⭐️⭐️⭐️⭐️⭐️ Best Workout App Ever — Hands Down!
Feb 27
itsdavidrosenberg
I’ve tried so many workout tracking apps over the years, and nothing even comes close to this one. This is by far the best app for tracking workouts and weights. It’s simple, powerful, and actually makes me excited to log my sessions.The interface is super clean and easy to use. Logging exercises, sets, reps, and weights takes seconds, and I love how quickly I can see my progress over time. The progress tracking is incredibly motivating — being able to look back and see exactly how much stronger I’ve gotten keeps me pushing for more every week.I also love how customizable everything is. You can build your own workouts, adjust exercises on the fly, and track exactly what matters to you. No clutter, no unnecessary features — just everything you actually need to improve.The stats and history features are amazing. Seeing personal records automatically tracked and having all my previous workouts organized perfectly makes planning my next session effortless.If you’re serious about strength training, muscle building, or just staying consistent, this app is a game changer. It’s reliable, intuitive, and honestly makes tracking workouts enjoyable.I can’t imagine going back to anything else. Absolute 10/10. 💪

Great Weight Lifting Tracker

If you are into tracking your everyday progress with your fitness goals, this is definitely the app for you. Very easy to use and self-explanatory and very customizable when you’re creating your workouts and if you like satisfying things adding plates to the barbell in the app is very satisfying feature and a good tool for adding up the weight so you don’t have to.

What I most like about the app is that it’s straight forward and easy to use. Simple yet clean design and I don’t waste too much time in between sets to track the progress.

• Finishing a workout now confirms first, drops empty sets and counts your personal records; cancelling a workout with logged sets asks before discarding. • The Previous column shows the sets from your last session of that exercise. • Deleted exercises stay deleted, and duplicate exercises are merged without losing history. • Edit a past workout freely: Cancel discards every change, Save keeps them. • Templates inside folders no longer show twice; sort by name or date; rename and delete with confirmation. • Plate calculator shows the correct bar and exact remaining weight. • New Support, Privacy and About in Settings, a refreshed icon, and support for iOS 18.
