# Hemi vs HZP (Hertz Player)

The clearest difference is monetization model: HZP (Hertz Player) at free with in-app purchases against Hemi's subscription. HZP (Hertz Player) also leads on review sentiment (59% vs 32%) and device support (4 vs 2). Hemi's advantage is rating (4.4 vs 3.9) and ratings volume (2.6K vs 111). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Hemi sells 2 in-app purchases, starting at $14.99 per month and HZP (Hertz Player) sells 6 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Hemi holds the better App Store score, 4.4 against 3.9. That said, the two scores are not equally well evidenced: Hemi has 2.6K ratings behind it against 111, so its average is the more settled of the two. Written reviews complicate that: 32% of Hemi's written reviews are positive against 59% of HZP (Hertz Player)'s, so the app with the better star average is not the one people write more warmly about.

Hemi ships an update every 2 weeks, HZP (Hertz Player) fortnightly. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
