Great Concept, Faulty App

I love the idea that walking + biking will offset automatically calculated travel emissions. For the most part, that is how OffCents functions. However, the app has several bugs—for example, the home screen feature displaying amount of emissions remaining to be offset always shows an incorrect number. On the Trips tab, trips remaining to be offset sometimes show up & sometimes don’t. Clicking the “offset” button sometimes works, sometimes lags, & sometimes crashes the app. These are not essential elements, but they do detract from ease of the app’s use.

The rewards are also, in my mother’s words, “a bit dinky.” Many are simply coupons you could likely find online. I understand that rewards are far from the main purpose of this app, but if you’re going to offer them, it would be far more enticing to be offered something substantial.

OffCents does a good job in being transparent about the types of offsets retired by the company, but making this a bit more immediately visible & interactive would be nice. Some sort of choice regarding which offset the user retires or more extensive background on the offsets would likely motivate offsetting more than offering coupons does.

Great concept, but flawed.

The app has a great concept but there are few things that make it fall short.
1. Steps/walking consistently underestimates.
2. The vehicle efficiencies are too high for some vehicles. Our SUV does not get 27mpg on our commutes, it gets 19 (hills, slowdowns, driving style, etc.
3. The price of a ton of carbon is too low to have any meaningful impact. Estimates for the cost of a ton of carbon dioxide emitted to full encapsulate the social costs and pay for the externality are around $80/ton in US. This app works out at a cost of $15/ton.
If the app developers think this is too high there should be an option for users to change the cost per ton, with $15-20/ton as a price floor/minimum.

Everyone should have this app

This app is freaking amazing to the point where it helped lessen my suicidal thoughts about being a burden on the environment. I love this app and think it’s one everyone should have which is why I gave it five stars. I have however come across a problem where my credits are not loading and I’m not sure why or how to fix it. I’m assuming that either it’s just my phone being annoying since it’s old or that the problem will get fixed in the next update.

Developer Response ,

Thank you for the review! We're glad you are enjoying the app. Please try out the Credits tab again, we have made a fix for it as you predicted! If you are still experiencing issues, please reach out to us at support@offcents.com.
