# TutorOn vs Interview Master

The clearest difference is update cadence: Interview Master at fortnightly against TutorOn's monthly. Interview Master also leads on iOS requirement (12.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. TutorOn sells 2 in-app purchases, starting at $9.99 per month and Interview Master sells 1 in-app purchase, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

TutorOn ships an update monthly, Interview Master fortnightly. The most recent releases landed on September 14, 2026 and September 16, 2026 respectively.
