Questions

Short answers. No small print.

Who can join?

Anyone who reaches iOS developers or app makers: creators, writers, ASO experts, agencies and communities. Big or small, what counts is a good fit.

Do I have to be a customer?

No. But it helps: people trust a link more from someone who uses the tool.

When do I get paid?

Once a month, for payments that are at least 30 days old, so refunds don't count. Payouts start at $50, by bank transfer or PayPal.

What if a customer cancels?

You keep what you earned. Payments after the cancel, and refunded payments, earn no commission.

What about the 7-day free trial?

Trials count as yours. You earn once the customer starts paying, as long as they signed up within 60 days of the click.

Where do I see my numbers?

In your own partner dashboard: clicks, trials, customers and earnings. Until it is live, we send you your numbers by email every month.
