What doesn’t seem professional to me (been working in the software industry for 15 years) is to identify the bugs, tell his clients that those were easily fixable and disappear right after that.
I’m sure it wouldn’t take too long to correct the only bug that really bothers me (sending 2 slices as one)…
I can understand some difficult issues in private life could give some excuses, but not “I’m working with LASERS now so I don’t have time to assume my responsibilities as a service provider”.
If he wanted that kind of latitude, he should have given the app for free or just enough to cover the expenses of publishing it in the Apple Store…
This is not a professional attitude. And by asking 25$ for an iPad app (that’s more than Animoog, Samplr and many other great quality music apps on the market), he should have actually expected what we “ask” of him.
