Wiistle is a free lifestyle app developed by Twelve22 LLC for iPhone users. It offers a unique and motivating way to train and improve your running or walking times. With Wiistle, you can create your own "Virtual Runner" that mirrors your past runs, providing personalized motivation and feedback.

The app records your run or walk times, capturing details like your pace on inclines and sprints at the end of a route. This data is used to create your Virtual Runner, which you can then race against in real-time. Wiistle provides feedback on how far ahead or behind you are compared to your Virtual Runner's times. A negative time difference indicates that you are ahead, while a positive time means you're behind.

What sets Wiistle apart is the customization it offers. You can adjust your Virtual Runner's completion time, and the app will automatically adjust its times throughout the entire route. This allows you to gradually increase the Virtual Runner's speed and work towards your goals. You can also pace with faster Virtual Runners to challenge yourself and improve your times.

It's important to note that Wiistle should only be used when it is safe to do so and you should always be aware of your surroundings. The app allows you to create up to three Virtual Runners for free, and there is an in-app purchase option for unlimited Virtual Runners.
