# Calculator vs Helm

The clearest difference is device support: Calculator at 3 against Helm's 1. On price, update cadence, ads and in-app purchases there is nothing between them.

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

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 10, 2026 and October 3, 2026 respectively.
