Someone offered to buy an entire app from me, a paid iOS app that was making stable income and has a proven codebase. I quoted 80k (or was it 100k) and the enquirer was shocked, replying that he was assuming a 10k price tag. And he is a CTO of a startup.
There needs to be a clear distinction between pricing for an existing app vs pricing for building one from scratch. If the former this will be priced based on revenue, potential revenue and how much the owner wants to keep it. If building from scratch then the cost has to be based more towards developer/admin hours.
So given your app existed then potentially $10k could be a great price no matter how many hours you put into it if; you not particularly fussed about keeping it from an enjoyment sense, it makes sub $1000 per year in revenue and you don't see yourself creating significant future revenue from it.
