Strontr is now completely free while the app grows and improves. Lifetime PRO memberships remain safe and will be honored when subscriptions return.
This update includes improvements across the app, including faster loading of workout instructions and media, plus updates to workout routines, Evolve Plan, cardio tracking, stats, calendar history, and simpler settings screens. It also fixes AI generation issues and adds more polish throughout.
Strontr is still new, and your feedback means a lot. Thank you for using it and helping it get better.
