Verdict
The clearest difference is monetization model: Adobe Scan at free with in-app purchases against SCAN ACE · PDF Scanner App's subscription. Adobe Scan also leads on ratings volume (1.6M vs 39K) and chart position (#11 vs #187). SCAN ACE · PDF Scanner App's advantage is ads (none vs shown) and iOS requirement (16.0 vs 18.0). On price, rating, review sentiment and update cadence 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. SCAN ACE · PDF Scanner App sells 10 in-app purchases, starting at $2.99 per month and Adobe Scan sells 10 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.8 for SCAN ACE · PDF Scanner App against 4.9 for Adobe Scan. That said, the two scores are not equally well evidenced: Adobe Scan has 1.6M ratings behind it against 39K, so its average is the more settled of the two. Written reviews are what separate them: 87% of SCAN ACE · PDF Scanner App's written reviews are positive against 82% of Adobe Scan's.
Both ship on a similar rhythm, roughly fortnightly. Both last shipped on November 10, 2026.
