Short answer: Choose Forma if you want a coach you can chat with that also sees your food log, and can read a nutrition label from a photo. Choose Fitbod for generated workouts, Alpha Progression for set-by-set weight targets, Zing for form feedback, Freeletics for bodyweight coaching, Caliber to connect your data to ChatGPT or Claude, and Hevy to build plans in ChatGPT.
