Lifters love Liftin’
This is the best workout tracking app I’ve found, and I’ve tried most (if not all) of them over the past few years.
“Easily would give 6 stars if I could. Compatibility between the phone app and watch is absolutely phenomenal.”
“It’s easy to use with a great and beautiful interface plus a rock solid and simple watch app.”
“The best strength training app for Apple Watch. I’ve tried quite a few and none are as clean, intuitive yet functional as Liftin.”
“Automatic progression makes it dead simple to follow a program, and the simple clear UI makes it fast and easy to track while at the gym.”
“Beautifully crafted workout tracking app with utmost attention to detail. Feels so native it could be made by Apple.”
“Straightforward and gets out of the way when in the workout. Has everything a person needs in a lifting app and none of the stuff you don’t.”
“I’ve probably tried every workout app under the sun and Liftin’ wins hands down on every single front!”
“I love this app! the apple watch app works perfectly, so im just leaving my iphone at home now”
“A very useful app, especially with its AI plugin integration, which makes creating and managing workout programs much easier and more flexible.”
“Been using Liftin’ for ten years now. Perfect gym companion for iPhone and watch. Updated frequently. Def recommend.”

A new kind of iPhone needs more than a stretched layout. Liftin’ was reworked for the Duo: layouts rebuilt for the wide inner screen, controls moved into vertical bars, and a half-open mode that splits the workout at the hinge.
