## CHMate+ Reviews in Vereinigte Staaten

### *---- "Some crushes"
Not searching in whole documents when the book is large ( 5000 page ) like Nelson textbook of pediatric
-- Salman dawood, 2018-10-24

### ***** "Great EPub CHM Reader"
Love this app!
-- Frank from NYC, 2018-04-29

### ***-- "Good app"
I like this app in that I am able to read the .chm books I have, however some of the functionality needs work. The buttons on the top that are supposed to allow you to bookmark pages etc, are hidden beneath the page and not accessible. With some clean up of function I would give it a higher rating.
-- Cdecker69, 2016-09-18

### ***** "CHMate Premium"
excellent app
-- Mmbeiruti, 2016-08-02

### ***** "Love & use this frequently"
I have been using this app for long. Very useful serves the purpose. Doesn't not annoy you to rate it in middle of your reading. 
Since this app is so useful to me & I admire that it never sends pops up for rating, I put in extra effort to search it in App Store just to express my gratitude to the app creator. Thanks.
-- mydocnan, 2016-05-18

### *---- "Never buy it, there are many ads in premium version"
After updating latest version of CHMate Premium, there are many ads in it. It is really terrible and disappointed.
-- Ezra.Wang, 2016-04-29

### *---- "Disappointed"
There is no help. Don't like the way to use annotation. Not worth the money spent
-- Lindielou2, 2015-12-11

### ****- "App crash after The last update"
Please fix this problem ASAP. I cannot access the app anymore
-- Alaseem, 2015-11-06

### ***** "A superb reader for chm & ePub ebooks"
CHMate Premium is the best chm e-book reader at App Store. It allows you not only to highlight but also to annotate a particular portion of texts that may interest you. Also, it allows you to import e-books from iCloud & Dropbox or Desktop web browser. Moreover, it allows you to organize your e-books based on collections. Although it is quite versatile, it is quite easy & smooth to use it. I highly recommend it.
##############################
[last review]
Better than ever! Now, it can read ePub e-books.
#######################
[Old review]
Several years ago, I suggested that the developers should have added highlighting & annotation ability in this app. Surprisingly, they did listen, and added these features in a short time. Ever since, I've been comfortable with using CHMate Premium! In a word, CHMate Premium is the best CHM e-book reader on the iOS platform.

####################################
[very old review] This is a very nice e-book reader for e-books in chm format. However, it would be perfect if the developer could add new features such as highlighting & annotation in the very near future.
-- Huang-Taiwan, 2015-10-28

### ***** "No question. THE BEST"
This app is so fluid and has a nice hierarchical view of the CHM-style navigation.

I tried the CHMplus Pro for $3 bucks less but it was really slow to turn pages. The navigation was bad. Multiple taps to open a search. Forget it.

I like that I can open files on Dropbox, but I would prefer to see Google Drive integration. 

Thanks.
-- Jason.0, 2015-10-08

### ***** "Good apps"
Please make it possible to share and open files with other apps and add wifi option for send receive files.
-- Moh.R, 2015-10-04

### ***** "Great app!"
If you need to use chm files, you will be ok with this app.
-- .zziggy, 2015-05-30

### ***-- "Needs work"
Not a lot of CHM choices worth anything out there. This seems to be the most robust but it's a pretty low bar given the field.

Current version (Dec 2014) crashes upon document search.

Suggestion:
Sync TOC when bookmark is selected
-- typo_kign, 2014-12-12

### ***** "Reporting a problem"
During searching in the app or inside one book,always force close happens in the recent update of the app.the older versions didn't have this problem
-- M.Alien!, 2014-12-08

### ***** "Can't imagine one day without this app"
This is the most perfect CHM reader for ios, specially for medical staff.
-- Parsa 20, 2014-12-03

### *---- "Disappointed"
I restored my backup and I missed my chm files.
Your app dont support "open in app" option for chm files.
-- Af12358467905326, 2014-12-01

### *---- "Crashes"
I imported a chm file into the app and it's been crashing on startup ever since.
-- meathpj, 2014-11-26

### ***** "Nice app"
Very nice app, works great!
-- Fei-Fan Zhu, 2014-11-13

### ***** "Great app!"
Used this app during med school and would consider this my favorite CHM app.
-- RJay, M.D., 2014-11-13

### ***** "Does it's job"
If you need to read chm files this does the job well.
-- Rxdiaz, 2014-11-13
