Other than the obvious nook, kindle, dc comics, apps as such, there are few apps that are actually decent when it comes to trying to find good stories, mangas, comics, the whole shebang to read. So here are apps for each category that are ensured to feed your book hunger.
1. WattPad
I have talked about WattPad before, but it is an incredible sources to read story from thousands of authors, plus you can comment and be apart of group discussion on the books as they are being written. The book selection is very wide as well from well known classic to ridiculous fan-fictions they have it all in all genres so really can't ever go wrong.
2. Manga Bird
I've used plenty of Manga sites and Apps but this one is so far the best, hands down. They have an incredible selection and an ridiculous amount of chapters for each manga you find, they even have some pretty rare ones that I haven't been able to find any where else. If you are looking for manga, download this app before any of the others it will save a ridiculous amount of time.
3. Tapas
I found Tapas recently and they are absolutely adorable, they are very similar to Wattpad, but they have a much stricter policy on who they choose as authors, but they have a very wide variety and all of the stories I have read so far are amazing, and the comics are beautiful and adorable every time. If you love the goofy comics you see all over the internet you will love the comics on Tapas.
These are the three so far I have found to always save the day when I'm in need but never fear I'm always on the look out for apps that help me read on the go.
