# Genius vs Prismo

The clearest difference is ads: Genius at none against Prismo's shown. Prismo's advantage is update cadence (every 4 days vs every 2 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Genius sells 11 in-app purchases, starting at $3.99 per month and Prismo sells 4 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Genius ships an update every 2 months, Prismo every 4 days. The most recent releases landed on October 24, 2026 and October 7, 2026 respectively.
