Verdict
The clearest difference is review sentiment: DocLens Pro at 100% against Offline AI's 0%. DocLens Pro also leads on rating (5.0 vs 3.8) and update cadence (every 4 days vs every 4 months). Offline AI's advantage is ratings volume (9 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Offline AI sells 6 in-app purchases, starting at $4.99 per month and DocLens Pro sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Offline AI ships an update every 4 months, DocLens Pro every 4 days. The most recent releases landed on October 25, 2026 and October 18, 2026 respectively.
