Bottom line: Hevy is the best overall workout tracking app for most lifters — it combines a generous free tier with excellent logging, social features, and clean design. Strong is the best for Apple Watch users who want seamless wrist-based logging. Fitbod is the pick if you want AI-generated workouts instead of tracking your own programming. Your choice depends on whether you want to log, be coached, or analyze.
How We Evaluate
We do not claim to have run months of programming inside every app on this list. This ranking is built from hands-off sources: current feature documentation and pricing from each developer, the app-store changelogs that show how actively each one is maintained, and a large body of user reviews — weighted toward long-term users rather than first-week impressions, since logging apps live or die on whether people are still using them a year in. We weigh exercise-library completeness, logging speed during a working set, programming flexibility, data export, and what the free tier actually includes. Feature claims are taken from the developer; everything else is our judgement or aggregated user consensus.
The fitness app market is crowded with options that look good in screenshots but fall apart during a real training session. A workout logger needs to be fast enough that you can update it between sets without losing your rest period to tapping and scrolling. Every app on this list passed that basic test.
1. Hevy — Best Overall Workout Tracker
Hevy has earned its reputation as the most popular workout logger for a reason. The free tier gives you unlimited workout logging with a 300-plus exercise library, custom exercise creation, rest timers, and personal record tracking. The social feed adds an accountability layer that most competitors lack — seeing your training partners log their sessions is surprisingly motivating.
The interface is clean and fast. Logging a set takes two taps — enter weight, enter reps, done. You can duplicate previous workouts with one tap and adjust numbers from there, which makes progressive overload tracking effortless. The routine system lets you save templates and reuse them, though the free tier limits you to three saved routines.
Hevy Pro unlocks unlimited routines, advanced analytics with muscle group heatmaps, and body measurement tracking for $4.17 per month on the annual plan. Worth it for serious lifters; unnecessary for casual gym-goers. Read our full Hevy review for the complete breakdown.
Best for: Lifters who want a free, full-featured logger with social accountability.
Price: Free (Pro: $49.99/year)
2. Strong — Best for Apple Watch
Strong has been around longer than most competitors, and its maturity shows in the polish. The Apple Watch app is the best in the category — you can log full sets directly from your wrist without pulling out your phone, which is a genuine quality-of-life improvement when you are in the middle of a set of heavy deadlifts and your phone is across the gym.
The logging experience is slightly more structured than Hevy. Strong emphasizes workout templates and guides you through your planned session exercise by exercise, which some lifters prefer over Hevy’s more freeform approach. The progress charts are clear and useful, showing volume and estimated one-rep max trends over time.
Strong’s free tier is more limited than Hevy’s — you get fewer saved routines and the exercise library is smaller. The Pro upgrade is comparable in price. For a detailed head-to-head, see our Strong vs Hevy comparison. Read the full Strong review for more.
Best for: Apple Watch users who want seamless wrist logging.
Price: Free (Pro: $4.99/month or $29.99/year)
3. Fitbod — Best AI-Generated Workouts
Fitbod takes a fundamentally different approach. Instead of logging your own programming, Fitbod generates workouts for you based on your training history, available equipment, muscle recovery status, and goals. Each session is algorithmically balanced to train fresh muscle groups while giving fatigued ones time to recover.
This is ideal for intermediate lifters who have outgrown beginner programs but do not want to invest the time to learn programming. The AI does a genuinely good job of varying exercises and managing volume across training days. It also adapts to the equipment you have, which makes it excellent for home gym users with limited gear.
The downside is cost — Fitbod requires a subscription at $12.99 per month with no meaningful free tier. And if you follow a specific program from a coach or a structured plan like 5/3/1 or GZCL, Fitbod’s AI-generated workouts are not what you need. This is a tool for people who want to show up and be told what to do.
Best for: Lifters who want AI-programmed workouts rather than tracking their own plan.
