# Deflection vs LightPDF Scanner

The clearest difference is price: LightPDF Scanner at Free against Deflection's $4.99. LightPDF Scanner also leads on update cadence (every 11 days vs every 6 weeks). Deflection's advantage is rating (4.6 vs 4.0) and in-app purchases (none vs 6). On review sentiment, ads, device support and iOS requirement there is nothing between them.

LightPDF Scanner is free to download; Deflection costs $4.99 up front. LightPDF Scanner sells 6 in-app purchases, starting at $4.99 per month. Deflection asks for nothing beyond the download.

Deflection holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Deflection has 115 ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 74% of Deflection's written reviews are positive against 79% of LightPDF Scanner's, so the app with the better star average is not the one people write more warmly about.

Deflection ships an update every 6 weeks, LightPDF Scanner every 11 days. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
