As @minzinger mentioned, PayPal will be added in for loading credit... stay tuned!
As for the apps... We know mobile activity notifications are super important, and definitely want to add them to the mobile app ASAP! They will unfortunately not be in the initial version of the new app, but will be added in a subsequent update just as soon as we can.
We're building the new apps totally from scratch for both Android and iOS, so we'll be adding in features like notifications brick by brick once the basics are in place. Deciding what to include and what must wait to be added later is pretty tough... Believe me I want to launch a bunch of cool stuff right now!
@UzukiCheverie what else would be on your list?
The mobile app will likely never match the website exactly in terms of functionality, and in fact they may become more different and focused in the future. Discovering, reading, liking, commenting/replying, subscribing, getting updates for series and activity, etc. all make sense on mobile (and maybe someday even things like checking on your comic's performance, support status, revenue stats, etc.), but others (like publishing episodes, managing support programs) may not and are probably best suited for the creator dashboard on the main website.
The mobile apps are first and foremost for reading comics on Tapastic, so the discovery, reading list, and reading parts are a no brainer. Comments and interacting with the community are super important too, though, so we're definitely anxious to make that a big part of the app too
