Steps

The "Install LotJitsu on your mobile device" email
If you created your account on a computer, LotJitsu emails you a few hours after you verify your email address, with the subject "Install LotJitsu on your mobile device". Open it on your iPhone and tap Start App Setup to reach the download buttons. You don't get this email if you have already logged in to the app.
Opening app.lotjitsu.com in Safari
The web version of LotJitsu does not run in a phone's browser. If you open app.lotjitsu.com on an iPhone, you see a Download the App page with the store badges instead. Use the app.
With the app installed, tapping a LotJitsu link in an email, such as a verification or password reset link, opens the app.
