Study the storefront
02

Separate demand from paid growth

Store rankings and revenue estimates describe market context. They do not establish ad spend, conversions or ROAS.

Waste of 2.99

This letterhead layout makes no sense. You can’t modify it really. Why is it so complicated to come up with an app that just does a letterhead in a normal way. The information is strewn all over the page. Why can’t I pick and choose what I want to be on the page. There are certain entries / information the app requires, that I don’t want on the page. But it can’t be eliminated. This was an irritating waste of $2.99. I’m going to create an app that actually can be used.

Needs work

Return address is jumbled up on letter. Can't remove horizontal blank space in return address. It takes to much work to correct issues. Should work perfect for price. Recommend NOT purchasing! I wish I could get my money back.
