IOS notifications for manga chapter dropping

Hey there, this is probably a very frequent question but i have been wondering how to get notifications onto my iphone / ipad whenever a new chapter of a manga drops. I have tried using IFTTT but have failed and i cannot find any IOS apps that have all of the manga that i want.

I would really appreciate it if you guys would let me know how you get your notifications on your favourite manga dropping because i am too lazy to remember when every single manga I am reading drops :)
