New features include:

• All alert sounds are now also played when the app is in the background or the screen is locked
• Get the most from Heart Graph with our tutorial videos, which are now linked from app settings
• Duration of your workout is now displayed in landscape mode on the iPhone and iPod touch
• We’ve added a new In-App-Purchase for supporting ad-free software
• Fix crash that could occur when recording very long workouts in the background
