Hmm, thanks for the suggestion, but:
The biggest issue is not money. I've been living with serious illnesses for close to 20 years now, and it's just not conductive to regular, predictable, productive work (for example, I've not been able to do much of anything for the last two weeks).
Hiring people, even if just for specific tasks, would bring complications too, I don't see it as a magic bullet.
Besides, since the app already has a paid version, I'm not at all sure that asking for additional donations would be appropriate.
