# Cosmo vs Hello Interview

The clearest difference is ratings volume: Cosmo at 858 against Hello Interview's 44. Hello Interview's advantage is review sentiment (100% vs 84%) and update cadence (every 6 days vs fortnightly). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Cosmo sells 4 in-app purchases, starting at $12.99 per month and Hello Interview sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Hello Interview holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Cosmo has 858 ratings behind it against 44, so its average is the more settled of the two. Written reviews point the same way: 84% of Cosmo's written reviews are positive against 100% of Hello Interview's.

Cosmo ships an update fortnightly, Hello Interview every 6 days. The most recent releases landed on October 28, 2026 and October 29, 2026 respectively.
