Good f'ing luck with that. 

You are barking up the *wrong* community if you think the tightwads in this joint will part with even a single satoshi if they can get it or something similar for free. That's not true of everyone here, but it definitely was my experience.

Seems like there is some sort of allergy or moral opposition to actually sending donations for mining/monitoring software around here.

Try building in an option for donation mining, that might have better luck.

Advertising a software product as free, and requesting donations as payment rarely results in you feeling truly compensated for your work; particularly in this industry. Getting mad because people aren't donating what you feel your software is worth kinda proves that you chose the wrong model.

Alternatively, convert what you have into a paid or ad supported product. Leave the existing product exactly as it is, offer an updated one via a private repo to people who 'donate'.
