## Decimator Reviews in United States

### ***-- "Good but needs updates"
I love being able to look find the Dewey decimal number for certain topics for certain books but it needs to get more detailed. So many of my books are categorized under 813 or 823 but I know there is more after the decimal point. The app won’t tell me. I have to find other resources to tell me.

### *---- "Not impressed"
I wanted to find the number for "calculus". No luck. "Vietnam War". Nope. "woodworking". Nada. I'm not sure what this app is supposed to do, but it doesn't look up dewey decimal numbers for any but the most basic topics (or one of the detailed topics it has on file, such as "International migration and colonization").
-- RebeccaTVS, 2013-03-27

### ***** "Great for What it's Meant to Do"
It's always nice to have Dewey in your Pocket.
-- Perception Media, 2012-10-04

### ****- "Great! But Search function limited"
Very handy while browsing at the library.  Wish the search function would include more than just the official categories.  For example, including 'cheetahs' instead of just mammals.  Searching for 'cheetahs' should direct you to the mammals section instead of giving 'no results'
-- Hitting expert, 2012-09-01

### ****- "Searchable Dewey!"
I very much appreciate being able to search by topic or Dewey number. I've spent 30 years in libraries using the Library of Congress classification system, and am now re-learning the Dewey system. I could have used this app at work yesterday, but am happy to now have it in my toolkit. If this app was updated to be optimized for the iPad Retina display, I would give it 5 stars.
-- Paul down the hall, 2012-07-27

### ***** "Works Like 793.8"
Magic!
-- Atom!SF, 2012-03-23

### ***** "Nice and useful app"
I would never have known the dewey decimal number for the Arabian peninsula /for free/ without this app.
-- Thor-oh, 2011-11-11
