You can download Newton for Mac, Windows and Linux from account.newtonhq.com/get-the-app, and for iPhone, iPad and Android from the App Store and Google Play. Once it's installed, you sign in or create your Newton account.
Install Newton. On a Mac, open the downloaded .dmg file and drag Newton into Applications. On Windows and Linux, the button opens the Microsoft Store or the Snap Store, so install Newton from there.
Open Newton and click Continue after the introduction.
Sign in to your Newton account, or click Sign up to create one.
Tap Get Started to create your Newton account, or I already have a Newton account to sign in.
Good to know
The Mac app runs on Macs with Apple silicon or Intel.
You can also install Newton on Windows without the Microsoft Store, with the installer at account.newtonhq.com/download/win. If Windows blocks the installer, use the Microsoft Store instead.
Newton on Mac and the Windows installer version show a banner when an update is ready. The Microsoft Store and Snap versions update through their stores.
After each update, Newton downloads your mail again. This can take a few minutes.
