# SMART vs Image Scan

The clearest difference is ads: Image Scan at none against SMART's shown. Image Scan also leads on update cadence (every 6 days vs every 3 weeks) and iOS requirement (12.0 vs 17.0). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. SMART sells 10 in-app purchases, starting at $2.99 per month and Image Scan sells 4 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

SMART ships an update every 3 weeks, Image Scan every 6 days. The most recent releases landed on September 18, 2026 and August 17, 2026 respectively.
