# PDF Doc Scanner vs Sight Bulb

The clearest difference is in-app purchases: Sight Bulb at none against PDF Doc Scanner's 10. Sight Bulb also leads on update cadence (every 2 weeks vs every 3 months) and review sentiment (10% vs 0%). PDF Doc Scanner's advantage is ads (none vs shown) and rating (2.9 vs 2.7). On price, ratings volume and device support there is nothing between them.

Both are free to download. PDF Doc Scanner sells 5 in-app purchases, starting at $6.99 per 7 days. Sight Bulb asks for nothing beyond the download.

PDF Doc Scanner holds the better App Store score, 2.9 against 2.7. Both are backed by a comparable volume of ratings — 238 and 211 respectively. Written reviews complicate that: 0% of PDF Doc Scanner's written reviews are positive against 10% of Sight Bulb's, so the app with the better star average is not the one people write more warmly about.

PDF Doc Scanner ships an update every 3 months, Sight Bulb every 2 weeks. Both last shipped on November 3, 2026.