Price: $12.99/month or $79.99/year
4. JEFIT — Best for Bodybuilding
JEFIT has been a staple in the bodybuilding community for over a decade. Its exercise database is massive — over 1,400 exercises with HD video demonstrations. The workout planner is highly detailed, allowing you to program specific set structures like drop sets, supersets, and pyramid sets that other apps handle clumsily or not at all.
The body measurement and progress photo features are more developed than in any other app on this list. If you track arm circumference, waist measurements, and monthly physique photos alongside your training data, JEFIT keeps everything in one place. The community aspect includes pre-built routines from other users that you can import and modify.
The interface feels dated compared to Hevy and Strong, and the app can be slow to load on older devices. But for pure bodybuilding-style training with detailed exercise programming, JEFIT remains hard to beat.
Best for: Bodybuilders who need detailed exercise programming and body tracking.
Price: Free (Elite: $6.99/month or $39.99/year)
5. Strava — Best for Hybrid Athletes
If your training includes both lifting and endurance work, Strava is worth mentioning even though it is primarily a running and cycling app. Strava’s strength is GPS-based activity tracking — run tracking, route mapping, segment leaderboards, and social features built around endurance performance.
For pure strength training, Strava is not competitive with Hevy or Strong. But if you run three days a week and lift three days a week, Strava handles the running side better than any lifting app handles the endurance side. Some hybrid athletes use Strava for cardio and Hevy for lifting, which is a reasonable combination. See our Strava vs Garmin Connect comparison for how it stacks up against watch-based tracking.
Best for: Runners and cyclists who also lift.
Price: Free (Summit: $11.99/month or $79.99/year)
How to Choose the Right App
The decision tree is simpler than it looks. If you want to log your own workouts with a clean, modern interface, start with Hevy — it is free, full-featured, and the social layer adds motivation that pure loggers lack. If you own an Apple Watch and want to log from your wrist, Strong has the best watch integration. If you want someone (or something) to tell you what to do each session, Fitbod’s AI is the best option.
If you train with a combination of lifting and cardio, pair a strength logger with a dedicated endurance tracker like Strava or your Garmin watch. And if you want to track nutrition alongside your training, a food logger like Cronometer or MyFitnessPal fills a completely different role — see our best nutrition tracking app roundup for those options.
The most important thing is picking one app and actually using it consistently. A month of logged workouts in any of these apps gives you more actionable data about your training than a year of guessing. Start with a free option, build the habit, and upgrade only when you hit a genuine limitation.
The Gear Behind Better Tracking
The best workout tracker is the one you feed good data. For lifters that means a dumbbell set that lets you progress in small steps \u2014 see our tested dumbbell picks. For runners, a chest strap fixes heart rate accuracy for any app.

Frequently Asked Questions
What is the best free workout tracking app?
Hevy. Its free tier includes unlimited workout logging, 300-plus exercises, social features, and basic progress tracking. Most lifters will never hit a limitation that requires upgrading to the paid version.
Do I need a paid workout app?
No. Both Hevy and Strong offer generous free tiers that cover the essentials. Paid upgrades add convenience and analytics, but the core logging functionality is free. The only exception is Fitbod, which requires a subscription to be useful at all.
Can I switch apps without losing my data?
Most apps offer CSV export, and some support direct import from competitors. Hevy Pro includes CSV export. Strong allows export as well. If switching, export your history first and check whether your new app can import it before deleting anything.
Should I use my smartwatch or a phone app to track workouts?
Phone apps offer better logging detail and larger screens for reviewing workout history. Smartwatch apps are faster for logging between sets since you do not need to pick up your phone. The ideal setup is an app that syncs between both — Strong and Hevy both offer this. For help choosing a watch, see our best smartwatch and best fitness tracker guides.
Is a workout app better than a spreadsheet?
For most people, yes. Apps give you exercise libraries, automatic PR tracking, rest timers, and progress charts with zero setup. Spreadsheets offer unlimited flexibility but require manual configuration. The only people who should prefer spreadsheets are those who need highly custom calculated fields or who already have years of data in Google Sheets they do not want to migrate.
