Musku and Strong are two workout logs for iPhone and Android, ad-free, with a free plan and an optional subscription. Both apps organise your training into templates: Strong calls them “templates”, Musku “workout templates”.
This page is published by Musku. Every fact about Strong comes from its App Store and Google Play listings, its website or its help center, checked on November 11, 2026, and links to its source at the bottom of the page. When a feature is mentioned nowhere, we say so.
