# OneTodo vs KyPDF

The clearest difference is monetization model: KyPDF at freemium against OneTodo's subscription. KyPDF also leads on review sentiment (100% vs 71%) and update cadence (every 4 days vs every 9 days). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. OneTodo sells 3 in-app purchases, starting at $0.99 per month and KyPDF sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

OneTodo ships an update every 9 days, KyPDF every 4 days. The most recent releases landed on October 29, 2026 and October 31, 2026 respectively.
