# Data Usage Cat vs System Stats

The clearest difference is review sentiment: Data Usage Cat at 56% against System Stats's 0%. Data Usage Cat also leads on ads (none vs shown) and update cadence (every 3 weeks vs every 19 months). System Stats's advantage is rating (4.2 vs 4.0) and ratings volume (5 vs 1). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

System Stats holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: System Stats has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 56% of Data Usage Cat's written reviews are positive against 0% of System Stats's, so the app with the better star average is not the one people write more warmly about.

Data Usage Cat ships an update every 3 weeks, System Stats every 19 months. The most recent releases landed on August 7, 2026 and September 17, 2026 respectively.
