# Interview Master vs Learn R

The clearest difference is ads: Interview Master at none against Learn R's shown. Interview Master also leads on ratings volume (8 vs 1) and iOS requirement (12.0 vs 15.1). Learn R's advantage is rating (5.0 vs 4.8). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Interview Master sells 1 in-app purchase, starting at $3.99 per month and Learn R sells 4 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Learn R holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Interview Master has 8 ratings behind it against 1, so its average is the more settled of the two.

Interview Master ships an update fortnightly, Learn R every 3 weeks. The most recent releases landed on June 9, 2026 and September 9, 2026 respectively.
