Booster+
Evidence-based exercises for men's sexual health — pelvic floor training, breath work, and stress reduction. Ad-free, privacy-first, no account.
What it is
Booster+ is an Android app for men interested in improving erectile function, ejaculatory control, and post-prostatectomy recovery through daily exercise practice. Every exercise in the app is grounded in peer-reviewed clinical research, with the citations included in-app so you can read the source studies yourself.
The app guides you through short daily sessions — most are 1 to 5 minutes — and tracks your adherence over time. No subscriptions, no in-app purchases, no ads, no analytics, no account required.
