Readability indices assess how easy it is to understand a given text, and some estimate the grade or education level needed to fully comprehend it. If you want to make sure your writing is intelligible, they’re useful tools.

Readability is a small macOS app that aggregates several of these indices and uses all of them to analyze your text. It gives you an idea of how easy it is to read, along with other useful information and recommendations.

The app is as straightforward as any software you’ve ever used. All you have to do is paste your text in the main field, and it will be analyzed instantly. Below, you’ll see where it ranks on each index, with brief explanations provided.

Some indices will give you different results based on the text’s use case. You can select this from the top-right drop-down menu, and the analysis will be adjusted based on the target audience.

Depending on who you’re writing for, readability indices can provide useful guidance. They can help you simplify your text for a specific audience or change its structure to make it easier to read.

If you’re not familiar with these indices, you can ask the app to provide recommendations. These are based on an overall weighted score, and they let you know what can be improved to make it more accessible. The explanations are quite detailed and insightful.

Once you’ve analyzed your work, you can export the results to a nicely-formatted text file. This can be useful for providing feedback to students or employees under your supervision.

Readability is an excellent utility, allowing you to quickly assess the readability of any text within seconds. It gives you useful information and recommendations, and the UI is well suited for its purpose.
