First time! – Wing by Sparo Labs Review

So the app is fun and easy to use,however you do a test blow first,if the test doesn't match the next blow,you have to do it over again, this happened to me several times u til I was finally able to match two blows,and then the test was so wildly wrong that I actually laughed! When your fev1 is as low as mine blowing multiple times is not only difficult but exhausting,I'd say a total redesign is in order.
