ReceptionRating · Positive reviews · Number of ratings

Data Structures Interview Ques 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. Written reviews complicate that: 0% of Data Structures Interview Ques's written reviews are positive against 88% of Interview Master's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Data Structures Interview Ques ships an update every 47 months, Interview Master fortnightly. The most recent releases landed on August 14, 2026 and September 16, 2026 respectively.
