Written for food bloggers deciding whether a recipe app is worth bothering with. Each one says where the other option wins, because a comparison that never concedes anything is an advertisement.
The established product in this space, and the more complete one. What their per-member pricing costs at 500 subscribers, what a flat fee plus a percentage costs, and the point where the percentage becomes the expensive choice.
You have probably already sold a PDF. Where that is still the right product, where it stops working, and why the sensible answer is both rather than either.
Whether an app cannibalizes your ad revenue. Which page views you would actually lose, roughly what they are worth, and when you should not do this at all.
Three pages, not thirty. We will write more when there is something true to put in them. Competitor pricing is checked against their own published pages and dated on each comparison; if something has gone stale, tell us.
