# RTA Audio vs Car Audio

The clearest difference is ads: RTA Audio at none against Car Audio's shown. RTA Audio also leads on ratings volume (32 vs 4). Car Audio's advantage is rating (4.0 vs 3.5) and update cadence (every 2 months vs every 28 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. RTA Audio sells 1 one-off in-app purchase and Car Audio sells 2 in-app purchases, starting at $1.49 per month. Whichever you choose, the download price is not the number that matters.

Car Audio holds the better App Store score, 4.0 against 3.5. That said, the two scores are not equally well evidenced: RTA Audio has 32 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 59% of RTA Audio's written reviews are positive against 76% of Car Audio's.

RTA Audio ships an update every 28 months, Car Audio every 2 months. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
