Common questions

The things people ask before they hit download.

Is Stronger free?
Yes. Stronger is free to download on iOS and Android, and you can start logging workouts straight away. Premium features come with a 7-day free trial, so you get to try everything before paying anything.
What is the Strength Score?
One number that sums up how strong you actually are. Stronger compares the weight you lift with strength standards for your bodyweight and gender, gives each of your 12 muscle groups a level from Beginner to World Class, and updates your score every time you train.
How is Stronger different from Hevy or Strong?
Most trackers show you a list of what you did. Stronger tells you what it all adds up to: a Strength Score, a muscle-by-muscle map of where you're strong and where you're lagging, and group challenges to keep you and your friends honest. We've written up honest comparisons with the big trackers if you want the detail. See how Stronger compares.
I'm new to lifting. Is Stronger still for me?
Definitely. The exercise library has 400+ movements with instructions and muscle breakdowns, and the app can build a routine around your goals and equipment. And because the strength standards start at Beginner, your early progress shows up fast, which is exactly when motivation matters most.
Can I build my own routines?
Yes. Create them from scratch, or let the app generate a plan and adjust it as you progress. Rest timers, progress charts, and your full training history are all built in.
What's included in the 7-day trial?
Every premium feature: your Strength Score, adaptive routines, the full exercise library, and more. If you decide it's not for you, you can keep using the free workout tracker.
