Strong App

Strong App is a gym workout tracker built around progressive overload tracking and strength analytics. Developed by Strong Fitness Ltd, it targets lifters who want a straightforward way to log sets, track weight increases over time, and visualize strength progress without the clutter of diet tracking or social features.

How Strong App works

The core loop is simple: pick a workout, log your sets and reps with the weight used, and let the app track your progression over time. Strong App stores your full training history and uses that data to generate progress charts for each exercise. Its 1RM (one-rep max) calculator estimates your theoretical max based on the sets you actually perform, giving you a benchmark without needing to test heavy singles.

You can build custom routines from the exercise library or create your own exercises when the defaults do not cover your training style. The app supports rest timers between sets and lets you reorder exercises mid-workout. Logging is designed to be fast, which matters when you are standing in front of a squat rack between sets.

Strengths

• Progressive overload focus. The app is purpose-built for tracking whether you are actually getting stronger. It surfaces trends in volume and weight that are easy to miss when you train without a log.
• Clean logging interface. Entering sets, reps, and weight takes minimal taps. The app does not bury the core function behind menus or upsells.
• Progress charts. Visual graphs for estimated 1RM and total volume per exercise give you a clear picture of long-term strength trends.
• Custom exercises. If your routine includes specialty movements or equipment-specific lifts, you can add them to the library rather than substituting a rough equivalent.
• Offline functionality. Workouts log locally, so spotty gym Wi-Fi does not interrupt your session.

Limitations

• No nutrition tracking. Strong App does not track calories, macros, or meals. If you want diet and training in one app, you will need a separate tool or a different platform entirely.
• Limited free tier. The free version restricts the number of custom routines you can save. Serious users will likely hit the paywall quickly at $4.99/mo to unlock full routine and history access.
• No coaching or programming. The app does not generate training programs or suggest when to increase weight. You bring the plan; it tracks the numbers.
• Minimal cardio support. It is a lifting tracker first. Runners, cyclists, or anyone doing significant cardio work will find the tracking insufficient for those sessions.
• No social or community features. There is no feed, no workout sharing, and no training partners integration. That is a positive for some users and a gap for others.

Who it is for

Strong App fits best for intermediate to advanced lifters who already know what program they want to follow and just need a reliable, fast way to log it. Powerlifters, bodybuilders running structured hypertrophy blocks, and general strength trainees will get the most value from it. Beginners who need exercise guidance or program suggestions may find it too bare-bones on its own.

It is also a good fit for people who prefer a single-purpose tool. If you do not want your workout tracker to also be a calorie counter, social network, and meditation app, Strong App stays in its lane.

How it compares

Strong App occupies a different niche than many popular fitness apps. MyFitnessPal is primarily a nutrition and calorie tracking platform. It does have exercise logging, but it is not built for detailed set-by-set strength tracking or progressive overload analysis. If your priority is tracking what you eat alongside general activity, MyFitnessPal covers more ground. If your priority is tracking what you lift in detail, Strong App is the sharper tool.

Strava caters to endurance athletes, with deep support for running, cycling, and GPS-based activity tracking. It has a strong social layer and route mapping that Strong App does not attempt. The two apps serve almost entirely different training modalities, and some users run both: Strava for outdoor cardio sessions and Strong App for gym days.

At $4.99/mo, Strong App is competitively priced for a dedicated strength tracker. The value depends on how central weight training is to your routine and whether you need the depth of logging and charting it provides.
