Gravitus vs JEFIT: The Strength Training Comparison (2026)
Updated September 15, 2026
JEFIT and Gravitus solve different problems. JEFIT has been running for well over a decade and carries the largest exercise library in the category, 1,400+ movements, with a long-running community of user-built routines and watch apps on both Apple Watch and WearOS. Gravitus is built around strength measurement: standards and a Strength Score calculated from 10M+ logged workouts by 300,000+ lifters, muscle engagement and exertion analysis, estimated 1RM trends, and published outcomes of +37 lb bench, +57 lb squat and +65 lb deadlift in a lifter's first year. JEFIT's free Basic plan includes the full exercise library and carries ads; Gravitus keeps core tracking free with no ads and puts the analytics suite and AI coaching in Pro.
| Feature | Gravitus | JEFIT | Bottom line |
|---|---|---|---|
| Exercise library | Deep coverage of barbell, dumbbell, machine and bodyweight work, with community videos on a lot of exercises | 1,400+ exercises, the largest library in this comparison | JEFIT. If you want an unusual movement already documented, it is there |
| Strength analytics | Muscle engagement analysis, exertion analysis, estimated 1RM trends, smart max and relative intensity guidance | Workout logs, progress charts, and record comparison with friends on Elite | Gravitus. This is the depth the app is built around |
| Strength standards | Standards and a Strength Score measured from 10M+ logged workouts, refreshed weekly | Not listed | Gravitus. It tells you where your lifts stand against real lifters |
| Published outcomes | +37 lb bench, +57 lb squat, +65 lb deadlift average first-year gains (men who trained the lift consistently for over a year on Gravitus) | No published outcome data | Gravitus is the only one of the two that publishes results |
| Ads | None | The free Basic plan carries ads | Gravitus. Nothing interrupts a set |
| Watch support | Full Apple Watch app: log sets and run rest timers from your wrist | Apple Watch and WearOS, with real-time sync and offline logging | JEFIT. It is one of the few apps covering both watch platforms |
| Community | Global feed defaulting to workout videos: form checks, PR attempts, real lifting | Community routines, and comparing records with friends on Elite | Gravitus for a feed you watch, JEFIT for a catalog of user-built routines |
| Programs and AI | AI workout generation, program library, custom templates | Program library with plans, and AI-guided routines that pick what you lift next | Tie. Both generate training and both ship a library |
| Rest timer | Yes, including from the wrist | Yes, automatic | Tie |
| Your data | Full workout export at gravitus.com/users/export/, plus CSV import at gravitus.com/workouts/import/ | Not listed | Gravitus. Your training history is portable on every account |
| Platforms | iPhone, Android, Apple Watch | iOS, Android, Apple Watch, WearOS | JEFIT adds WearOS. Both cover iPhone, Android and a watch |
| App Store rating | 4.8 | 4.76 across 46,886 US ratings | Close. JEFIT's count reflects a much older app |
"Not listed" means the feature does not appear in that app's own published materials as of September 2026. It does not mean the app cannot do it. Check the app's App Store listing or website for the current picture.
What is JEFIT genuinely best at?
The catalog. JEFIT's library covers 1,400+ exercises, which is the largest in this comparison, and it has had well over a decade to fill in the long tail. If you train on an unusual machine, or you program a variation that most apps have never heard of, JEFIT probably already has it with a demo attached. Behind that sits a community library of routines built by real users over the same period, which is a genuinely useful thing to browse when you want to see how other people structure a split.
JEFIT is also one of the few apps in the category with watch apps on both Apple Watch and WearOS, with real-time sync and offline logging. If you train with an Android phone and a WearOS watch, that combination is hard to find, and JEFIT has it.
One thing to know before you install it: the free Basic plan carries ads. JEFIT documents this itself. Elite removes them and adds premium programs and friend record comparison, sold monthly or annually; check the App Store listing for current pricing.
Where do your lifts actually stand?
A large exercise library tells you what you can do. It does not tell you how you are doing.
Gravitus maintains strength standards and a Strength Score measured from real logged workouts, refreshed weekly against 10M+ workouts from 300,000+ lifters, and we publish the methodology. The app can tell you where your squat sits among lifters at your bodyweight, what a realistic next number looks like, and which lifts are lagging the rest of your training. On top of that it analyzes muscle engagement across any timespan, tracks exertion, and projects estimated 1RM trends. Strength standards and percentile positioning do not appear in JEFIT's published materials as of September 2026.
What does a year on Gravitus look like?
Men who trained a lift consistently for over a year on Gravitus added these averages to their best lifts. We publish them because we think a tracker should be judged on what its users lift, not on its feature count.
Check your own numbers against real lifters on our strength standards pages.
Which app runs on your devices?
JEFIT runs on iOS, Android, Apple Watch and WearOS. Gravitus runs on iPhone, Android and Apple Watch, and the Android app has the same logging, PR tracking, programs and analytics as the iPhone app. If a WearOS watch is central to how you train, JEFIT covers a platform we do not. If you train from an iPhone, an Android phone or an Apple Watch, both apps cover you.
Can you take your training history with you?
Gravitus exports your complete workout history at gravitus.com/users/export/ on every account, with no Pro requirement, and imports workout history from a CSV file at gravitus.com/workouts/import/. A CSV export path does not appear in JEFIT's published materials as of September 2026, so check inside the app before you build years of history there. A tracker you cannot leave is a tracker that does not have to keep earning you.
