The offer (from Opal's help centre):
- An invite code gives a new user a free month-long trial of Opal Pro
- The code's owner also earns a free month; 5 referrals earn a year, 50 earn a lifetime subscription
The limits — this page carried none of them:
- Only new signups qualify for the free month
- An account older than two weeks cannot be credited to a referral
- The referral system is iOS only — the Android and Mac versions do not support it, and Opal on Android is free anyway
What Opal is:
- A focus and screen-time app that blocks distracting apps during periods you set
- It rates 4.8 on the App Store from more than 150,000 ratings
How to use it:
- Install Opal through the link on this page
- Create a new account
- Enter PZW4F in the invite code field
- Check in the app that the Pro trial activated
Opal sets the terms and may change them. A subscription may renew automatically once the trial ends — read the terms in the app.
