# BigPlan vs KnowTree

The clearest difference is ads: BigPlan at none against KnowTree's shown. KnowTree's advantage is update cadence (every 9 days vs every 3 weeks) and iOS requirement (15.1 vs 18.5). On price, in-app purchases and device support there is nothing between them.

Both are free to download. BigPlan sells 1 one-off in-app purchase and KnowTree sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

BigPlan ships an update every 3 weeks, KnowTree every 9 days. The most recent releases landed on October 15, 2026 and September 24, 2026 respectively.
