### 5/5 — My Favorite Dictionary

*2023-12-16*

I love this app and use it daily. It’s placed at the bottom right on the screen so that it’s always available. I even have a paper copy on my night table. I have other dictionaries, but this is my favorite.

### 5/5 — Great dictionary.  Great app.

*2023-11-04*

American heritage is one of my favorite dictionaries.  So I am very happy it’s available on the Apple devices.  This app doesn’t have silly bugs.  It’s very stable.  Good product and I think the $20 for this dictionary was money well spent.

### 5/5 — YES!

*2022-12-23, version 10.0.11*

I finally got my favorite dictionary back when I was using the app thru ENFOUR I was always losing it every time. My iPad had to be updated. I bought it way too many times but now I bought it through MOBI systems and I have had no problems. It’s my good old favorite. Yes I had to pay $20 again but it was worth it. I love this dictionary it’s the best there ever was has the Hebrew and Greek meanings of words pictures it is invaluable to me in my personal study of the Bible and I use this dictionary all the time

### 3/5 — Meh

*2022-12-08, version 10.0.11*

It's needs a refresh. It feels like the designers don't actually use the app.

### 5/5 — Best English Dictionary

*2022-04-26, version 10.0.11*

I've used this dictionary for many decades through multiple editions and am delighted with the electronic version, which makes access even easier. Its special strengths, beyond very well thought out definitions, are excellent attention to etymology and explicit discussions of usage panel recommendations and sometimes disagreements. I was disappointed a year ago that my purchase did not carry over to a new iPad and I had to buy it again, and a third purchase came with a new iPhone. The management company could solve this only if I could come up with my original receipts and it wasn't worth searching for them. That's flaky, to be sure, but the quality of the dictionary is worth it anyway.

### 5/5 — Good dictionary

*2022-03-24, version 10.0.11*

Like the pronunciation feature, the images if applicable and been able to jump to words in the definition.

### 1/5 — Good App. Incessant and annoying prompts to rate.

*2021-09-28, version 10.0.11*

Excellent dictionary. Pretty nice app. Positive feelings about the app, however, are destroyed by the annoying prompts to rate the app. It seems every time I open it, I'm forced to click through a prompt to review the app. I'm working and want a definition. I don't want to be slowed down by intrusive prompts. I've finally given in and am reviewing in the hopes that the prompts will go away.

### 3/5 — Annoying pop-ups every time you open

*2021-08-06, version 10.0.11*

I literally was forced to review this app because of a pop-up that will not go away. What a disingenuous (to use a word) way to “earn” a reputation. Folks, the AHD content is excellent and licensed to a variety of apps. Some apps are designed better than others to deliver the same licensed content. This one annoys me. Even though it does have some good features.

### 5/5 — At the Ready

*2021-07-28, version 10.0.11*

The AH dictionary is available at any time to increase your knowledge of our glorious English language. I appreciate the derivation of many words as well as the available synonyms. Very easy to use. I've had hard copies of AHD from the first one issued. Worth the cost.

### 2/5 — Redesign

*2021-07-11, version 10.0.11*

Just don’t like the redesign near as much as the old. Upon launching the screen choices are more about selling the app to other (rate the app and share with friends). Generally speaking I want my dictionary to be a dictionary. Not some social app.
