Good now, hopefully better in the future

The app overall works really well as it stands, but it is obvious it still needs some work before I works consider it a daily-driver. Searching through some OPDS catalogs (using both Kavita and Calibre) will often crash when downloading and not display the entire catalog. Moreover, I would love to see more customization options as well as features. PDF's for example have basically no options (would be nice to have option to display two pages at once). It would also be nice to have more format compatibility in regards to comics as well as manga (which doesn't seem to be supported at all). Lastly, OPDS-PS would be the icing on the cake, allowing for book streaming/syncing to an OPDS server would allow users to read a book on any device and keep progress synced without having to download anything

Our next release targets specifically PDF, with new options to switch between scrolling/pagination, control the reading direction and use a dual page mode in landscape.

We'll look into both Kavita and Calibre but based on past experience, neither of them tend to stick closely to the OPDS specification, which might explain specific issues.

OPDS-PS falls into the same category as it's not really part of the OPDS specification.
Our plan is to build support for streaming comics through the Divina profile of the Readium Web Publication specification, which provides a lot more features than OPDS-PS but it should be possible to provide a bridge to OPDS-PS down the road as well.

Not sure where the disconnect is

I had to down this app to read an ebook from a publisher. I’ve tried following the directions from the publisher, looked at the help in the app and still can’t access the ebook. The publisher is not listed in the catalog of libraries, from the publisher end it says it cannot connect to iTunes and I need an Adobe login (I do). Very frustrating as I’d like to read the book on my iPad, but can only do it through the browser.

Aldiko Next does not supports the Adobe DRM. If you'd like to open an Adobe protected ebook, you can download the following applications:
- Pocketbook (free app)
- Adobe Digital Editions (free app)
- or Bluefire Reader (paid app)
