# NINJA Workspace vs PDF Scan and Sign Pro

The clearest difference is in-app purchases: PDF Scan and Sign Pro at none against NINJA Workspace's 5. PDF Scan and Sign Pro also leads on update cadence (every 4 days vs monthly) and rating (5.0 vs 4.7). NINJA Workspace's advantage is ratings volume (42 vs 1) and iOS requirement (12.0 vs 17.0). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. NINJA Workspace sells 5 in-app purchases, starting at $4.99 per month. PDF Scan and Sign Pro asks for nothing beyond the download.

PDF Scan and Sign Pro holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: NINJA Workspace has 42 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

NINJA Workspace ships an update monthly, PDF Scan and Sign Pro every 4 days. The most recent releases landed on November 2, 2026 and October 30, 2026 respectively.
