FAQ

A few things
worth knowing.

Can I use Voltra offline?

Core workout logging works offline. Logged sets are saved on your device and synchronized when a connection is available. Open the app and load your training information while online before heading somewhere without reception.

Do I need to install an app?

Voltra runs in your browser. You can also add it to your home screen as a Progressive Web App for an app-like experience.

What can I track besides weight and reps?

Exercises can use weight, duration, or distance. You can also record unilateral sets, warmups and failure sets, and keep a note on each exercise in a program.

What’s included in Pro?

Pro adds unlimited custom exercises and programs, up to 20 exercises per program, and the full Progress view: workout trend charts, exercise progression with personal records and estimated 1RM, and the muscle-group body map. Your workout history, weekly summary, body weight, and each exercise’s best set and last session are free.
