# Dual N vs Mind

The clearest difference is update cadence: Dual N at every 6 days against Mind's every 5 months. Mind's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 18.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Dual N sells 5 in-app purchases, starting at $1.99 per month and Mind sells 2 in-app purchases, starting at $29.99 per year. Whichever you choose, the download price is not the number that matters.

Dual N ships an update every 6 days, Mind every 5 months. The most recent releases landed on September 26, 2026 and October 16, 2026 respectively.
