# HDReye vs HDRI Studio

The clearest difference is update cadence: HDRI Studio at weekly against HDReye's monthly. HDReye's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. HDReye sells 4 in-app purchases, starting at $6.99 per month and HDRI Studio sells 3 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.

HDReye ships an update monthly, HDRI Studio weekly. The most recent releases landed on November 7, 2026 and October 31, 2026 respectively.
