what does the app do?
Please shoot me an email (the email address is in my bio) if you have an active Android developer account and are potentially interested in taking over the app; then I'll send you the info.
Why not just answer the question, even if somewhat vaguely (though not sure why)? Expecting every person to email you for a super secret private explanation? That’s… not in your best interest if you actually want to find someone interested. No one wants to email you to find out you made a basic note taking app of which there are a thousand and was why you couldn’t sell it, for example. But if it is something that sounds interesting — someone might be interested.
Otherwise, not to be mean, you’ll have a hard time finding someone who cares about another side-project dead app that couldn’t sell.
That’s just 2 cents though.
It's essentially a find-a-name-for-your-coming-child app for expecting parents.
You might find someone, but otherwise you’re really just better off letting it fade to obscurity. That’s a really crowded space with a very low cost of entry (development-wise). Unless there is something significantly novel that makes it stand out, there is no real value to anyone taking it over for you. If you’re that worried about your personal details, which Google already has (can’t I ring that bell), make your own second dev account and transfer the app or call any costs the price of the anonymity you seek.
