LEROSA SUPPORT
Haptic-guided interval training for Apple Watch.
WELCOME TO LEROSA SUPPORT
LEROSA is an interval training companion designed for Apple Watch. It uses distinctive wrist vibrations to guide WORK periods, REST periods, countdowns, transitions, and workout completion—helping you stay focused on your movement instead of constantly checking the screen.
CONTACT SUPPORT
For technical assistance, questions, feedback, or feature requests, please contact:
When contacting support, please include:
• Your Apple Watch model
• Your watchOS version
• Your LEROSA app version
• A clear description of the issue
• The steps that caused the issue
Please do not send sensitive medical information or detailed Apple Health data unless it is specifically necessary and you choose to do so.
GETTING STARTED
Use the Digital Crown to select your WORK, REST, and TOTAL durations. Once the three durations are configured, tap START to begin your session.
LEROSA automatically alternates between WORK and REST phases until the selected total duration is completed.
HAPTIC GUIDANCE
During an active session:
• WORK is guided by one prominent wrist vibration every second.
• REST uses a distinctive two-vibration pattern.
• During the final countdown, progressively stronger vibration sequences prepare you for the next phase.
• The workout ends precisely when the total timer reaches zero.
The strength of haptic feedback may vary depending on your Apple Watch model, wrist placement, band tightness, and system settings.
If you cannot feel the vibrations, open Settings on your Apple Watch, select Sounds & Haptics, and confirm that Haptic Alerts are enabled. Wearing the watch securely against your wrist can also improve haptic perception.
PAUSE, RESUME, AND END
During the workout:
• Tap anywhere once to pause.
• Tap anywhere again to resume.
• Press and hold anywhere to end the session.
• Apple Watch system Pause and Resume controls can also control the active LEROSA session.
APPLE HEALTH
With your permission, LEROSA uses Apple Health and HealthKit to display workout information such as heart rate and Apple-estimated active calories.
Completed workouts are saved to Apple Health. LEROSA may also use previous LEROSA workout records to provide useful session comparisons.
If heart rate or calorie information does not appear, confirm that LEROSA has the necessary Apple Health permissions and that your Apple Watch sensors are available and positioned correctly.
You can manage LEROSA’s Health permissions at any time through Apple Health or your device settings.
WORKOUT SUMMARY
After completing or ending a session, LEROSA presents a summary that may include:
• Total training time
• WORK and REST time
• Completed cycles
• Active calories
• Heart-rate information
• Performance and cycle comparisons when sufficient sensor information is available
Sensor-based information depends on Apple Watch availability and may not appear during every session.
