Best Workout App in 2026: Gainr vs Strong vs JEFIT vs Hevy vs Fitbod

Finding the right workout app shouldn't feel like a workout itself. With hundreds of fitness apps on the App Store and Google Play, choosing one that actually helps you get stronger is overwhelming. We compared the most popular workout tracking apps side by side so you don't have to.

Whether you're looking for the best free workout app, an AI-powered coach, or simply a clean way to log your sets, this comparison breaks down what matters: features, pricing, AI and planning, and who each app is actually built for.

Competitor details are current as of October 2026. We checked every competitor price and feature against each company's own website, help pages, or US App Store listing (sources at the end). Prices are US prices and can vary by region. Gainr is our app, so weigh our perspective accordingly.

Quick Comparison: Top Workout Apps at a Glance

What We Looked For

Every lifter has different priorities. Some want a dead-simple rep counter. Others want an AI coach that adapts to their equipment, goals, and experience level. We looked at each app across six criteria:

1. Ease of use - How fast can you start logging?
2. AI and personalization - Does the app adapt to you?
3. Tracking depth - Sets, reps, PRs, volume, progression
4. Program support - Can you follow structured programs?
5. Free tier value - What do you actually get for free?
6. Devices - Phone, watch, and browser support

Gainr - Best for an AI-Planned Training Week

Best for: Lifters who want an AI coach to plan their week around their schedule and equipment, with free workout logging.

Gainr takes a different approach from most workout trackers. Instead of dropping you into an empty logbook, it asks about your goals, experience, schedule, and available equipment, then builds a weekly Coach plan you can follow and adjust.

What Sets Gainr Apart

Weekly Coach plans. Coach builds your training week from your goal, the days you can train, session length, equipment, and recent workouts. When the week changes, you can refresh it, move or swap sessions, skip a day, or ask the coach in chat to adjust it.

AI workout and program generation. You can also generate one-off workouts or full programs. Programs run 4, 8, or 12 weeks at 3 to 6 sessions per week, with push/pull/legs, upper/lower, full body, or bro split options.

Automatic PR tracking. For exercises logged with weight and reps, Gainr detects four types of personal records as you log sets. Reps-only and timed exercises have records suited to their logging mode.

• Heaviest Set (weight x reps volume)
• Heaviest Weight (absolute max)
• Most Reps (endurance milestone)
• Session Volume (total work in one session)

When you set a record, Gainr notifies you so you can see the progress.

Exercise history. Your last weight is visible mid-workout, and your full history for that exercise is a tap away.

Form demos. Tap How to during a workout to see start and finish photos, numbered steps, and the muscles the exercise targets. When an exercise has no demo yet, Gainr links to YouTube instead.

Apple Watch app. Log sets from your wrist, get rest alerts, and see live heart rate and calories. Watch workouts are saved to Apple Health, and finished workouts and new PRs can be shared as cards that include your heart rate and calories.

Training balance insights. The progress tab analyzes your muscle group distribution over 30 and 90-day windows, flags neglected muscle groups, and gives you a training balance score.

Gainr Pricing

Gainr's free tier includes the exercise library, unlimited workout logging, personal records, progress charts, and a one-time 14-day Coach preview. It allows 2 saved custom workouts/programs combined and 2 AI workout/program generation credits. Pro continues Coach access and removes workout and program creation limits. Pro costs $3.99/month or $29.99/year in the US; the app shows current pricing for your region.

Gainr Drawbacks

• No social features.
• No Wear OS app; the watch app is Apple Watch only.
• No data export yet.
• Phone and Apple Watch apps only; Pro can't be purchased on the web.

Strong - Best for Simple Logging

Best for: Experienced lifters who know their routine and want fast, no-frills set logging.

Strong has been a staple in the lifting community for years. The interface is clean, logging is fast, and it stays out of your way. If you already know exactly what you're doing in the gym and just need something to track it, Strong delivers.

Strengths

• Fast logging. Supersets, custom exercises, a warm-up calculator, custom timers, and Siri Shortcuts.
• Apple Watch app. A fully featured watch app that can log workouts with or without your iPhone.
• Apple Health and body measurements. Built-in measurements tracking with Apple Health support.
• CSV export. Export your workouts and measurements to CSV.

