Hi dear. Hope you are well. I am from Pakistan and I have been using your android application Reasily for a long time. That's an amazing epub reader in the Google Play Store. Now I'm writing to request you kindly create an application for .mobi ebooks. Because there's not any good application that could read .mobi ebooks. I want to remind you once there was mobipocket reader for symbian and pc, but this was discontinued many years ago. I hope you'll consider my request. Yours sincerely

Tried over a dozen reader apps before landing on this one. It actually works! No ads, no nagging, and it supports proper pinch-to-zoom on fixed-layout Pubs (the ones with pictures that every other app treats like a locked PDF). We can send rovers to Mars with AI navigation, but reading an illustrated book on a $1000 phone requires app-hopping detective work. Publishers (and some app devs) are the real clowns here. 🤡 Thank you, Reasily devs, for not being one of them.

For every book there's only slogan" unable to open".

Text you highlighted can nowhere be found. The UI feels sloppy and unresponsive most of the time. Anything you want to change in display options needs a new opening of the display options, as they close whenever you change something. Full screen is not true full screen. Changing pages is erratic. Highlighting text can move you several chapters forward or backward. My advice, delete this app and start from scratch.
