# PMDD Tracker vs zday

The clearest difference is device support: PMDD Tracker at 3 against zday's 1. PMDD Tracker also leads on iOS requirement (13.0 vs 26.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. PMDD Tracker sells 2 in-app purchases, starting at $9.99 per month and zday sells 4 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
