# HIIT vs ThinkFIT

The clearest difference is rating: HIIT at 4.8 against ThinkFIT's 3.7. HIIT also leads on review sentiment (91% vs 50%) and ratings volume (31K vs 3). ThinkFIT's advantage is in-app purchases (none vs 11) and ads (none vs shown). On price 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. ThinkFIT asks for nothing beyond the download.

HIIT holds the better App Store score, 4.8 against 3.7.
