Gravitus vs Strong: The Strength Training Comparison (2026)

By Bryan Alger, Co-Founder of Gravitus

Updated September 15, 2026

Gravitus and Strong are both built for barbell training, and they optimize for different things. Strong optimizes for speed: it is the fastest app in the category for recording a set and getting back under the bar, and its 4.9 rating across roughly 108,000 US App Store ratings is the largest in the category. Gravitus optimizes for knowing where you stand: strength standards and a Strength Score measured from 10M+ logged workouts by 300,000+ lifters, muscle engagement and exertion analysis, estimated 1RM trends, and published outcomes. Lifters who train a lift consistently for a year on Gravitus add an average of 37 lb to bench, 57 lb to squat, and 65 lb to deadlift. Gravitus runs on iPhone, Android and Apple Watch.
Feature Gravitus Strong Bottom line
Logging speed Fast logger tuned for barbell work, with set targeting that follows the set you tapped The fastest logger in the category, and it has the reputation to prove it Strong. This is what it is built for and it wins on it
Strength analytics Muscle engagement analysis, exertion analysis, estimated 1RM trends, smart max and relative intensity guidance Progress charts and records per exercise 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, not just whether they moved
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
Barbell tooling Plate calculator, rep max tools, PR detection matched to each exercise type Plate calculator, RPE, supersets, customizable rest timer Both handle the barbell properly. Gravitus adds PR detection that knows the exercise type
Apple Watch Full Watch app: log sets and run rest timers from your wrist Full Watch app: log sets from your wrist Comparable Watch apps
Community Global feed defaulting to workout videos: form checks, PR attempts, real lifting Workout sharing Gravitus. The feed is video-first and community videos cover a lot of exercises
Programs and AI AI workout generation, program library, custom templates Custom routines, capped at three on the free tier Gravitus. Strong builds routines, it does not generate them for you
Your data Full workout export at gravitus.com/users/export/, plus CSV import at gravitus.com/workouts/import/ CSV export Both give your history back. Gravitus also takes a CSV in
Platforms iPhone, Android, Apple Watch iPhone, iPad, Android, Apple Watch Close. Strong adds iPad, Gravitus adds a lifting feed on every platform
App Store rating 4.8 4.9 across roughly 108,000 US ratings Strong. It has been collecting ratings since 2011 and the score is earned

"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 Strong genuinely best at?

Strong is the fastest way to record a set that exists on a phone, and we are not going to pretend otherwise. Open it, tap, the set is logged, the rest timer starts, and you are back under the bar. If you already know your program cold and you want the app to stay out of the way, that is a real advantage that no feature list beats. Strong also covers the barbell fundamentals properly: a plate calculator, RPE, supersets, a customizable rest timer, a full Apple Watch app, and CSV export whenever you want your history back. Its App Store rating is 4.9 across roughly 108,000 US ratings (Apple, September 2026), which is the largest rating count of any dedicated strength logger, and a number that size is not an accident.

Gravitus is fast too, and set targeting follows the set you actually tapped so mid-workout edits do not cost you taps. But speed is where Strong's ambition ends, and it is where ours starts.

Where do your lifts actually stand?

Strong stores your training history. Gravitus reads it.

Gravitus maintains strength standards and a Strength Score measured from real logged workouts, refreshed weekly against a dataset of 10M+ workouts from 300,000+ lifters. That means the app can tell you where your squat sits among lifters at your bodyweight, not just that it went up 10 lb since April. We publish how we calculate it, including the estimator and the outlier rules, because a number you cannot check is a number you should not trust.

On top of that, Gravitus analyzes muscle engagement across any timespan, tracks exertion, projects estimated 1RM trends, and gives you smart max and relative intensity guidance that answers "what should I be able to do today?". Strong's published materials do not describe strength standards or percentile positioning.

What does a year on Gravitus look like?

We publish our outcomes. Men who trained a lift consistently for over a year on Gravitus added these averages to their best lifts.

+37 lb
Bench
+57 lb
Squat
+65 lb
Deadlift

Strong publishes no outcome data. That is not a criticism of the app, it is a difference in what the two companies are willing to put on the record.

Which app runs on your devices?

Strong runs on iPhone, iPad, Android and Apple Watch. 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. Both give you a real Watch app that logs sets from your wrist, so if the watch is how you train, either one works.

If you want a browser-based logger, neither app is your answer. Hevy has a web app and we say so on our comparison with them.

Can you bring your Strong history with you?

Strong exports your workout history to CSV. Gravitus imports workout history from a CSV file at gravitus.com/workouts/import/, and your Gravitus history is exportable from day one at gravitus.com/users/export/ on every account, with no Pro requirement. Your trends, estimates and standards calibrate within your first few sessions either way.

Frequently Asked Questions

It depends on what you want the app to do. Strong is better at recording a set quickly, and it is the fastest logger in the category. Gravitus is better at telling you what your training means: muscle engagement and exertion analysis, estimated 1RM trends, strength standards and a Strength Score measured from 10M+ logged workouts, and published first-year outcomes of +37 lb bench, +57 lb squat and +65 lb deadlift. If you want a log, take Strong. If you want to know how strong you are, take Gravitus.

Speed and simplicity. Strong records a set in fewer taps than anything else in the category, and that matters when you are resting 90 seconds between heavy sets. It also has the largest rating count of any dedicated strength logger, 4.9 across roughly 108,000 US App Store ratings as of September 2026, and it runs on iPad, which Gravitus does not.

Yes. Gravitus publishes strength standards and a Strength Score measured from real logged workouts, refreshed weekly against 10M+ workouts from 300,000+ lifters, with the methodology published at gravitus.com/strength-standards/methodology/. Strength standards do not appear in Strong's published materials as of September 2026.

Yes to both. Gravitus runs on iPhone, Android and Apple Watch. The Android app has the same logging, PR tracking, programs and analytics as the iPhone app, and the Watch app logs sets and runs rest timers from your wrist. Strong also covers iPhone, iPad, Android and Apple Watch.

Strong exports your history to CSV, and Gravitus imports workout history from a CSV file at gravitus.com/workouts/import/. Your Gravitus history stays exportable from day one at gravitus.com/users/export/ on every account, with no Pro requirement, and your trends, estimates and standards calibrate within your first few sessions.
