Verdict

The call

The clearest difference is ads: Spark at none against Document Scanner's shown. Spark also leads on ratings volume (7.5K vs 108) and rating (4.8 vs 4.5). Document Scanner's advantage is update cadence (every 10 days vs monthly) and review sentiment (86% vs 73%). On price, in-app purchases and monetization model there is nothing between them.

Both are free to download. Spark sells 2 one-off in-app purchases and Document Scanner sells 3 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

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: 73% 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.

UpkeepUpdate frequency

Spark ships an update monthly, Document Scanner every 10 days. The most recent releases landed on November 13, 2026 and November 11, 2026 respectively.
