Very confusing for my age. Glad it was free, it would have been a waste!!!

I was excited with this application - the big but is you need to retype every activity every day - please add a way to just repeat the daily activities each day then this application would definately get used more and reach more of its potential.

Nice little app, useful and easy to use. Hope to see more features in the future! Good work!

Thanks, Clear Standards!

Really good deal for a free app! It's easy to use and well made...can't wait till I can offset the travel.

Does exactly what it advertises. Anything too complicated can confuse casual users. Great App!

This is a nice free app to give a rough estimate on your C02 consumption. It uses your starting GPS location and your final GPS location to calculate distance. This, of course, doesn't allow for the many twists and turns that can take place in a commute. You could actually drive around all day and the app would tell you 0 emissions.

Sounds great, about time a co2 tracker was created.

Yes - it is free; but no - I don't think it really does much to track one's carbon footprint. It is simply a calculator for "rough" calculation of travel distance - based on a very limited number of options: large car, small car, airplane, bus, etc. A much better idea would be to calculate by a vehicle's avg. mpg, allowing you to enter mileage and fuel consumed. I also expected some sort of calculation for daily home living, such as monthly electricity use or something similar. For me, I ride a bike 90% of the time. Wish there was a way to calculate how much CO2 I am NOT using ... But again, it's free, so I won't complain.

I have examined many carbon counter programs and websites, and just about all of them lack some fundamental options (Carbon Tracker is amongst those that lacks these basic options): Those of us who live in large metropolitan cities more often than not, live in apartments, so our power consumption is different. I almost always use the subway, so my carbon output is definitely different than those who drive the same distances as i travel on public transport (for that matter, what if i use the bus?). Also, I opted to use a company that uses wind power to supply my electricity. This would also impact my carbon output. And lets not forget about our shopping habits; do we shop farmers markets or stores that buy locally produced food, or do we nto consider this issue. How often do we purchase electronics, clothing, furniture, etc? All of these factors contribute to our carbon footprint. I really wish developers making carbon calculators would think about these issues. It would help us all make more of a difference in how we live. Fancy sites/applications are nice and all...but i know we can do better.

This is definitely something you get what you paid for. Since it is free, you can't expect much. It is nothing more than a trip calculator. There is no other type of activity available.
