I’m finding that I often forgot what happens in the last issue/collection I read, or even what I’ve read. Thinking about a spreadsheet or Evernote or similar app to track what I read, perhaps write one sentence reviews or at least a rating.

Something on iOS so it’s always with me would be preferred.

Though about goodreads.com to include all books, but it doesn’t have many single issues.

What do you all use, if anything?

The most I do is not seal the bag of the most recent issue until the next one comes out. I'll glance through it before reading the new one (because I also can't ever remember what the heck happened a month ago!).

I will leave a bookmark where I left off in bigger trades and hardcovers. I've never liked reading more than 3-5 issues at a time of any one series.

I usually use the ComiXology app or the challenge threads. Bookmarks for large physical volumes.
