Wouldn't assume this; I've seen how dickish people can be to open source maintainers.
Sometimes people link to our "guides", like this one https://macrocodex.app/knowledge/measure/bodyfat/
my app is in fitness field https://macrocodex.app/ and the people who use it are:
1. Bodybuilders
2. Overweight / obese / skinny fat / underweight individuals
3. General gym crowd
Bodybuilders, well they immediately understand the app on first impression.
One user told me he has kidney disease and asked if I could add a “low protein” diet mode, so he could reduce protein intake below standard recommendations. I had never faced this requirement before, but after hearing him out, I decided to add it. This is just one of the many interactions.
Then there is another group, people who have spent a long time being underweight or overweight and have started attributing it to genetics. I often see posts like “I am genetically fat” or “I am an ectomorph / hardgainer"; "I can’t gain weight no matter how much I eat” in subreddits and fitness groups. Don't you dare to call them out of anything, they'll get mad! but are willing to give app try especially if they hear about it from someone else.
They typically use it for 2–5 weeks, and then they start gaining or losing weight depending on their goal. They are genuinely surprised that it’s possible.
Once they start seeing results, they usually just keep going.
I am not particularly good at communication, nor a guy with social skill.
If this is something you’re able to do and people like it, I think that’s great.
However, the post is about a paid app and that’s going to have a significant influence on the type of support requests you get, and whether or not it makes financial sense to develop according to those requests.
