The E-Waste Crisis Is Getting Worse
Electronic waste is the world's fastest-growing waste stream. Millions of smartphones, tablets, and Android devices are discarded every year — many still fully functional. The toxic materials inside leach into soil and water when improperly disposed of, and the carbon cost of manufacturing replacement devices is enormous. Repurposing old Android devices as smart displays is one of the simplest ways to reduce your personal e-waste footprint.

AppCarousel Turns Old Android Devices Into Smart Displays
Instead of buying new hardware for digital signage, dashboards, or smart home displays, AppCarousel transforms the old Android device you already own into a fully functional always-on screen. No new manufacturing. No new packaging. No new shipping. Just software that gives old hardware a new purpose — and keeps it out of landfill.
No new hardware required
AppCarousel runs on any Android 8.0+ device you already own — old phones, tablets, even older smart TVs.
Extends device lifespan
Old Android devices that would otherwise be discarded get a second life as permanent smart displays — reducing e-waste at source.
Reduces manufacturing demand
Every repurposed old Android device is one fewer device that needs to be manufactured, packaged, and shipped.
Lower carbon footprint
Reusing existing Android hardware avoids the significant carbon cost of producing new consumer electronics.
The Impact Adds Up
When thousands of users repurpose their old Android devices instead of buying new hardware, the collective e-waste reduction is significant.
repurposed = ~30kg CO₂ saved vs. buying new hardware
repurposing old Android devices = ~3 tonnes CO₂ avoided

Our Commitment to Responsible Tech
At 360Wonder, we believe the most sustainable piece of technology is the one you already own. We design AppCarousel to be lightweight, efficient, and compatible with older Android hardware — because software that demands the latest device is software that drives e-waste.
Longevity over obsolescence
We actively support older Android versions so your existing devices stay useful for longer — reducing e-waste by keeping old hardware in service.
Efficiency by design
AppCarousel is built to run smoothly on lower-spec Android hardware, reducing battery drain and heat generation on old devices.
No unnecessary cloud dependency
Core smart display features work without constant cloud connectivity, reducing data centre energy consumption.