Weaknesses

• No AI features. Strong doesn't generate workouts or plans. You bring the plan; it tracks it.
• No built-in programs. You write your own routines.
• Free routine limit. The free version saves unlimited workouts but is limited to 3 custom routines.

Strong Pricing

Free with a 3-routine limit. Strong PRO is $4.99/month or $29.99/year, and the App Store also lists a lifetime option.

JEFIT - Best Exercise Database

Best for: Lifters who want a huge exercise library, expert-designed plans, and a community.

JEFIT has been around since the early days of fitness apps and has one of the largest exercise databases available, with HD video instructions and animations.

Strengths

• Large exercise library. 1,400+ exercises with video instructions and animations.
• AI Adaptive Plan. A personalized plan built around your goal, level, and equipment, plus suggested weights and reps from your past logs (Elite).
• Community. Members, group chats, contests, and leaderboards.
• Body measurements. Track body weight, body fat, and measurements.
• Watch and web. Apple Watch and Wear OS apps, plus web access.

Weaknesses

• Key features need Elite. The Adaptive Plan and an ad-free experience are Elite features. Free users can try the Adaptive Plan with a 7-day trial.
• Higher price. Elite costs more than Strong, Hevy, or Gainr.
• Lots of options. The large feature set can take time to learn.

JEFIT Pricing

Free Basic plan. Elite is $12.99/month or $69.99/year.

Hevy - Best for Social Lifters

Best for: Lifters who want to share workouts, follow friends, and stay motivated through community.

Hevy has grown quickly, and says it has more than 17 million users. If accountability through friends keeps you going to the gym, its feed-based approach makes it easy to share and compare workouts.

Strengths

• Social feed. Follow friends and athletes, see their workouts, and compare lifts.
• Low price. Pro is $2.99/month, with yearly and lifetime options.
• Hevy Trainer (Pro). Builds a program from your experience, goal, and equipment. Hevy describes it as an algorithm rather than AI.
• Everywhere you train. iOS, Android, Apple Watch, Wear OS, and web, with offline workouts and CSV export.

Weaknesses

• No built-in AI coach. You can send workouts to ChatGPT or Claude, but there's no coach inside the app.
• Free plan limits. Free users get 4 routines, 7 custom exercises, and graphs for the last 3 months.
• Best with friends. The social features matter most if people you know use Hevy too.

Hevy Pricing

Free with limits. Pro is $2.99/month, $23.99/year, or $74.99 lifetime.

Fitbod - Best Algorithm-Based App

Best for: People who want the app to decide their workout each day without thinking about programming.

Fitbod takes a different approach: instead of following a set routine, its algorithm recommends each workout based on your training history, muscle recovery, and available equipment.

Strengths

• Hands-off workouts. Open the app and get a workout. No planning required.
• Recovery-aware. Uses your history and recovery to choose which muscles to train.
• Equipment settings. Train with bodyweight, bands, or limited gear.
• Watch apps and offline use. Apple Watch and Wear OS companion apps, and generated workouts can be completed offline.
• Large library. Over 1,000 exercises with video demos.

Weaknesses

• Expensive. At $15.99/month or $95.99/year, it's the priciest app here.
• Trial only. Free access is a 7-day trial rather than an ongoing free tier.
• Day by day. Fitbod adapts each session rather than laying out the week ahead.

Fitbod Pricing

7-day free trial, then $15.99/month or $95.99/year.

The Bottom Line

Most workout apps started as digital logbooks: you create your routine, log your sets, and look at a chart. That model still works well for experienced lifters who already know how to program, and Strong and Hevy do it very well.

The category is changing. JEFIT, Hevy, and Fitbod now all offer some form of generated or adaptive programming, each in its own way. Gainr's take is a weekly AI Coach plan built around your schedule and equipment that you can adjust as the week unfolds, alongside free workout logging and progress tracking.

If that sounds like what you need, download Gainr for free on iOS or Android.
