# Document Scanner vs AI Storage Boost

The clearest difference is review sentiment: Document Scanner at 100% against AI Storage Boost's 0%. Document Scanner also leads on rating (5.0 vs 3.6) and monetization model (free with in-app purchases vs subscription). AI Storage Boost's advantage is ads (none vs shown) and update cadence (fortnightly vs every 2 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Document Scanner sells 2 in-app purchases, starting at $9.99 per month and AI Storage Boost sells 8 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Document Scanner holds the better App Store score, 5.0 against 3.6. That said, the two scores are not equally well evidenced: AI Storage Boost has 16 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of Document Scanner's written reviews are positive against 0% of AI Storage Boost's.

Document Scanner ships an update every 2 months, AI Storage Boost fortnightly. The most recent releases landed on June 11, 2026 and August 11, 2026 respectively.
