Verdict
The clearest difference is monetization model: Workout Trainer AI at free with in-app purchases against HIIT | Down Dog's subscription. HIIT | Down Dog's advantage is ads (none vs shown) and update cadence (every 2 weeks vs monthly). On price, rating, review sentiment 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. Workout Trainer AI sells 11 in-app purchases, starting at $6.99 per month and HIIT | Down Dog sells 5 in-app purchases, starting at $12.99 per month. Whichever you choose, the download price is not the number that matters.
