What's New in Ultimate Car Audio App

8.7.3

July 29, 2026

UCAA 8.7.2 is The brand-analytics update. Every brand page gets a new Sub Engagement dashboard: weekly and monthly sub views, top-performing subs, and box builds using your gear. Approved catalog subs auto-attribute to your brand — sign up years after the community added your subs and the full history still lights up. BRAND PRO drilldown: • Per-sub 90-day trend charts • Discovery → Build conversion funnel • Category benchmark vs the anonymized market median • Rising sub detector • Geographic breakdown • Audience mix — Pro vs free vs anonymous • Discovery surfaces — where viewers came from • Community activity signals • CSV export Also new: • Own more than one shop/brand/amp-repair page — request additional pages from My Pages • All owned pages now appear on My Pages instead of only the first per type • Pro cross-device preference sync (color theme, box finishes, favorites, advanced mode) • Meta-style account switcher on login with per-card remove • Dark mode on the login, register, and forgot-password screens • Country field at signup, auto-filled from your timezone • Tappable brand and series links on every subwoofer detail page • Review analytics now shown to Brand Pro members • Behind-the-scenes reliability improvements UCAA 8.7.3 adds a social layer. Follow other users right from their public profile — follower and following counts show on every profile. Every section of your profile is now individually hideable (last name, location, socials, join date, pages, achievements, published designs, subs) with a new "Followers only" tier that reveals content just to the accounts following you. Lock your profile down to just the essentials, or open specific sections only to your followers. Photos attached to saved box designs also upload in a more efficient format now — noticeably smaller files and faster loads with no visible quality difference. Plus various reliability and quality-of-life improvements.

A must for DIY car audio

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.

Awesome

Great app for the beginner and pros! Absolutely a must have for anyone who wants a great multi functional car audio design app! JW.

Best box building app around

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
