# Epson iProjection vs Duet Display

The clearest difference is in-app purchases: Epson iProjection at none against Duet Display's 6. Epson iProjection also leads on ads (none vs shown). Duet Display's advantage is update cadence (every 3 weeks vs every 6 months) and review sentiment (46% vs 20%). On price, rating and device support there is nothing between them.

Both are free to download. Duet Display sells 6 in-app purchases, starting at $3.99 per month. Epson iProjection asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.3 for Epson iProjection against 4.4 for Duet Display. That said, the two scores are not equally well evidenced: Duet Display has 49K ratings behind it against 3.4K, so its average is the more settled of the two. Written reviews are what separate them: 20% of Epson iProjection's written reviews are positive against 46% of Duet Display's.

Epson iProjection ships an update every 6 months, Duet Display every 3 weeks. Both last shipped on September 30, 2026.
