# RTA Audio vs DMX 24i

The clearest difference is rating: RTA Audio at 3.5 against DMX 24i's 2.0. RTA Audio also leads on ratings volume (32 vs 1). DMX 24i's advantage is in-app purchases (none vs 1) and update cadence (monthly vs every 28 months). On price, ads and device support there is nothing between them.

Both are free to download. RTA Audio sells 1 one-off in-app purchase. DMX 24i asks for nothing beyond the download.
