Trackist vs Dr. Muscle compares 2 apps sold as an AI coach. Both take the programming off your hands. Trackist writes a plan for the next 4 to 12 weeks from 14 questions, suggests today’s weight, and rewrites the plan when a problem you report comes back in a later week. The 2 differ in how often the plan changes and in how much of it you can see ahead.
Which one should you pick?
Dr. Muscle adjusts set by set, with periodization and advanced techniques built in. It costs $49.99 a month or $399.99 a year.
Trackist adjusts by the day, the week and the plan, and writes all 4 to 12 weeks up front.
What Dr. Muscle does well
Dr. Muscle has done automatic progression for longer than most. The program updates after each set you finish. It uses techniques like rest-pause sets and daily undulating periodization, where the reps and weight change from one session to the next. Its exercise library is large and covers gym, home and bodyweight training. The Dr. Muscle 2-week trial includes everything. After the trial, Dr. Muscle gives one exercise recommendation a day at no cost. A chat lets you reach coaches and other users. It has a 4.5 rating from a few hundred App Store ratings.
Where Trackist is different
The plan runs 4 to 12 weeks
Trackist writes a plan for 4 to 12 weeks. In a plan of 6 weeks or more, the last week is a deload, a lighter week to recover. The whole plan is written up front: one training week, repeated for the plan's length. The plan changes when there is something to react to: a report repeated in a later week, a pain or the end of the plan. It does not change after every set.
You can tell it what went wrong
Say a session was too hard, too easy, or that something hurts. The first report is noted. If it comes back in a later week, Trackist rewrites that day or rebuilds the rest of the plan. A pain report swaps the exercise and stores the limitation on your profile.
A bad night makes the day lighter
Before the first set, Trackist asks how you slept, how sore you are and how much energy you have. With Apple Health connected, the sleep answer starts from last night. After a poor night, low energy or soreness in the half of the body you train today, it offers a lighter session: one set fewer on each strength exercise that has more than one, 30 seconds more rest and no finisher, at the same weights. It changes today only.

FAQ
Questions, answered.
How much does Dr. Muscle cost?
The App Store listed Dr. Muscle at $49.99 a month and $399.99 a year in September 2026, with a meal plan add-on at $18.99 a month. The 2-week trial includes every feature.
Is Trackist an AI personal trainer too?
Yes. It writes your plan from 14 questions about your goal, experience, equipment, joints, schedule, session length and age, and suggests your next weight from the sets you logged. It rewrites a day or the rest of the plan when a problem you reported comes back in a later week, and writes the next plan from what the last one produced.
Can Trackist plan around a joint that hurts?
Yes. One of the 14 questions is about your joints, and the plan works around a joint by direction: a shoulder that hurts when pressing still gets rows and pulldowns. If something starts to hurt later, name the exercise, the joint and how bad it is, and you get a swap that usually trains the same muscle. Trackist keeps the limitation on your profile. It changes the exercise. Diagnosis and treatment belong to a physio or a doctor.
Does Trackist adjust after every set?
No, on purpose. The suggested weight moves from session to session, from what you lifted and how hard it felt. The plan itself changes when a problem you report comes back in a later week, or when a plan ends. After a poor night, low energy or soreness, Trackist offers a lighter session for that day at the same weights.
