# System Activity Monitors vs Data Activity Widget

The clearest difference is review sentiment: System Activity Monitors at 76% against Data Activity Widget's 25%. System Activity Monitors also leads on ads (none vs shown) and ratings volume (774 vs 7). Data Activity Widget's advantage is rating (5.0 vs 4.2) and update cadence (every 11 days vs every 3 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. System Activity Monitors sells 4 in-app purchases, starting at $3.99 per 7 days and Data Activity Widget sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Data Activity Widget holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: System Activity Monitors has 774 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 76% of System Activity Monitors's written reviews are positive against 25% of Data Activity Widget's, so the app with the better star average is not the one people write more warmly about.

System Activity Monitors ships an update every 3 months, Data Activity Widget every 11 days. The most recent releases landed on October 11, 2026 and October 3, 2026 respectively.
