The best free workout apps.

What to look for in a free workout app

Most people searching for a free workout app already know what frustrates them about their current solution — a spreadsheet that is clumsy to use mid-set, a notes app that loses the previous session's data, or an app that turned a core feature into a paywall. The criteria below are the features that genuinely affect the quality of a training session.

• Fast logging. You are between sets. Your heart rate is elevated. You have thirty to ninety seconds before the next set starts. In that window, the app needs to let you record weight and reps in two or three taps and put the phone down. Any more friction than that and you will start skipping the log mid-session — which defeats the purpose. The single most useful feature for fast logging is the previous session shown inline: the weight and reps from your last workout displayed directly beneath each active set. You do not need to tap back, remember, or estimate. This pattern — popularised by Hevy — has become the de facto standard for serious tracker apps.
• Progression guidance. A log records what you did. A good app tells you what to do next. The difference between recording 3x10 at 60 kg and knowing whether to add reps, add weight, or hold steady this session is the difference between a diary and a training tool. Basic apps leave progression entirely to you. Better apps surface your trend over time. The most useful apps implement a progression method — double progression, percentage-based loading, or reps-in-reserve autoregulation — and generate a recommendation each session. Look carefully at whether this is included free or gated behind a subscription.
• Rest timer on the lock screen. Rest periods matter for hypertrophy and strength. Research supports two-to-three minute rests between hard sets for maximum stimulus. An app without a rest timer forces you to use a separate clock — a context switch that risks losing the log screen. A rest timer that stays visible without unlocking your phone is significantly more useful than one that disappears when the screen locks.
• True offline access. Gym WiFi is unreliable. Mobile signal in a basement weight room can drop to zero. An app that requires an internet connection to log a session will fail you on the days it matters most. True offline support means data is stored locally on the device and syncs when connectivity returns — not just a cached interface that breaks without a server.
• Personal records and progress charts. Automatic PR detection — flagging when you lift more than ever before on a given exercise — is a small but meaningful motivator. Volume charts by muscle group over time tell you whether you are actually accumulating more work across a program, which is a more reliable signal of progress than any single session.

The freemium trap: free vs. truly free

The fitness app market is dominated by freemium products. The core experience is free at download, but the features that make the app genuinely useful — detailed analytics, custom programs, progression tracking, historical charts, coaching tools — are locked behind a monthly or annual subscription.

This is not inherently wrong. Developers need to sustain their products. But it creates a specific problem for users who search for a 'free workout app': the app you download and start using for free may become a worse version of itself the moment you want it to do something meaningful.

When evaluating any app, check the current pricing page directly — not a third-party article (including this one). Free tier boundaries change with product updates, and what was free a year ago may not be today. The inverse is also true: some apps have expanded their free tiers over time.

A genuinely free app — one with no subscription and no paywall on core features — is rare in this space. Where one exists, it is worth noting explicitly. Apps supported by ads represent a different trade-off: you pay with attention rather than money. Whether that is acceptable depends on how often you encounter ads during an active session, which is hard to evaluate before installing.

The main categories of workout apps

Workout apps occupy several distinct niches. Understanding which category fits your training style narrows the choice quickly.

• Strength trackers (log-first apps). Built around logging sets, reps, and weight. The primary screen is the workout log. They typically include a routine builder, exercise library, rest timer, and progress charts. This category is the direct digital replacement for a gym notebook. Most well-known free trackers — Hevy, Strong, and similar apps — fall here. The differentiator is usually UI quality, exercise library depth, and what is gated behind a subscription.
• Guided training apps. These apps provide pre-written programs and tell you exactly what to do each session. The logging is secondary; the programming is the product. They are well-suited to beginners who do not yet want to write their own programs, or experienced lifters following a specific coach's methodology. The trade-off is flexibility — adapting a guided program to your available equipment or recovery level can be clumsy. The best content is usually what is being sold.
• All-in-one fitness platforms. Large platforms attempt to cover strength, cardio, nutrition, recovery, and wearable data in one product. The breadth can be appealing, but depth often suffers — the strength logging is rarely as fast as a dedicated tracker, and the cardio features rarely match a dedicated running app. These platforms are heavily freemium: the free tier offers a taste of every category while locking the useful depth of each behind a premium subscription.
• Cardio and running apps. GPS running, cycling, and outdoor activity trackers are a distinct category with different technical requirements — accurate location tracking, route maps, pace analysis, wearable integration. These apps are not typically useful for strength training, and vice versa. Athletes who do both often end up using two separate apps.
• Hybrid trackers. A smaller category: apps that combine resistance training logging with native GPS cardio tracking. The most useful setup for athletes who combine lifting with running or cycling, because all training lives in one place. The combination is uncommon in free apps.

