### 4/5 — The Greatest Dictionary, a Pretty Good App

*2026-08-21*

I recognize the virtues of other dictionaries and own many hard copies of different publishers, but I really believe the American Heritage is the best. So, I would have none other than the AH as my dictionary app.

The app works perfectly, but hardly achieves its potential for the year 2026. It neither needs an absurd list of new, hi-tech features nor can it be said to completely satisfy basic requirements.

Relatedly, I'm not sure this app has offline access, which means it's significantly less useful than it ought to be. Especially for the current price. For those who must have the AH, only this app will do. Others should consider another provider (Collins? Chambers?) whose app is more well considered.

### 1/5 — Formatting Broken

*2026-06-07*

With the upgrade to macOS Tahoe 26.5 The dictionary lost its formatting.

### 1/5 — Literally no support

*2025-11-13, version 16.0.1*

I purchased this app a few years ago and after updating my phone it didn’t work and asked to purchase it again. I don’t know how many times I have emailed the support team to solve this issue but an automated email is sent to me every time. Literally no answer or support. It’s disappointing that this team has no respect for the customer 👎🏻

### 2/5 — DEVIL

*2025-11-10*

DEMON

### 1/5 — Worse with each upgrade.

*2025-10-07, version 16.0.1*

Why must perfectly apps be broken?

### 1/5 — Request payment after installation

*2025-08-25*

This app requires payment after installation to work. It's a trap!

### 2/5 — 音声が聴き取りにくい

*2025-08-10*

内容は問題なくインターフェースも使いやすいのですが、音声の声が低すぎてとても聴き取りづらく、2,200円払いましたが別の時点を利用することにしました。

### 1/5 — Crashes on Opening

*2025-07-21, version 15.3*

I cannot get to the step of paying the in app purchase before the app crashes.

### 3/5 — New search interface is homely and hard to read

*2025-04-09, version 15.3*

The new edition of the app interface is not an improvement. The layout and ease of use seems to come from circa 1994. It feels like they did research on how best to make it difficult to read.

### 1/5 — Crashes Before I Can Activate

*2025-01-18*

App crashes before I can do anything with it.  Will stay open for about 6-8 seconds and then close.  Tried deleting, repowering the phone, doing both, reloading the app, etc.  using the latest iPhone model, and fully up-to-date on the operating system.  Will check back later and see if you get any updates that will keep the app open long enough to be able to activate it.
