# Simpler vs Uknow.AI

The clearest difference is ads: Simpler at none against Uknow.AI's shown. Simpler also leads on rating (4.8 vs 4.6) and review sentiment (90% vs 78%). Uknow.AI's advantage is update cadence (weekly vs every 2 weeks) and iOS requirement (13.0 vs 15.6). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. Simpler sells 10 in-app purchases, starting at $7.99 per 7 days and Uknow.AI sells 10 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.
