[WA]

I have an app that also went for $1 for a bit. People who are willing to pay $1 also pay $2.

If this was my app, I'd simplify the pricing a lot. Get rid of the free tier. People who aren't willing to pay for your service should go somewhere else. Instead, give people a free trial for 30 days or whatever.

I'd make it so:

$2 = mixture of your current Amateur + Pro, maybe call it "Basic"

$5 = "Pro" with all features

Simple is good. You don't need 4 tiers if your target audience is kinda price sensitive. 2 is enough.
