Point your camera at any appliance. Pinch your fingers. Know instantly what it costs you and the planet.
Last month, my dad got our electricity bill and just stared at it.
He couldn't understand why it was so high. He had no idea which device was the problem. Was it the iron my mum uses every morning? The old fridge that runs all night? The TV nobody turns off?
He just paid it. Like he always does. Because there was no easy way to find out.
That moment stayed with me.
Millions of families across Nigeria, India, Ghana, Kenya, across the entire world pay electricity bills they don't understand. Not because they're careless. But because nobody ever made it simple enough to see where the money is actually going.
So I built EcoScan for Earth Day.
- 📷 Point your camera at any electrical appliance
- 🤌 Pinch your thumb and index finger together
- 📊 See exactly what it costs you per month — in your local currency
No typing. No forms. No complicated settings.
Just point and pinch. Like magic.
The moment you pinch, Gemini 2.0 Flash Latest looks at your appliance and tells you:
- What it is — even if you don't know the name
- How many watts it drinks every hour it's on
- What it costs you per month in your local currency
- Your CO₂ footprint from that one device
- One simple habit to cut the cost immediately
- A better alternative available in your country
Then your live dashboard builds up as you scan more devices — showing you the full picture of your home's energy use with real charts and real numbers.
- The average household wastes 30% of electricity without knowing it
- A single electric iron running 2 hours a day costs ₦8,400 per year in Nigeria
- An old fridge running 24/7 can cost 3× more than a new efficient one
- If every household reduced energy use by just 10%, we'd offset hundreds of millions of tonnes of CO₂ every year
My dad didn't need a lecture about climate change. He needed to know which appliance was eating his money. That's EcoScan.

My dad still doesn't know which appliance was draining our electricity bill. Now he can find out in 3 seconds. That's why I built EcoScan. 🌍
