How it works
One: subscribe here. Secure checkout by Payhip.
Two: open PlanRef at app.planref.co.uk and tap Upgrade at the top right. Tip: add it to your home screen and it works just like an app, online or off.
Three: choose "Already subscribed? Sign in", enter the email you subscribed with, and tap Unlock. Premium is live in seconds, and your founding rate is locked for as long as you subscribe.
