# Trendio vs Weight

The clearest difference is device support: Trendio at 3 against Weight's 1. Trendio also leads on iOS requirement (15.1 vs 17.0). On price, update cadence, ads and in-app purchases there is nothing between them.

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