Where MyWorkoutCalendar Wins

Works on Android, web, and desktop

FitnessAI is iPhone-only. If you use Android, a Chromebook, or want to plan workouts on a laptop, MWC is the only option of the two.

Free tier without a trial

MWC offers AI workout generation without a paywall or 7-day trial countdown. FitnessAI requires entering payment info even for the trial.

Multi-week programs included

MWC includes 10+ proven programs (PPL, 5/3/1, Arnold Split, etc.) you can run for 4-12 weeks. FitnessAI focuses on single-session generation.

AI coach chat

Ask MWC to explain why a movement is in your plan, swap an exercise, or adapt for an injury. FitnessAI does not have conversational AI.

Where FitnessAI Wins

Trained on 5.9M+ real workouts

FitnessAI markets a large historical workout dataset. MWC uses GPT-4 with curated programming logic, not a proprietary dataset.

iPhone-native performance

If you exclusively use iOS, a native app has slight feel advantages over a PWA.

Built-in barbell weight progression

FitnessAI auto-progresses your top set weight session-over-session. MWC suggests progressions but does not auto-fill weights.
