# TrigIt vs Cartesian graph coordinates

The clearest difference is update cadence: Cartesian graph coordinates at every 4 days against TrigIt's every 4 months. Cartesian graph coordinates also leads on monetization model (free vs free with in-app purchases) and iOS requirement (12.0 vs 15.0). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. TrigIt sells 2 one-off in-app purchases and Cartesian graph coordinates sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

TrigIt ships an update every 4 months, Cartesian graph coordinates every 4 days. The most recent releases landed on October 10, 2026 and October 22, 2026 respectively.
