# EOPAN vs HDReye

The clearest difference is review sentiment: EOPAN at 80% against HDReye's 29%. EOPAN also leads on monetization model (free vs free with in-app purchases) and iOS requirement (12.0 vs 15.0). HDReye's advantage is update cadence (monthly vs every 4 months). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. EOPAN sells 10 one-off in-app purchases and HDReye sells 4 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

EOPAN ships an update every 4 months, HDReye monthly. The most recent releases landed on June 1, 2026 and September 22, 2026 respectively.
