I just wrote this Android app as a solo portfolio piece without carefully considering how to monetize it. At the time, I was more concerned with learning new APIs like Google Volley and also with creating an interesting side project to advertise my app development services.
Now, I have entire clinics in poorer countries like the Philippines and Nigeria which depend upon my free, ad-supported app.
I will soon pass a request limit and need to start paying API fees to Pearson which are quite a bit greater than my Google AdMob advertising revenue. If I do not find a way to gain more paid subscribers or earn more ad revenue, I will start losing a significant amount of money.
I want a way to keep my app alive for clinics in poor countries, but to hopefully also meet the break even point. Does anyone have any advice for a solo developer?
Thanks!
Here's the app:

You might also be able to negotiate a special rate (or even free) from Pearson as a charitable contribution. If their software costs are what threaten your financial stability, and it's for a good cause, they might be willing to write it off.
So talk to Pearson, and talk to nonprofit health care grant specialists. Those would be potentially more effective than trying to figure out how to monetize.
