# QuickNote.AI vs Stealth AI

The clearest difference is rating: QuickNote.AI at 5.0 against Stealth AI's 4.5. QuickNote.AI also leads on ads (none vs shown) and update cadence (every 3 days vs every 2 weeks). Stealth AI's advantage is ratings volume (474 vs 1) and device support (3 vs 1). On price, in-app purchases and monetization model there is nothing between them.

Both are free to download. QuickNote.AI sells 1 in-app purchase, starting at $2.99 per 7 days and Stealth AI sells 14 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.

QuickNote.AI holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Stealth AI has 474 ratings behind it against 1, so its average is the more settled of the two.
