# HTRS vs ISTH 2026

The clearest difference is device support: ISTH 2026 at 3 against HTRS's 1. ISTH 2026 also leads on iOS requirement (14.0 vs 16.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
