We redesigned BlackPulse from the ground up to be cleaner, faster, and easier on the eyes. ### 1.1 — 2026-04-13 What's new in 1.1 Refreshed home screen with a cleaner workout pack grid and a new Import card for sharing workouts. Fixed a bug where background music would stay quieted after a workout ended on Android. Music now returns to full volume when you're done training. Polish across translations and visual details throughout the app. Thanks for training with BlackPulse. ### 1.0 — 2026-04-12 No release notes. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
