## What is GreenLog STS?

GreenLog — Green Choices. Real Savings.

Rode your bike today? Exported solar? Log it and watch your savings stack up. GreenLog tracks your money and carbon impact with Australian data.

Most of us make greener choices every day without ever knowing what they're actually worth. GreenLog changes that. It turns every bike ride, bus trip, and sunny day into a real dollar figure — so you can see exactly how much your lifestyle is saving you and the planet.

TRACK YOUR TRAVEL SAVINGS
Log trips by foot, bike, e-bike, scooter, bus, or train and GreenLog calculates how much you saved compared to driving. Fuel costs, CO₂ avoided, and equivalent trees planted — all tracked automatically using current Australian fuel prices and emissions data.

MONITOR YOUR HOME ENERGY
Whether you have rooftop solar or you're just keeping an eye on your grid usage, GreenLog gives you a clear daily picture of your energy costs and savings. Enter your solar generation, grid import, and feed-in figures and see your net bill and carbon footprint at a glance.

SEE YOUR TOTAL IMPACT
The dashboard brings everything together — total money saved today, this week, this month, and this year. Alongside your running CO₂ total and the number of trees your choices represent. Small actions add up fast when you can actually see them.

BUILT FOR AUSTRALIA
GreenLog uses real Australian electricity rates, feed-in tariffs, petrol prices, and grid carbon intensity figures. No generic global estimates — just accurate numbers relevant to where you live.

YOUR DATA, YOUR DEVICE
Everything stays on your phone. GreenLog doesn't require an account, doesn't collect personal data, and works completely offline. Export your logs any time as a CSV.