Well-known trackers: Hevy, Strong, and similar apps

A few strength tracker apps are mentioned repeatedly in forum recommendations, subreddit guides, and 'best workout app' lists. It is worth naming them honestly — including what they are known for and where they tend to draw the line between free and paid.

Hevy is widely regarded as having one of the cleanest logging interfaces in the category. The previous-set-inline pattern it popularised is now the benchmark other apps are compared against. It has a strong social component — you can follow other users, share workouts, and browse community routines — which is a genuine motivator for some people. Hevy's free tier is relatively generous for core logging, though some analytics features are part of the paid tier. Check Hevy's current pricing page for the latest boundaries.

Strong has been in the market for longer than most trackers in this category and built a loyal user base around a straightforward, no-frills logging experience. It is well-regarded for reliability and ease of use. Like most apps in this space, it operates on a freemium model — the free tier covers basic logging while more advanced features require a subscription. For a detailed comparison, see our best free Strong app alternative guide.

Other log-first trackers occupy niche audiences — some focused on powerlifting, some on Olympic lifting, some built around specific programming methodologies. The common pattern across the broader field is: solid logging, some form of freemium, and no built-in auto-regulation.

Where SammaGym fits

SammaGym is a free-forever workout tracker. No subscription, no ads at launch, no features locked behind a paywall. It is built as a Progressive Web App — you open it at app.sammagym.com, add it to your home screen, and it behaves like a native app with offline support.

The design philosophy is offline-first: all data is stored locally on your device using IndexedDB. A session logged with no internet connection is saved immediately and syncs to the cloud when connectivity returns. There is nothing to lose if the server is unreachable.

• Previous set shown inline. The last session's weight and reps appear in grey directly below each active set as you log — the same pattern that makes fast logging possible.
• Auto-regulated progression. After each session, SammaGym generates a suggestion for the next — add reps, add weight, or hold steady — using double progression combined with reps-in-reserve (RIR) feedback. You rate how close to failure each set felt; the app adjusts accordingly.
• Rest timer on the lock screen. The countdown is visible without unlocking your phone, so you do not need to keep the screen on between sets.
• Cardio GPS. Runs, walks, and bike rides are tracked natively with distance, pace, elapsed time, and a route map. No second app needed.
• PRs flagged automatically. Personal records are detected and marked as they happen.
• Volume and progress charts. Training volume by muscle group is charted over time. Progress photos are stored locally.
• Offline-first. Full functionality without an internet connection.
• Coaching toolkit. Create and manage programs for clients, review their logged sessions and progression data — all included free.

The progression system is the most meaningful differentiator from a basic log. The foundation is double progression: work within a rep range (for example, 8–12 reps per set). Add reps each session at the same weight until you complete all sets at the top of the range, then increase the weight by the smallest increment and restart from the bottom. Layered on top is reps-in-reserve (RIR) autoregulation — after each set, you rate how many reps you had left before failure. The app uses this signal to calibrate the suggestion: consistently high RIR means more aggressive progression; hitting RIR 0 without completing target reps means hold weight and focus on technique. This approach draws on the evidence-based frameworks of researchers including Dr. Mike Israetel (MEV/MAV volume landmarks) and Jeff Nippard (RIR autoregulation). You log honestly; the app does the calculation.

SammaGym does not have a social feed. Following friends, sharing PRs, and community accountability are genuine features in apps like Hevy with no current equivalent in SammaGym. If social motivation is central to your consistency, that is an honest reason to choose a different app. For more direct comparisons, see best free workout tracker, best free Hevy alternative, and best free Strong app alternative.

How to choose the right app for you

With the categories and main options laid out, the decision comes down to four questions.

• 1What does 'free' actually mean for this app? Check the current pricing page for the specific features you need — progression tracking, charts, history depth, coaching tools. Do not rely on what was free at launch or what a review article says.
• 2Do you need cardio and strength in one place? If yes, the field narrows significantly. Most dedicated strength trackers have no GPS cardio, and most cardio apps have no serious strength log. SammaGym is one of the few free options that covers both natively.
• 3Do you want progression guidance, or do you prefer to program yourself? If you have a coach, follow a written program, or are experienced enough to program your own progressions, a basic log may be all you need. If you want the app to tell you when to add weight, look specifically for whether auto-progression is free or paid.
• 4How important is social accountability? A social feed with friends and community can be a real motivator. Apps without it are not better or worse in absolute terms — they are a different trade-off. Weight this honestly before deciding.

The practical approach is to narrow to two candidates and run them in parallel for two to four weeks. Log the same sessions in both. The one with less friction — the one you actually reach for mid-session without thinking — is the right choice.

Open app.sammagym.com on your phone, add it to your home screen, and log one session. The previous set will appear inline on your second visit — that is when the value of keeping a log becomes concrete.
