# AI Scanner vs Acid Interval

The clearest difference is ads: Acid Interval at none against AI Scanner's shown. Acid Interval also leads on rating (5.0 vs 4.6). AI Scanner's advantage is ratings volume (9.2K vs 1) and device support (4 vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. AI Scanner sells 4 in-app purchases, starting at $3.99 per month and Acid Interval sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Acid Interval holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: AI Scanner has 9.2K ratings behind it against 1, so its average is the more settled of the two.

AI Scanner ships an update every 8 days, Acid Interval every 2 weeks. Both last shipped on October 22, 2026.
