While there is no Windows app, Newton is available on iOS, Android, and macOS, including Android Wear and Apple Watch.

Cons
Con Subscription based
Newton costs $49.99 per year after the 14 day free trial.
Con It's "stupid expensive"
$49.99/year? Really? And it doesn't cook, clean, or serve beer. There are better email apps for far less money.
Con Javascript-intensive Webmail
Free accounts are required to use Javascript webmail and encryption is done in the browser. Javascript cryptography is harmful for security and should not be used.
Con Encryption Keys are stored server-side
The keys are generated during account creation. Using your existing keys is prohibited and ProtonMail must store and control the private keys. Encryption cannot be secure unless the user controls the private keys.
Con Still lacks some useful features
At the moment, there is no calendar feature and contact management is quite poor. They will, however, start to work on it.
Con Ties to US Investors
ProtonMail takes money from US Investors
Con No IMAP and SMTP support for basic accounts
Basic accounts are restricted to the Protonmail web client. Support for IMAP and SMTP is available with a paid subscription only, and as such with basic accounts it is not possible to send and receive email with external applications.
Con Overly expensive for desktop support
Con Requires phone number for login
If you sign up over Tor or a VPN, it will require email or phone number verification. Email verification is disabled if you use an email that isn't from Google or Outlook.
