Verdict
The clearest difference is ads: Phyzseek at none against HIIT's shown. HIIT's advantage is rating (4.8 vs 4.4) and ratings volume (31K vs 87). On price, review sentiment, update cadence and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. HIIT sells 10 in-app purchases, starting at $2.99 per 7 days and Phyzseek sells 3 in-app purchases, starting at $12.99 per month. Whichever you choose, the download price is not the number that matters.
HIIT holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: HIIT has 31K ratings behind it against 87, 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 84% of Phyzseek's.
Both ship on a similar rhythm, roughly monthly. The most recent releases landed on November 7, 2026 and November 6, 2026 respectively.
