3. Add Grammarly to an iPhone

If you’re adding Grammarly to an iPhone or other iOS device, visit the App Store to get Grammarly. First, search for the app and select “Get” to get the free app. 

Once you download the app, you’ll need to configure it. First, log in to your Grammarly account, and follow the on-screen instructions. You’ll then be able to check your spelling and grammar on Safari or within Grammarly itself. You might also be wondering how to change Grammarly language preferences.

4. Add Grammarly to an Android Device

If you’re adding Grammarly to a mobile device running Android, go to the Google Play Store to download “Grammarly Keyboard.” Then, tap “install” to install the app. 

Again, you will need to configure the keyboard. First, open the app and log in with your Grammarly account information. Then, tap “Add Grammarly Keyboard.”

This will bring up a toggle switch. Turn it on and press “OK.” 

Now, tap “Switch Input Methods” and check the box next to Grammarly, then hit “Got It.” This configures the Grammarly keyboard to serve as your preferred keyboard when you start typing in a text field. It will start checking for typos and grammar errors right away once configured.

Log in to your Grammarly account and add the Firefox, Safari, or Chrome Grammarly extension to use

Though it’s technically not suing Grammarly on a new device, you can add it as a browser extension instead of putting it on your device. Log in to your Grammarly account and add the Firefox, Safari, or Chrome Grammarly extension to use the grammar checking tool while typing in your web browser.

Consider Grammarly Business for More Devices

If you need more than five devices, often because you manage a team of people, you will want to purchase a Grammarly Business account. 

Grammarly Business allows you to have an account for up to 149 team members. The pricing for Grammarly Business is based on team size, so smaller businesses pay less. Grammarly also offers Grammarly Enterprise, which has an unlimited number of team members you can add to the account.

Much like the premium version of Grammarly, Grammarly business offers a grammar checker, spelling checker, and plagiarism checker. It will also help with word choice, passive voice, and the overall tone of your writing. 

Is Grammarly for Business Worth It?

Grammarly Business is worthwhile if you have a large team and can benefit from the business-centered tools. It offers more features than the free Grammarly and Grammarly Premium versions and gives you the option to add unlimited devices with the Enterprise version. 

Grammarly Business is worth it if you need more than five devices or if you are managing a team of people. If you are not, then Grammarly Premium may be sufficient. 

For just occasional grammar checking without the benefit of a plagiarism checker, the free version of Grammarly is likely all you need. Determine your need, and remember that Grammarly has a too that will fit.
