Bottom line up front: Strong is the best pure logging app for strength athletes. The free tier covers everything most lifters need, and the interface sets the standard for what workout logging should feel like. If you want programming guidance or recovery integration, look elsewhere — but for fast, reliable, clean logging, nothing beats it.
What Is the Strong App?
Strong is an iOS and Android app purpose-built for strength training logging. It does one thing: helps you track workouts, monitor progressive overload, and review your lifting history. No coaching, no social feed, no recovery tracking — just clean, fast logging.
The free tier includes unlimited workout logging, a 450+ exercise library, rest timer, 1RM calculator, and full workout history. Strong Premium ($9.99/month or $29.99/year) adds custom exercise creation, workout themes, Apple Health and Apple Watch sync, CSV export, and detailed volume analytics by muscle group.
Where Strong Wins
The UX is best-in-class for strength logging. Opening the app, starting a workout, and logging a set is three taps once you’re in the session. The rest timer integrates without interrupting your flow — it starts automatically after logging each set. For high-volume training where you’re logging 20-30 sets per session, this friction reduction matters.
Workout history is where Strong earns its reputation. Pull up any exercise and see every session you’ve ever logged, with weight progression charted clearly. This makes progressive overload visible and sustainable in a way that’s hard to maintain with a notebook or generic fitness app.
The exercise library covers everything from powerlifting staples to obscure accessory work with proper form notes. You can be logging a new movement 30 seconds after looking it up.
Where Strong Falls Short
There’s no built-in programming or coaching. Strong logs what you do — it doesn’t tell you what to do next. For beginners who need structure, they’ll need to bring their own program or use a different app that includes one.
No recovery integration. HRV, sleep data, readiness scores — none of it connects to WHOOP, Oura, or any recovery platform. Strong tracks training load in volume terms but doesn’t factor recovery into recommendations.
The premium pricing feels steep at $9.99/month for a logging tool. The free tier is genuinely complete for most lifters, which makes the paid tier hard to justify unless you specifically need custom exercises or wearable sync.
Who Should Use Strong
Strong works best for: experienced lifters who follow their own program and just need clean data, powerlifters and bodybuilders tracking specific movements over time, anyone frustrated by bloated fitness apps that try to do too much.
Less suitable for: beginners who need programming guidance, athletes who want recovery tracking integrated with training load, or anyone who needs their strength app to also handle cardio analytics.
Final Verdict
Strong is the cleanest, fastest strength training logger available. The free tier is more complete than most premium apps from competitors. If your priority is reliably tracking your lifts and watching your progressive overload over time, it’s hard to beat. Score: 8.8/10.

Core Features That Make Strong Worth Using
Strong’s interface is built around a single priority: getting through your workout efficiently with all relevant information at your fingertips. When you start a set, you see the weight and reps from your previous session for the same exercise automatically — no hunting through history, no manual reference. This previous performance overlay is the most important feature in any strength app, and Strong executes it cleanly. The plate calculator shows exact plate combinations for your target weight, the rest timer starts automatically after logging each set, and the exercise library includes instructional notes for most movements.
The routine builder supports full periodization structures: you can set progression schemes, log supersets and dropsets with proper rest timer logic, and organize training into program-level cycles across multiple weeks. For powerlifters, this is meaningful — a 5/3/1 program with proper working sets, joker sets, and first set last backoff protocol can be built within Strong without hacky workarounds. The RPE logging option is a useful touch for lifters using feel-based intensity prescriptions alongside percentage work.
Strong Free vs. Strong Premium
Strong’s free tier limits you to three custom routines — a significant restriction for anyone following a program with more than three distinct training days. Monday/Wednesday/Friday templates work fine, but a four-day upper/lower split or a five-day PHUL program requires Strong Premium. The unlimited routine limit is arguably the single feature that makes or breaks Strong’s free tier viability for most intermediate and advanced lifters. Hevy, which offers unlimited free routines, is the natural comparison for anyone who needs more than three.
Strong Premium at $9.99/month or $49.99/year unlocks unlimited routines, advanced volume and frequency analytics, 1RM tracking over time, and the ability to export workout history to CSV. For lifters who pay for coaching or follow periodized programs, the analytics are genuinely useful — volume charts by muscle group and training frequency heat maps surface programming gaps that raw logs don’t reveal.
How Strong Compares to Hevy and Boostcamp
Strong versus Hevy is the central comparison for most strength training app shoppers. Strong has a slightly cleaner interface and better supersets and dropsets handling; Hevy has a fully free unlimited routine tier and social features for training with partners. For anyone who doesn’t need the social component and is willing to pay for Premium, Strong is arguably the more polished experience. For someone who wants everything free or trains with partners, Hevy wins on value.
