# Neural Network vs SpellInterview

The clearest difference is update cadence: SpellInterview at every 5 days against Neural Network's every 3 weeks. Neural Network's advantage is device support (4 vs 1) and iOS requirement (15.6 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Neural Network sells 3 in-app purchases, starting at $12.99 per 6 months and SpellInterview sells 2 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Neural Network ships an update every 3 weeks, SpellInterview every 5 days. The most recent releases landed on October 8, 2026 and October 9, 2026 respectively.
