# ScanScan(白描) vs OCR文字识别

The clearest difference is ads: ScanScan(白描) at none against OCR文字识别's shown. ScanScan(白描) also leads on device support (4 vs 2). OCR文字识别's advantage is update cadence (every 5 days vs every 2 months) and iOS requirement (13.0 vs 15.0). On price and in-app purchases there is nothing between them.

Both are free to download. ScanScan(白描) sells 5 one-off in-app purchases and OCR文字识别 sells 1 in-app purchase, starting at $39.99 per year. Whichever you choose, the download price is not the number that matters.
