1. So I have all of the back end code complete (all of the code for populating the library from the database), as well as the code for handling much of the annotations functionality. What is left is all of the UI work (the various dialogs, screens, etc). It's definitely handled in a different manner on iOS, so I'm working through figuring out all the differences right now. As I work through some of the initial research and growing pains, I should have a sense for how long it takes me to implement some of the UI pieces, and I should be able to provide a more accurate estimate on the potential end date. I can't be 100% confident about having it all done in February, but I will post updates as I progress further. Initially I was wanting to release the beta in stages, so that users could provide feedback about different parts of the application, but it seems like TestFlight is set up in such a way that I really need to have a mostly finished version of the product ready for testing before I can utilize it. So when the beta starts, it will cover the entire application from the start. Also be aware that my goal is to have the beta started in February - not for a public release of the application to be ready in February. The official release may not be until April or May, depending on how long the beta takes. 

2. A separate one-time purchase will be required for the iOS version, as I will be selling it through Apple's app store and there is no way around that. MobileSheetsPro is currently priced at $12.99, but it will most likely be increased to $14.99 in the near future.

3. I'm designing it so that all features will work across all operating systems. That means you can transfer a backup file from Android or Windows 10 and restore that on iOS and have immediate access to your entire library. Similarly, features like the library sync will work across platforms.

I know a lot of people are anxiously waiting for the iOS version and I'm going as fast as I can, but as I'm having to learn the ins and outs of iOS as I go, some of the initial research is taking extra time. I'm also updating some of my tools to automate things like transferring the localization files over from Android to iOS, so there is up front work that saves me time down the line. I'm also getting some part time help with some of the customer support starting next year which will free up additional time for me to speed up the development.

Thanks so much for your quick answer! I really appreciate the work you do, you are the most awesome dev. 
This info is really helpful, it’s easier to wait when I have a better picture of what’s happening and what’s to come. 
Don’t mind us impatient people, you are doing an amazing job and I believe most of us trust that the time you’re taking is necessary to get a great final result. 
Thanks again!
