Going vegan really does make a difference!

“Each day, a person who eats a vegan diet saves 1,100 gallons of water, 45 pounds of grain, 30 square feet of forested land, 20 pounds of CO2 equivalent, and 1 animal's life.” — Cowspiracy

Climate change, ocean dead zones, fisheries depletion, deforestation, food safety, heart disease, obesity, and diabetes have all something in common: our demand for and consumption of animal products. By eliminating animal products (such as meat, dairy, and eggs) from our diet, we can reduce the amount of harm we inflict on the environment and on ourselves.

By simply entering your veganniversary (the day you became vegan) Cowculator calculates how much water, grain, forested land, CO2 equivalent, and animal lives you have saved by going vegan.

Impactful and well-made

Sorry about the negative reviews from carnists who don’t have anything better to do, hopefully this can balance it out somewhat, but you deserve the 5-stars regardless.

The app is really really incredible, even for how simple it is. The presentation on the main screen is elegant, the numbers are accurate, and the concept is great. It’s really nice to be able to see the impact you’ve had, and I’m sure this app has helped in motivating a lot of people to stay vegan. The anniversary is a nice touch too, and the kill counter is depressing, but I’m glad it’s there.

Thanks for what you’ve made, and also for the fact that it’s free.

I don’t understand why a lot of the featured reviews are one star from omnis talking about why they hate veganism. that’s so awkward, i wish we could report reviews on the app store. anyways, i got this app when i first went vegan and i like that i don’t need to keep track of how long it’s been, i can periodically check in and see what i’ve saved. i also like that it tells you your veganniversary! i like simplicity and this app is perfect, no annoying bells and whistles or useless features, just does what it’s designed to do. 10/10, visually appealing and a good motivator

Love it

It feels good to be able to see how many resources and animals you’re saving. Even though I’m aware of how many animals die each year it still shocked me to see how fast that counter is shooting up for many of the animals. So sad, but something I think needs to be seen.

It’s a shame that so many people are bad mouthing this app. I mean, why even bother? If you have nothing nice to say then don’t say anything at all. It’s not worth it and completely unproductive. There’s some strong ignorance and cognitive dissonance going on.
