I launched the free version of Story View back in September and my main goal with it was to reach a wider audience of potential customers. My hypothesis was that it would be much easier to sell the pro license of the plugin to those who already used and liked the free version of it. It looks like I was wrong.
The free version got 60 downloads and with zero upgrades. I didn't send sales emails to those who downloaded the free version of the plugin. There was only one follow up email a week after they made the download. Only one person sent a response to that and it was about a download issue.
The UI of the free version contained several links that pointed to the PRO version of the plugin and I also highlighted what are the features that are only available for PRO users. It seems like that this wasn't enough to convince anyone to make an upgrade.
Maybe the limitations in the free version weren't enough, maybe they didn't want to use it after they give it a try. I don't know.
We'll see what happens now that only the PRO version is available.
