Dr. Muscle vs Dr. Muscle X: What's the Difference?
Same account, two apps. Classic has everything. X is faster. You choose.
Key Takeaways
- One account. Two apps. Same login, same data. Your existing subscription covers both.
- Classic app runs on iOS and Android. Dr. Muscle X runs on the web at x.dr-muscle.com.
- X is faster with a modern interface but does not have all features yet. Classic has the full 27+ smart feature set.
If you heard about Dr. Muscle X and wondered how it relates to the app you already use, here is the short answer: they are two versions of the same product. Your account, history, and subscription work in both. You can switch between them anytime.
One Account, Two Apps
Dr. Muscle X is the future of the app, rebuilt from the ground up with a faster engine and cleaner interface. It may eventually replace the classic version, but for now both run side by side. Think of it as one AI system with two doors.
Dr. Muscle (Classic)
The mobile app you download from the App Store or Google Play. It has every feature we have built over the past decade: progressive overload automation, rest-pause sets, drop sets, deloads, daily undulating periodization, challenge mode, and more. If you need the full toolkit, use classic.
Dr. Muscle X (Early Access)
A web app at x.dr-muscle.com. It loads faster, feels smoother, and shows your all-time records and reps in reserve during sets. Right now it focuses on the core workout loop. More features will roll out over time.

| Classic | X | |
|---|---|---|
| Platform | iOS, Android | Web (installable) |
| Features | Full (27+) | Core workout loop |
| Speed | Standard | Faster |
| Best for | AI coaching | Daily training |
Which Should I Use?
Use classic for world-class AI coaching. It has everything. Try X if you want to experience the same great training programs in a faster and more modern interface, but you can live with limited features outside of workouts for now. Your data syncs between both, so you lose nothing by switching back and forth.
