# IntroStat vs Statistics Solver

The clearest difference is ads: Statistics Solver at none against IntroStat's shown. Statistics Solver also leads on update cadence (fortnightly vs every 3 months) and ratings volume (407 vs 24). IntroStat's advantage is review sentiment (92% vs 67%) and rating (4.9 vs 4.6). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. IntroStat sells 1 one-off in-app purchase and Statistics Solver sells 2 in-app purchases, starting at $5.99 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: Statistics Solver has 407 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 67% of Statistics Solver's.

IntroStat ships an update every 3 months, Statistics Solver fortnightly. The most recent releases landed on September 18, 2026 and September 1, 2026 respectively.
