# IntroStat vs SmartSolve

The clearest difference is review sentiment: IntroStat at 92% against SmartSolve's 66%. IntroStat also leads on rating (4.9 vs 4.6) and iOS requirement (11.0 vs 15.1). SmartSolve's advantage is update cadence (fortnightly vs every 3 months) and ratings volume (3.6K vs 24). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. IntroStat sells 1 one-off in-app purchase and SmartSolve sells 13 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

IntroStat holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: SmartSolve has 3.6K ratings behind it against 24, so its average is the more settled of the two. Written reviews point the same way: 92% of IntroStat's written reviews are positive against 66% of SmartSolve's.

IntroStat ships an update every 3 months, SmartSolve fortnightly. The most recent releases landed on October 5, 2026 and October 13, 2026 respectively.
