Yes, 4500. That's some type of milestone because it's taken ages for the numbers to rise from about 4300 users. There were a few dips where I lost users but no matter - the point of Resus Algorithms is to get those algorithms into the hands of those that want and need them.
The story on iOS is a little different.
In the Google dev console I can see downloads AND current installs. On iOS I can only see downloads so I've no idea how many people are still using using Resus Algorithms.
On iOS there are 4910 downloads. On Android there are actually 7570 downloads. 3000 people uninstalled Resus Algorithms on Android. Can I accept the same proportions on iOS?

The latest NHS numbers, from this link - http://www.nhsconfed.org/resources/key-statistics-on-the-nhs - state there are 518864 doctors and nurses in the NHS at the moment.
So I have 1.81% penetration of my potential users!

You can fail but you can't fail too many times. It's a bit like R-Type in that sense, and you can buy power-ups and extras (though I can't find the heart refill anymore, sadly). There's even a timed practice that really puts the pressure on.
So as you can tell, if you've ever thought about th…
