# iStatistica vs System Stats

The clearest difference is rating: System Stats at 4.2 against iStatistica's 3.2. System Stats also leads on in-app purchases (none vs 1) and iOS requirement (14.0 vs 16.0). iStatistica's advantage is review sentiment (42% vs 0%) and ads (none vs shown). On price and device support there is nothing between them.

System Stats holds the better App Store score, 4.2 against 3.2. Both are backed by a comparable volume of ratings — 22 and 5 respectively. Written reviews complicate that: 42% of iStatistica'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.
