# OCR vs 极私语

The clearest difference is in-app purchases: 极私语 at none against OCR's 3. 极私语 also leads on device support (4 vs 2). OCR's advantage is update cadence (daily vs every 4 days) and iOS requirement (11.0 vs 16.0). On price and ads there is nothing between them.

Both are free to download. OCR sells 3 in-app purchases, starting at $0.99 per month. 极私语 asks for nothing beyond the download.

OCR ships an update daily, 极私语 every 4 days. The most recent releases landed on November 12, 2026 and November 13, 2026 respectively.
