# BTS vs ChartMath

The clearest difference is ads: ChartMath at none against BTS's shown. BTS's advantage is update cadence (every 2 days vs weekly) and iOS requirement (13.0 vs 15.1). On price, in-app purchases and device support there is nothing between them.

Both are free to download. BTS sells 1 in-app purchase, starting at $199.00 per year and ChartMath sells 1 in-app purchase, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

BTS ships an update every 2 days, ChartMath weekly. The most recent releases landed on September 10, 2026 and September 21, 2026 respectively.
