# Epson iProjection vs OSRAM DMX Wi

The clearest difference is rating: Epson iProjection at 4.3 against OSRAM DMX Wi's 2.3. Epson iProjection also leads on ratings volume (3.4K vs 4). OSRAM DMX Wi's advantage is review sentiment (43% vs 20%) and update cadence (every 2 months vs every 6 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Epson iProjection holds the better App Store score, 4.3 against 2.3. That said, the two scores are not equally well evidenced: Epson iProjection has 3.4K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 20% of Epson iProjection's written reviews are positive against 43% of OSRAM DMX Wi's, so the app with the better star average is not the one people write more warmly about.

Epson iProjection ships an update every 6 months, OSRAM DMX Wi every 2 months. The most recent releases landed on October 18, 2026 and October 6, 2026 respectively.
