I would love to see an inplementation of this from an org with a more DuckDuckGo-like philosophy. Where personal and tracking information is simply not collected.
Linkpack does not collect all of your links and sends them to our servers. Only after tapping the share button in a particular folder, and only then, it makes a request to Dropbox API to collect just the links of this particular folder, in order to generate the page that you can share with your friends.
How are you planning to monetize and keep it going long-term?
Right now there a $1.99 IAP that enables extra functionality such as Reading Progress, Narration and more but -as we are in a really early stage- this might change in the future, depending on the features that will be implemented.
Example, my RethinkDB packet.
