Readler Customer Insights

1. Still, I found that main the reader part works much metter than other available free readers.I haven't used the app to full potential, but reading books that come in PDF format work well.

2. So I'll keep the other apps.So very close to being perfect! The only flaws I've found is that it doesn't seem to use baked contents on a pdf and instead just shows you all the pages.

3. comic page order tends to get corrupted (e.g. title page ends up in the middle of the comic; no other viewer has this problem with the same files), 2.

4. I debated bringing the rating down to 4 stars because of this but the rest of the app is so good it would be a disserviceI found this to be one of the better apps for reading and marking my pdf pages.

5. The zoom is bugged, as the upper part of the page will start at the upper margin of the screen and a strip will be covered by the not-so-ergonomic interface.

6. It's more comfortable to use the down volume to move to the next page rather than the up volume... Could you add a night mode in the next update?This is just the best PDF reader for Android ever! I literally can't express how much I appreciate both UX and UI of this application.

7. gallery browsing could use improvement when reading a series (read/unread marking, exiting to main folder after reading a volume).

8. I'm reading dark comics and the effect is ruined by the white background.works exactly as expected.

9. The page must revert to original small size (zoomed out) and then highlighted.

10. With comics, that means I either guess from the small page, or open it in another app.

11. I'd personally prefer the volume buttons switched to flip a page.
