BurnFit's Smart History lets you recall past sessions and copy-paste them for quick logging.

I found this App from Facebook Ads. I just needed something to keep track of my workout log rather than the old paper and pencil way. I tried various workout tracking apps, but this one was the best app I tried so far. It's better than most apps you pay for.
App Store
Most intuitive and easy to use workout logging app I've found. I can input my data quickly between sets without any hassle. The 1RM estimates are really helpful for programming my next mesocycle. Highly recommended for anyone serious about tracking their lifts.
App Store
Everything on your phone, structured. One of the best apps for keeping your workouts organized. The programs are well designed and the exercise library is comprehensive. Great for both beginners and advanced lifters.
App Store
Indispensable app for gym-goers. The workout calendar keeps me accountable and the volume tracking helps me see my progress over weeks. Great motivation to work out consistently. The rest timer feature is also very convenient.
Google Play
Super easy to use with great routines! I like how it tracks everything and gives suggestions based on my goals. Perfect for staying on track.

I've tried many fitness apps, but this one finally stuck. The workout tracking is smooth, rest timers are helpful, and the plans feel realistic for busy weeks.
Google Play
Best gym app. Wide exercise selection, can create your own exercises, very user friendly and clean UI. The progressive overload tracking is exactly what I needed for my training.
Google Play
Really solid workout logger. The 1RM calculator and volume tracking features are great for powerlifting. Apple Watch integration in Pro is worth it. Only wish the free version allowed more than 2 routines.
Google Play
Best workout tracking app I've used. The exercise library is huge and I can add custom exercises easily. Rest timers and progressive overload tracking keep me consistent. Forbes award is well deserved.
