Doesnt work on iPad Pro

I downloaded and installed SPMulti Track last Sat. It would only open twice then crashed out of the four or five times I tried the FREE version.
Then I tried to upgrade and get rid of the ads to see if that would work.. It didnt..
It doesnt open at all even after deleting and reinstalling several times.
I submitted a report to support asking for my money back 5 days ago and havent heard a thing back.
Dont waste your money!
