04-21* If ur a bass head and love car audio this is a must have app! I love it and recommend to any and everyone! **Developer response:** Thank you! If you have any other thoughts, room for improvement, etc. please contact us at support@xplicittech.com! Much love from the UCAA team. ### 5/5 — Best box building app around *2026-04-15* Purchased this app before it went free about a year ago and have used it to build three different enclosures. All sounded great and got down just like I wanted them to. Good folks this is how honest they are. Since I paid $1.99 for the app before it went free they upgraded my plan to pro user unlocking tons of perks because they are solid folks. Y’all gotta try it out **Developer response:** Thank you! If you have any other thoughts, room for improvement, etc. please contact us at support@xplicittech.com! Much love from the UCAA team. ### 5/5 — The best I’ve played yet! *2022-12-04* So far only complaint is how hard and dense the game gets so fast. Legendary characters don’t come fast at all. However the game is the best I’ve played so far ### 5/5 — Great app *2022-09-05, version 7.5* Love this app, have been using it since it was released. ### 5/5 — Great App *2022-08-19, version 7.5* Has been amazing helping me design boxes and understanding displacement and port area ### 5/5 — amazing app *2022-01-02, version 7.5* the only thing i would recommend in the faq’s is information on 4th and 6th order walls. or a wall tab in general. ### 5/5 — This app is good but needs one thing *2021-03-16* I love this app very useful. One thing I would like for you guys to add is how to wire midrange and midbass speakers to a 4 channel amp the same way you guys show the “how to wire subs” tutorial. ### 5/5 — Best app and tool available *2021-02-19* Use the app daily, helps me with quick designs for customer builds and reference when I need it. Not going to find a more accurate app for enclosures period 10 stars all day long 👌💪 **Developer response:** Thank you very much for your 5-star review!
