Studying Japanese using only a phone.

I live in Tokyo and Im pretty busy so basically all of my studying is done on the phone during commute time, gym time or whatever. Up to this point most of my study was memorizing kanji words and grammer patterns using various apps during the odd hours of the day and Im now at a level that I can read and understand N1 test materials though I still have to look up words or translate sentences here and there.

​

In preperation for this summer’s N1 test Ive started sentence mining the N1 past tests and Im interested in finding more reading materials that I can sentence mine. When I try to use kindle its hard to select text properly and I cant even look up words with okurigana half the time so its not a very useful source of japanese text. Basically I just wonder if anyone knows where I can access a lot Japanese text (that hopefully is at least a little interesting) using my phone to perfom basic functions like “send to anki”, “look up in takoboto”, “translate with deepL” without having to deal with obnoxious in app functions and dictionaries that I dont really need.
