# Able Brain Exercises vs NNAT

The clearest difference is update cadence: NNAT at every 2 weeks against Able Brain Exercises's every 29 months. Able Brain Exercises's advantage is iOS requirement (9.0 vs 13.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Able Brain Exercises sells 3 one-off in-app purchases and NNAT sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Able Brain Exercises ships an update every 29 months, NNAT every 2 weeks. The most recent releases landed on October 6, 2026 and October 1, 2026 respectively.
