If you're a coach or someone training on your own, you've probably run into this: one app for training programs, another for nutrition, a third for logging sets and weight, and a separate messenger to talk to your coach or clients. Each tool does its own slice well, but nothing talks to anything else — data doesn't sync, and a coach ends up manually piecing together a client's progress by hand.
We put together an honest comparison of Hartlab against four tools that most often end up in that pile: Trainerize (coach CRM), MyFitnessPal (nutrition), and Hevy/Strong (workout tracking).

Trainerize is one of the most popular coach tools: program assignment, client chat, basic tracking. But it's purely a coach-side CRM — the athlete gets an app with no AI plan generation, and nutrition is only partially supported. A coach who wants the full loop (training + nutrition + AI) ends up buying another tool on top.
MyFitnessPal is the standard for calorie/macro tracking, with a huge food database. But it's a solo app: no training, no coach connection, no program logic at all. It works as an add-on to something else, not as a standalone solution.
Hevy and Strong are favorites for people who just want to log sets/reps/weight with minimal friction. That's their strength — and their ceiling: no nutrition, no coach, no AI, no web version.
Hartlab is the only tool on this list where the coach and the athlete work inside the same product: the coach assigns a program (manually or via AI generation), the athlete logs workouts and meals, both see progress and chat — without switching between four apps. For someone training solo (no coach), the same AI generates a personal training and nutrition plan from scratch.
Can I use Hartlab without a coach?
Yes — the "User" role exists exactly for solo training: AI generates a training and nutrition plan with no need to hire a coach.
Is Hartlab free for an athlete managed by a coach?
Always. An athlete under a coach never pays Hartlab directly — Pro capabilities unlock automatically once the coach is on a Pro plan.
How is Hartlab different from just combining Trainerize + MyFitnessPal + Hevy?
One login, shared data between coach and athlete, and AI plan generation — none of the tools above do that.
