# HIIT vs SHRED

The clearest difference is in-app purchases: SHRED at none against HIIT's 11. SHRED also leads on ads (none vs shown) and rating (5.0 vs 4.8). HIIT's advantage is ratings volume (31K vs 6). On price, update cadence and device support there is nothing between them.

Both are free to download. HIIT sells 11 in-app purchases, starting at $2.99 per 7 days. SHRED asks for nothing beyond the download.

SHRED holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: HIIT has 31K ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 91% of HIIT's written reviews are positive against 100% of SHRED's.

HIIT ships an update monthly, SHRED every 3 weeks. The most recent releases landed on October 2, 2026 and September 20, 2026 respectively.
