# Right Triangle vs Bend Calculator

The clearest difference is update cadence: Bend Calculator at every 4 days against Right Triangle's every 3 weeks. Right Triangle's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Right Triangle sells 8 one-off in-app purchases and Bend Calculator sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Right Triangle ships an update every 3 weeks, Bend Calculator every 4 days. The most recent releases landed on November 7, 2026 and November 6, 2026 respectively.
