Most of us have an old Android phone lying around that we no longer use. It can’t handle modern apps, the battery doesn’t last a whole day, and the screen has seen better days. Still, such a device can have value – it just needs a new purpose. With the ZippyJog app, it becomes a motion sensor that sends data to a computer which generates a scenic landscape.

Reuse without unnecessary waste

ZippyJog uses the sensors in your phone to track your movement during activity – whether you're walking on a treadmill, pedaling a stationary bike, or just slowly walking with a walker. You don’t need anything fancy, so a phone you were about to discard is actually ideal.
This way, you give the device a second life and help the environment.

Basic treadmills and bikes without smart features? No problem

Many treadmills and stationary bikes people have at home can’t connect or send data. They're often older and simpler – maybe even obsolete – but you can often get them for free from someone who just uses them for storage.
That means even secondhand or forgotten equipment can be useful again. No need to invest in a smart treadmill that costs tens of thousands. A basic machine that does its job and a phone that can track what’s happening on it are enough.

What do you need to reuse an old phone?

• Android phone – it doesn’t have to be the latest model, even one that’s six years old will do.
• Battery life – it should last through the activity (typically 30 to 90 minutes).
• Mounting options – the phone can be in your pocket, a waist pouch, or strapped to your arm or leg.

And what about the computer?

ZippyJog requires a more powerful computer with a gaming graphics card to run properly. That’s the trade-off for a beautiful environment, smooth visuals, and the immersive atmosphere that a regular app can’t offer.
The good news is that many households already have such a computer, especially if someone plays games or edits videos. So again, you’re making use of what you already have – no extra investment needed.

Meaningful use of technology

This isn’t just about movement and health. ZippyJog connects physical activity with a mindful approach to technology. It shows that we don’t always need new devices – often, it’s enough to find new uses for what we already own.
