# Nielsen Mobile App vs CrossMark

The clearest difference is review sentiment: Nielsen Mobile App at 66% against CrossMark's 0%. Nielsen Mobile App also leads on in-app purchases (none vs 1) and ratings volume (539 vs 8). CrossMark's advantage is rating (5.0 vs 4.1). On price, update cadence, ads and monetization model there is nothing between them.

Both are free to download. CrossMark sells 1 one-off in-app purchase. Nielsen Mobile App asks for nothing beyond the download.

CrossMark holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: Nielsen Mobile App has 539 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 66% of Nielsen Mobile App's written reviews are positive against 0% of CrossMark's, so the app with the better star average is not the one people write more warmly about.

Nielsen Mobile App ships an update every 4 months, CrossMark every 2 months. The most recent releases landed on September 20, 2026 and August 18, 2026 respectively.
