Based on the feedback we receive, we'll add and modify the features as much as we can. *Please note: Flash Reader DOES NOT have advertisements of any kind. Services such as Instapaper, Pocket, website article saving and certain file-specific document conversions have limits and might require the Flash Reader Pro upgrade, which is a permanent one-time payment that unlocks all features of the app. Some services (including PDF and ePub importing, as well as Microsoft Office files like DOCX) require an active internet connection when importing. Also note that Flash Reader does not have voice support, so no text-to-speech or anything like that.
