# Duos vs Interview Prep

The clearest difference is review sentiment: Duos at 100% against Interview Prep's 0%. Duos also leads on rating (5.0 vs 4.6) and update cadence (every 5 days vs monthly). Interview Prep's advantage is ratings volume (5 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Duos sells 4 in-app purchases, starting at $19.99 per month and Interview Prep sells 2 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Duos holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Interview Prep has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of Duos's written reviews are positive against 0% of Interview Prep's.

Duos ships an update every 5 days, Interview Prep monthly. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
