# A vs Epson iProjection

The clearest difference is price: Epson iProjection at Free against A's $4.99. Epson iProjection also leads on rating (4.3 vs 2.3) and ratings volume (3.4K vs 3). A's advantage is update cadence (every 5 weeks vs every 6 months). On review sentiment, ads, in-app purchases and device support there is nothing between them.

Epson iProjection is free to download; A costs $4.99 up front. 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 3, so its average is the more settled of the two. Written reviews complicate that: 26% of A's written reviews are positive against 20% of Epson iProjection's, so the app with the better star average is not the one people write more warmly about.

A ships an update every 5 weeks, Epson iProjection every 6 months. The most recent releases landed on October 14, 2026 and October 18, 2026 respectively.
