May not be issue you need to solve right now. Your's is not "a project that gives context to news through history" @$1.00 per month. If the market wants it, it should work at $1(+$0.30 +2.9%)per month also. So just charge $1.49 per month and move on. Once you have a 1000 users, you can think about optimizing things.
You're right. I decided to move on... I agree. Thanks. But I don't get your comment about "yours is not". You mean is not necessarily a $1, right?
You can experiment to find out what that "right" or "best converting" price point would be.
"Free to start" may very well end up being the answer. Here are 2 examples one from pubilshing and one about starting with a price and using data to uncover insights about the "right" price. You will see the 30 cents is not the biggest problem you are going to have in pricing. :-)
