Give a month, get a month

Invite friends to Stub and you both get Pro, free.

Every friend you bring to Stub earns you a free month of Pro — and there's no limit on how many friends you can refer.

How it works

Share your code or link. Open Stub, go to Reports → Refer friends, and copy your code or tap Share. Your link installs Stub and drops your code in automatically.
Your friend joins with it. When they enter your code, they get 30 days of Pro, free, right away — a full month to try everything.
You get a free month too. For your first friend, your month lands the moment they join. For every friend after that, your month lands when they subscribe to Pro.

Refer as many friends as you want — the more people who join through you, the more free Pro you stack up.

When your free months kick in

If you're on the free plan, your earned month starts immediately — full Pro for 30 days.

If you're already a Pro subscriber, your earned months are saved for you. They kick in automatically whenever you're not on a paid plan — so if you ever pause or your subscription lapses, your free months cover you before you're charged again. You never lose them.

Why "when they subscribe"?

Rewarding you when a friend actually becomes a paying subscriber keeps the program fair — it means real, engaged people, not throwaway sign-ups. So the best way to earn is simple: share Stub with people who'll genuinely use it.

The fine print

Referral codes are for new Stub users — someone who hasn't subscribed before.
Each account can redeem one friend's code, once.
You can't redeem your own code.
If a referred subscription is refunded, the matching reward is reversed.
