Dr. Muscle and Trackist are both sold as an AI coach, and both take the programming off your hands. They differ on how often the plan moves, how much of the app you can see before paying, and by a factor of five on price.
The short answer
Dr. Muscle adapts at the level of the set, with periodisation and advanced techniques built in, and charges accordingly: $49.99 a month or $399.99 a year.
Trackist adapts at the level of the day, the week and the block, for $9.99 a month or $49.99 a year, with a usable free tier under it.
What Dr. Muscle does well
It has been doing automated progression for longer than most: the program updates after each completed set, it uses techniques like rest-pause and daily undulating periodisation, and it carries a large exercise library across gym, home and bodyweight training. There is a two-week trial with everything in it, and a chat where you can reach coaches and other users. It holds a 4.5 rating from a few hundred App Store ratings.
Where Trackist is different
The unit of the plan. Trackist writes a block of four to twelve weeks that you can see in full before you start it, with a deload in the last week when the block is long enough. Adjustments happen when there is something to react to — a report, a pain, the end of a block — not after every set.
What you can say to it. Too hard, too easy, or this hurts. The first report is noted; a repeat rewrites that day; a pattern across weeks rebuilds the block's remaining weeks. A pain report swaps the movement and stores the limitation on your profile.
The price, and the free tier. Trackist Pro is $9.99 a month or $49.99 a year, with the first seven days free. Free is not a demo: one plan for life, week one of every block, the editor, a substitute when something hurts, a restart, the block recap, the Strength Score and its chart, Strength Age, Momentum and every measurement.

Which one fits you
Dr. Muscle if you want the most aggressive automation available and the price is not the deciding factor.
Trackist if you want a coach that writes the block, reacts when you tell it something, and costs about a fifth as much. See what the free tier covers, or start from a known split.
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. There is a two-week trial with every feature in it.
Is Trackist an AI personal trainer too?
Yes. It writes your plan from your goal, experience, equipment, joint limitations, schedule and age, suggests the load for each exercise from your logs, rewrites a day or a block when you report a problem, and writes the next block from what the last one produced.
Which one is better value?
Trackist costs $9.99 a month or $49.99 a year against $49.99 a month or $399.99 a year, and it stays useful without paying: a full plan, week one of every block and every measurement are free. Whether the extra automation is worth the difference is your call.
Does Trackist adjust after every set?
No, and that is deliberate. The suggested load moves session to session from what you lifted and how hard it felt; the plan itself changes when you report a problem or when a block ends. A number that moves during a set has nothing left to say when the session is over.
