The charities

All our profits go to one of these charities. You choose which one in the app, and you can change it anytime in Settings.

  • GiveDirectly

    Sends cash directly to people living in poverty

    GiveDirectly sends money straight to people living in extreme poverty, usually by mobile payment, with no strings attached. Recipients decide for themselves what they need most: food, school fees, a new roof or a small business. Its work is among the most rigorously studied in global development, with many programs tested in randomised controlled trials. Since 2009 it has delivered over $1 billion to more than 2 million people.

  • Against Malaria Foundation

    Provides insecticide-treated bed nets to prevent malaria

    Malaria still kills around 600,000 people a year, most of them children under five. AMF funds long-lasting insecticide-treated bed nets, one of the cheapest and best-evidenced ways to prevent it, at about US$2 per net. All public donations buy nets, and every distribution is tracked and followed up. AMF has been one of GiveWell’s top charities for over a decade.

    • Founded 2004
    • Nets funded 450+ million

  • Médecins Sans Frontières (MSF)

    Emergency medical care in crisis zones worldwide

    Also known as Doctors Without Borders, MSF provides medical care where it is needed most: in war zones, epidemics, natural disasters and places where healthcare is out of reach. It was founded in Paris in 1971 by doctors and journalists, and won the Nobel Peace Prize in 1999. About 98% of its funding comes from private donors, which keeps it independent and free to speak out about what its teams witness.

    • Founded 1971
    • Active in 70+ countries
    • Staff 65,000+

    Fighting hunger and malnutrition globally

    Action Against Hunger treats children with acute malnutrition and helps communities get clean water, sanitation and a reliable source of food. It was founded in France in 1979 by a group of doctors, scientists and writers. Besides responding to emergencies, it stays for the long term, helping families earn a living and withstand the next crisis. In 2024 it reached 26.5 million people.

    • Founded 1979
    • Active in 59 countries (2024)

    Protecting children’s health, education and safety

    Save the Children was founded in London in 1919 by Eglantyne Jebb, who also wrote the first declaration of children’s rights, adopted by the League of Nations in 1924. Today it works on children’s health, nutrition, education and protection, and responds when wars and disasters hit children hardest. In 2024 it reached 113.6 million children.

    Protecting wildlife and natural habitats

    WWF is one of the world’s largest conservation organisations. It protects endangered species and the forests, oceans and rivers they depend on, and works to reduce the pressures on them, from climate change to overfishing. Alongside projects on the ground, it works with governments and businesses to change policy and supply chains. It was founded in Switzerland in 1961.

  • Amnesty International

    Defending human rights around the world

    Amnesty International investigates and exposes human rights abuses such as torture, unjust imprisonment, the death penalty and discrimination, and mobilises public pressure to end them. It was founded in London in 1961 by the lawyer Peter Benenson and won the Nobel Peace Prize in 1977. To stay independent of any government, it relies on its members and supporters, a movement of more than 10 million people.

Effective giving

Why we recommend the GiveWell Top Charities Fund

Not all charities are equally effective. Some programs do far more good per euro than others. Researchers estimate the best can be 10 or even 100 times more effective than a typical charity working on the same problem.

That idea is at the heart of effective altruism: using evidence and careful thinking to find the ways of helping others that do the most good, and then acting on them. You don’t need to sign up to anything to find it useful. We used it as a guide when picking the charities in the app.

GiveWell does exactly this, full-time. Its researchers dig through studies, costs and results, and its Top Charities Fund pools donations for only the programs they can show save or improve lives at very low cost. If you’re not sure which charity to pick, it’s a good default, which is why it’s selected when you first open the app. The others are well-known organisations doing important work, so you can also pick the cause closest to your heart.

Transparency

Where the money goes

  1. You buy extra minutes in the app. That is a purchase of screen time, not a donation, and the price is the same whichever charity you pick.
  2. Apple takes its commission and pays us the rest. Taxes and the cost of running the app come out of that.
  3. Everything left over is profit, and we keep none of it. We add up what was earned for each charity and donate it at the end of each year, not at the moment you buy.

The details are in our Terms & Conditions.
