## CHMate Reviews in United States

### ***** "Favorite UI of any reader. Would be nice to have more features"
Perhaps I’ll get the paid version at some point, but the UI and the layout of the books that I am reading right now are perfect
-- burnsac100, 2023-09-19

### ***** "My favorite app for EPUB documents"
After posting a problem I was having, the Developer quickly responded. The problem was solved and now I’m happily loving this app again.
-- Zoé_NotCorded, 2023-07-25

### ***** "ios上少有的chm格式阅览器"
ios上少有的chm格式阅览器
-- 超爱吃零食的大脸猫, 2023-06-27

### ****- "CH Mate custom fonts"
iOS 14.5 update is blocking custom fonts in CH Mate app. How we can fix this problem. Please update the app. Thanks
-- A dipole, 2021-05-13

### ***** "Good app.. Could be improved.."
It’s a great app, especially when dealing with .chm files. Runs very smoothly on both iPhone and iPad. Some improvements could be done: especially more colour themes such as Sepia (cool for the eyes) and collection views of books (cover page display instead of title of the book and author’s name).
-- Dani philip 777, 2020-05-29

### ***** "Works for chm"
I read large chm manuals and it displays them well.  Plus it is free.  Thanks for making it.
-- X3x75, 2019-01-27

### *---- "Crashes on search after new iOS update"
Cannot search any CHM filed without the app crashing.
-- EricJHinojosa, 2018-10-02

### **--- "It Won’t Save Any Notes You Make"
This app. needs to be updated and bugs fixed. You can no longer make a note on something and have it save your note. Until this gets fixed, the app. isn’t worth the time and money.
-- mawee246, 2017-11-08

### *---- "I lost my money!"
It doesn't work. The application opens and closes immediately.
Dishonest seller! You should be banned from the iTunes store.
-- Finn93, 2017-09-13

### ***** "Mamun"
It's really the best at job. It's probably can do anything,at least from my point of view.
-- Castor roy, 2016-12-02

### ***** "Tried all the free ones, this is my favorite"
I read for work, so I needed something that was pretty solid & easy.

We are lucky their are a few options. This is by far my favorite. No ads, easy to use. 

I am considering buying now.
-- nsnook, 2016-08-02

### *---- "Useless"
On iPad Pro, CHMate will not open anything I tried, either from iCloud or Dropbox, PDF or ePub; and it also crashed.  Promptly deleting.
-- BAR112, 2016-04-17

### ***** "Suggestions"
Need support iPad pro Resolution and iOS multi-window
-- Muhannad.Al-Mukhtar, 2016-01-06

### ***-- "Update broke index"
Can no longer expand index lines, only all lines at once, whereas clicking on an index line opens a document page instead of expanding into index subheadings. I'm not on iOS9 since my iPhone 5 isn't supposed to work well yet with the update.

UPDATE: the pro ver$ion has the same bug.
-- MrPebius, 2015-10-09

### ****- "Problem after ios9"
Seems like highlight has a problem now allowing only 1 color. I like the program but seems like needs some updates for new iOS.
-- Nelsonsoft, 2015-09-24

### ***** "Swift"
This app can work greatly, using it more than a year now, so far, very sarisfied..
-- pak_tanggang, 2015-06-02

### ***** "Great customer support"
I've had this app for a few weeks and it's done everything I've wanted. I also found a bug, it was addressed and fixed within the same day! Thank you
-- aosaosaos, 2015-03-17

### ***** "Simple Clean Interface"
Best ePub reader I've used. Allows you to scroll rather than turn pages like iBooks, but unlike iBooks this app has an excellent and efficient filing system.
-- Eraulli, 2015-03-06

### ***** "Great app"
Great app. I use it to view a massive emergency medicine textbook and it works flawlessly.
-- afrycl, 2015-01-24

### ***-- "Crashes a lot after recent updates"
It was my best app but after recent updates, it ruined every thing.
After " search the whole document " it crashes
At the opening it expand all the document
The pictures are half dark
..... 😡
