> EDIT: Happy to see Milen's sibling comment about fixing breakage!! I realize you have to make a living -- is there a way to contribute for these new features (or is it a totally new app -- which is fine!).
I've considered the idea of letting other developers have access to the source code and help with the development. Unfortunately, I couldn't figure a way to make it fair - e.g., if someone starts contributing, do they start receiving a percentage of the proceeds? What's a fair percentage and what about multiple external contributors?
I could never come up with a workable model, so it's either fully open-source or proprietary. As I mentioned in another comment, I believe the way to go is an open data format which allows interoperability. This way there's no lock-in and competing apps (open or closed) can exist.
For what it's worth, the Monodraw data format is not secret, it's just compressed JSON. I haven't documented it because it's more of an implementation detail and I'd rather spend my very limited time on improving the product.
Thank you for the comment, apologies if I came off a bit antagonistic! It's just a little frustrating when you see really great apps potentially ending.
It's really too bad there's not a better indie-dev model for the App Store, if I am buying an app (I think maybe I maybe paid $19 for Monodraw -- totally worth it btw), am I buying the app as-is? or do I get updates ... if so how long should I expect to get them and are the updates minor fixes or bigger whizbang features.
I can see that once an app gets to a steady state, there's probably diminishing returns in putting a lot of effort into new features esp. if your market is small. On the other hand, if the app has some sort of subscription, now there is an expectation for updates (not unreasonable, but possibly the numbers might not work for the developer).
I think Pixelmoter sort of got this right, although they did release a Pro version separately (which I also bought). However, I suspect they're a much larger company and probably have quite a large market share and can afford to continue to release updates to keep it fresh (and for someone like me, the app is exactly what I need vs. say photoshop and the price point is reasonable).

Hope that provides a bit more context.
