Strongineering vs Gravl
Gravl plans each gym workout and tells you the next weight. Strongineering plans whole training phases, adjusts with RPE and readiness, and sets your warm-ups from a movement assessment.
The short answer.
Choose Strongineering if…
- You want periodized phases rather than workout-by-workout planning.
- You want HRV, sleep, and resting heart rate from Apple Health to inform a readiness check.
- You train for races or hybrid goals too.
- You want a lifetime purchase option.
Choose Gravl if…
- You need Apple Watch, Wear OS, Garmin, or Android support.
- You want an AI form checker.
- You like rating sets Easy or Hard instead of using RPE.
- You want to try it free before subscribing.

Key differences.
Phases vs next workout
Gravl decides the next session. Strongineering sets a phased plan (building, strength, peaking) so each week has a purpose.
RPE vs three buttons
Gravl asks if a set was easy, ideal, or hard. Strongineering uses the full RPE scale to set the next load and reps.
Analytics beyond one score
Gravl rates you with a Strength Score against bodyweight standards. Strongineering tracks estimated 1RM, a Strength Index, weekly volume vs MEV/MRV, and a muscle recovery map.
