# N vs RecallKit

The clearest difference is ads: N at none against RecallKit's shown. N also leads on ratings volume (240 vs 1). RecallKit's advantage is rating (5.0 vs 4.7) and update cadence (every 2 weeks vs monthly). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. N sells 6 in-app purchases, starting at $8.99 per month and RecallKit sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

RecallKit holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: N has 240 ratings behind it against 1, so its average is the more settled of the two.

N ships an update monthly, RecallKit every 2 weeks. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
