Verdict
The clearest difference is ratings volume: Spark at 7.5K against Document Scanner's 108. Spark also leads on rating (4.8 vs 4.5) and device support (3 vs 1). Document Scanner's advantage is update cadence (every 10 days vs every 5 weeks) and review sentiment (86% vs 75%). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Spark sells 2 one-off in-app purchases and Document Scanner sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Spark holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Spark has 7.5K ratings behind it against 108, so its average is the more settled of the two. Written reviews complicate that: 75% of Spark's written reviews are positive against 86% of Document Scanner's, so the app with the better star average is not the one people write more warmly about.
Spark ships an update every 5 weeks, Document Scanner every 10 days. The most recent releases landed on October 14, 2026 and October 15, 2026 respectively.
