Comparison
Fitbod builds each workout with its own algorithm, using your logged training and a muscle recovery estimate. It is mature, focused on training, and has a large video library. Apex Stacked builds a training week on your phone with Apex Pro, at a lower price, and keeps food, sleep, bloodwork and protocol tracking in the same app. If you only want adaptive workouts, Fitbod is a strong pick. If you want lower cost or your health numbers next to your training, Apex Stacked may fit better.

Things Apex Stacked does not do. It has no web app, no iPad support, no light theme and no meal photo recognition. There is no free training plan. Free plan limits are 4 saved workouts, 1 active protocol, 10 favorite foods and 7 custom exercises.
Apex Stacked can read a CSV export from another app, or a workout you paste in. It shows you what it read, and you review it before saving. We have not confirmed that Fitbod's export format works, so check the review screen carefully.
If a lift comes in with an unusual name, link it to an exercise in the library so your volume and PRs stay together. Then set up your gym's equipment, pick a split and schedule, and, with Apex Pro, build your first week. More on planning: Training plans.
