Let’s talk.
Clear answers about the HOSFU range, product features and safe use.
No. Every current HOSFU model is an external, sit-on device used while fully clothed.
No. Every current HOSFU model is offered to men and women. Choose between features, not a gender label.
Gen 1 and Gen 2 work without an app. Gen 3 is controlled through the HOSFU app. Gen 4 supports the app and on-device controls.
Gen 3 and Gen 4 provide real-time training feedback in the HOSFU app. Product feedback does not diagnose a condition or replace professional assessment of technique.
Gen 1, Gen 2, Gen 3 and Gen 4 differ by contact surface, heat, reverse Kegel mode, app support, controls, feedback and battery life.
For Gen 4: Quick Comfort provides vibration and gentle warmth without active contractions. Professional Mode uses the HOSFU app and calibration for active training with pressure feedback. Changing modes? Switch off first, then turn on again and choose your next mode. They do not switch directly into each other.
