Well actually if you can't donate I'm sure Schturman would appreciate it the same if you helped out in the thread helping others out (especially since you know the solutions to many of the issues you faced) or now that the subject has been broached; create a wiki page for his app...

After all nobody does these apps for the money (Far more can be received doing for iOS or Android with much less effort)...We are in this community first and foremost by our passion so monetary concerns are not considered...