Getting Started With Strong: Setup and First Workout
Strong’s onboarding is minimal in the best way. Open the app, skip the account creation if you want (you can use it locally), and start a workout. The exercise library is pre-loaded with hundreds of movements, and the default data fields — sets, reps, weight — are exactly what you need for 90% of strength training sessions.
The rest timer is one of Strong’s standout features: after you log a set, it automatically starts a countdown for your next set based on a configurable rest period. You can set different rest times per exercise. Small thing, but it removes the mental overhead of watching the clock between sets — a friction point that adds up over a 90-minute training session.
The plate calculator is built into every working set. Enter your target weight, select your available plates, and Strong tells you exactly what to put on each side of the bar. If you’ve ever done mental math mid-warm-up, you’ll appreciate this immediately.
Progress Tracking: What Strong Shows You Over Time
Strong’s history tab logs every workout with sets, reps, weight, and volume. The per-exercise history shows your progression on any lift going back to your first session. The 1RM estimator updates automatically based on your actual working sets — tap any exercise to see your estimated max over time.
Volume trends — total weekly sets and tonnage per muscle group — are available in the Analytics tab (Pro required for full access). This is useful for identifying whether you’re actually recovering between sessions or grinding the same muscles without adequate rest. Strong doesn’t interpret this data for you the way WHOOP does, but it gives you enough to make your own decisions.
One gap worth noting: Strong doesn’t offer periodization or programming. It logs what you do — it won’t build you a 12-week progressive overload program or adjust intensity based on performance. If you want app-driven programming, FitBod or a dedicated coaching app fills that gap. Strong is a recorder, not a prescriber.
Strong vs. Hevy vs. FitBod
Strong vs. Hevy is the main comparison. Both are excellent strength loggers. Strong edges Hevy on interface polish — the rest timer, plate calculator, and workout flow feel slightly more refined. Hevy edges Strong on free tier depth — you get full routine building and volume analytics without paying. If you’re a serious lifter who logs every session, either works. Strong Pro is worth it if the rest timer and polished UX matter to you.
FitBod is a different product entirely — it generates workouts for you based on muscle recovery and your available equipment. Strong assumes you know your own programming; FitBod is for people who want the app to decide. If you follow your own program, Strong is the better fit. If you want AI-driven workout suggestions, FitBod competes in a different category.
Frequently Asked Questions
Is Strong App free? The basic version is free with limited routine storage. Strong Pro ($4.99/month or $29.99/year) adds unlimited routines, full analytics, and custom themes. Most serious lifters will want Pro eventually.
Does Strong work offline? Yes — workouts are stored locally and sync to iCloud or Google when connected. Reliable in gyms with poor cell service.
Does Strong track cardio? You can add cardio sessions manually, but Strong is purpose-built for strength. For running, cycling, or heart rate-based cardio, use a dedicated app and pair it with Strong for your lifting sessions.
Is Strong App available on Android? Yes — available on both iOS and Android. The iOS version has been around longer and gets updates slightly earlier, but the Android version is fully functional and regularly maintained.
Strong App vs. Alternatives: How It Stacks Up in the Real World
Strong isn’t the only strength logging app, and depending on your training style, it might not be the right one. Here’s how it compares to the main alternatives after extended use of all of them.
Strong vs. Hevy: Hevy has better social features and a cleaner free tier. Strong wins on reliability, exercise library depth, and the smoothness of the logging flow during a live session. If you train alone and want zero distractions, Strong is the better tool.
Strong vs. JEFIT: JEFIT offers pre-built programs and more analytical depth on the free tier. But the UI is busier and logging speed suffers. For pure simplicity during a training session, Strong wins by a wide margin.
Strong vs. a spreadsheet: Spreadsheets give you unlimited flexibility and cost nothing. The trade-off is that logging on mobile mid-set is slower and plate calculator integrations don’t exist. Once your training history exceeds a year of data, Strong’s charts and PR tracking become hard to replicate manually.
The case for Strong comes down to one thing: it reduces friction during the session itself. You’re not navigating menus between sets. The rest timer fires automatically. Your last session’s weights are pre-loaded. Over hundreds of sessions, that frictionless logging compounds into a training history you can actually use — and that’s what turns a logging app into a performance tool.

Boostcamp occupies a different niche as a program library app: it provides free, complete implementations of proven powerlifting and strength programs — Wendler’s 5/3/1, GZCLP, Reddit’s PPL, Juggernaut Method — with automatic progression logic. If you want to follow a proven program rather than build your own, Boostcamp removes the programming overhead entirely. Strong serves self-programmed lifters or those following coach-written plans; Boostcamp serves lifters who want structured program implementation without the design work.
