What if you made the app cost $0.99 and that included the first postcard?

You get far, far fewer purchases, but each purchase is a far, far more qualified customer, plus, you can almost break-even on the one-and-dones, and you may make enough money on the breakage to make it tiny profitable.

I get that tiny profitable isn't a VC's goal, but for a side project that's dying anyway, this might make the runway infinite, which you could use to rattle around and maybe find a winning model, or just let it run and not cost you much.

Problem is the app gets no downloads organically. It costs me 0.50 per install for the free version via Facebook ads, and this is pretty good.
