How it works, in three easy steps

  1. You install a software program that uses your spare computing power to raise money for Air Ambulance.
  2. The software operates quietly in the background, coming to life when your computer is idle, enabling it to volunteer its spare computing power.
  3. Your computer teams up with other computers to solve complex online mathematical problems - a process called ‘mining’ - earning rewards for the charity.

You can make a real difference to Air Ambulance by choosing to donate your spare computing power now.

With your help, we can create the funds we need to achieve our mission.

How your donations help

We fly two regional air ambulances, across the counties of Warwickshire, Northamptonshire, Derbyshire, Leicestershire & Rutland. These two helicopters provide a rapid response to trauma and medical emergencies over an area of 3850 square miles covering many of the UK’s major road networks including the M1, M6, M69 and M42.

With an average response of just 13 minutes, between them they attend on average 6 missions a day. You may well have seen us in the skies above you. We’ve saved thousands of lives in our community. We need your help to save thousands more.

What will I earn for Air Ambulance

The amount you can earn each month varies, based on a number of different things this includes:
  • The amount of computer power you have
  • The amount of time your computer is plugin and not active
  • And the current market price for yur calculations, like the stock market this price goes up and down

Here is a basic guide

  • Basic Desktop: £4 - £20
  • Advanced Desktop: £25 - £100
  • Basic Laptop: £1 - £8
  • Advanced Laptop: £5 - £30

The more people that download the software the more we can achieve. For example:

  • 1,000 downloads = £250k
  • 5,000 downloads = £6.2m

Increase your impact

Beyond running the software you can increase your impact, like in more traditional ways of donating by getting others to contributor to your mission. We can then track and report on the impact you make.

Share with friends & family

The more people that download the software, the more we can achieve.

For everyone you get to download our miner, we track what they raise and report it back to you.

Share with companies

Companies you know or work for may have hundreds or thousands of computers and servers that are sat idle most of the time. This means their impact can be huge. Our software is designed to work for enterprises.

We can cover the cost of their electricity, turn that electricity usage green and then the rest can be donated to our mission.


Will using Cudo Donate slow down my computer?
It’s possible if the computers being used are particularly old, however the app is designed to scale with the available processing power. The app can’t use what isn’t there, so if the computer is showing its age then it may be a case of running the app only during down periods.
Does it know when to stop?
The software has been specifically designed to detect when the computer’s processing power is demand and scale backs its activity so as not to slow your computer down. It's important to us that mining crypto for your charity doesn't disrupt your day-to-day usage.
What are the environmental consequences?
It’s important to be mindful of the effect that mining could have on our planet, as the collective energy used for mining is significant. We take the impact of crypto mining on the planet very seriously. This is why part of Cudo Donates fees are invested in carbon credits, so every penny you raise through mining cryptocurrency is carbon neutral. You can read more about our commitment to the environment.
What personal information does the software require?
We hold no personal information, with your permission we ask for system information when we need to debug issues.
Will it affect broadband performance?
No. The amount of data we send is very small. To give you an idea, we download the size of a standard image every day. Updates to the software are larger, but this only happens every few weeks.
How much will I raise?
This entirely depends on the power of your computer - anywhere from a few pounds a month to a few hundred. This starts to add up, the more and people and companies that do it.
What are the security risks?
We go through multiple security steps to ensure the software is safe, including software signing, whitelisting with antivirus vendors, and independent security audits of our systems, to ensure we are always virus free.
