I think it would be best if any software like that were open source, and to be honest the masternode checker too, or is it already? I don't want to take anything away from your work, but I think the need to trust should be reduced when possible. What do you think about setting a target of Dash donations to publish the source code? I would be more than willing to contribute.
If I was to make and release an app that managed MNs and connected and communicated at that level, yeh, I agree that open source would be essential really.
As for the alert app, as it is, it only reads publicly available data using an address you give it. Not a lot of point. Plus, everyone would then see how terrible my development skills are
