Verdict
The clearest difference is update cadence: Interview Master at fortnightly against Art of Stat's every 3 months. Interview Master also leads on rating (4.8 vs 4.4) and iOS requirement (12.0 vs 16.4). Art of Stat's advantage is monetization model (free vs free with in-app purchases) and review sentiment (100% vs 88%). On price, ratings volume, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Interview Master sells 1 in-app purchase, starting at $3.99 per month and Art of Stat sells 4 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
Interview Master holds the better App Store score, 4.8 against 4.4. Both are backed by a comparable volume of ratings — 8 and 13 respectively. Written reviews complicate that: 88% of Interview Master's written reviews are positive against 100% of Art of Stat's, so the app with the better star average is not the one people write more warmly about.
Interview Master ships an update fortnightly, Art of Stat every 3 months. The most recent releases landed on October 20, 2026 and October 30, 2026 respectively.
