The Greatest Dictionary, a Pretty Good App

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.

My Dictionary

The physical one I use is GREAT so Thank You so much

Dyslexic bug

Dyslexic mode does not show the definition in dyslexic font when using the app on macOS 26

Formatting Broken

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

Worst Interface Small Fonts No Control

I never review, but I purchased this app with confidence from the previews in the App Store. I would advise you look in another direction if you need a clearer font. The left bar is good for navigating the content window is lousy. Do I want to spring enough 16 bucks after losing 13 on this. You can do better. 1 star.
