# Promptdex vs Threadmap

The clearest difference is update cadence: Promptdex at every 4 days against Threadmap's fortnightly. Promptdex also leads on iOS requirement (15.1 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Promptdex sells 3 in-app purchases, starting at $0.99 per 7 days and Threadmap sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Promptdex ships an update every 4 days, Threadmap fortnightly. Both last shipped on October 31, 2026.
