Strong vs Hevy: Minimalist Workout Trackers Compared

TL;DR: Strong is the best pure workout logbook with an excellent Apple Watch app, Hevy adds social accountability and a generous free tier -- but neither app programs your workouts, tracks nutrition, or forecasts body composition the way Protokl does.

The Logbook Wars

Strong and Hevy are the two most popular workout logging apps for people who already know what they are doing in the gym. Neither one tries to tell you what to lift. They just give you a clean interface to record your sets, reps, and weight. Simple as that.

But simple is not the same as identical. These two apps make different design decisions that matter in practice, and your preference depends on what you value in a daily tool.

Strong: Speed and Simplicity

Strong has been the gold standard for minimalist workout logging since it launched. The design philosophy is clear: get in, log your workout, get out. No social feeds, no AI recommendations, no feature bloat. Just a timer, your exercises, and input fields for weight and reps.

The Apple Watch app is arguably the best in the category. You can run an entire workout from your wrist without pulling out your phone. For lifters who leave their phone in the locker or do not want distractions between sets, this is a significant advantage.

Strong supports supersets, tracks rest times, and provides basic progression charts. The routine system lets you save templates for your regular workouts and start them with one tap. The interface is fast enough that logging a set takes under three seconds.

The pricing model includes a free tier limited to three routines and a premium tier (one-time purchase or subscription) that unlocks unlimited routines and additional features. The lifetime purchase option is appealing for long-term users.

Hevy: Logging With Community

Hevy took the Strong formula and added a social layer. You can follow friends, share workouts, like and comment on each other's sessions, and compare PRs. The core logging experience is comparable to Strong -- clean, fast, and well-designed -- but the social feed adds a dimension that Strong deliberately omits.

The free tier is notably more generous than Strong's. You get unlimited routines, full workout history, and basic analytics without paying anything. Premium unlocks advanced analytics, custom graphs, and more, but the free experience is genuinely usable as your primary tracker.

Hevy also offers workout templates shared by the community. If you want to follow a popular program like 5/3/1 or PPL, someone has probably already created a template you can import. This saves setup time and gives beginners a starting point.

The social features are not for everyone, but for the people they resonate with, they provide real accountability. Seeing your training partner post their workout at 6 AM can be the push you need to get to the gym.

What Logbooks Cannot Do

Both Strong and Hevy are excellent at recording what you did. They are not designed to tell you what you should do. There is no progressive overload algorithm, no periodization intelligence, no recovery management. You bring the program; they provide the paper.

For experienced lifters with established programs, this is fine. You know you are running 5/3/1, you know today is squat day, you just need somewhere to write down 315 for 5 reps. A logbook is the right tool.

For everyone else -- people without a structured program, people who are not sure if their volume is appropriate, people who do not know when to deload -- a logbook is necessary but not sufficient. Recording random workouts does not make them effective workouts.

The bigger gap is the complete absence of nutrition in both apps. Your workout log exists in a vacuum, disconnected from the single biggest variable in your fitness results: what you eat. Strong and Hevy can show you that your bench press has stalled for three weeks, but they cannot show you that you have also been under-eating protein by 40 grams a day. The diagnosis requires data they do not have.

The Missing Feedback Loop

Training and nutrition form a feedback loop. Eat enough protein and hit a surplus, and your progressive overload becomes easier. Under-eat in a deficit, and your performance drops regardless of how perfect your programming is. Recovery, adaptation, and body composition changes all happen at the intersection of training and nutrition.

A workout logbook captures one half of this loop. Without the other half, you are flying partially blind.

What Neither App Does

Protokl closes the loop by combining workout tracking with AI meal photo analysis and body composition forecasting. Instead of logging your lifts in one app and having no idea how your nutrition is affecting your performance, everything feeds into the same system.

The AI meal photo analysis means nutrition logging takes seconds instead of being a separate chore in a separate app. Body composition forecasting using Aragon, Alpert, and Forbes models gives you forward-looking projections, not just backward-looking logbook data. And Apple Health integration with 50+ data types means your sleep, heart rate variability, and activity data all contribute to the picture.

Check out the macro calculator to see what your nutrition targets should be, then ask yourself whether a pure logbook is enough for your goals.

The Bottom Line

Choose Strong if you want the fastest, cleanest workout logbook available, especially if Apple Watch logging is important to you.

Choose Hevy if social accountability helps you stay consistent and you want a generous free tier with community workout templates.

Choose Protokl if you want your workout tracking connected to nutrition data and body composition forecasting instead of living in an isolated logbook.

Logging your workouts is step one. Knowing what to do with that data is where real progress happens.
