I built a referral campaign for my app that helped me double my sign ups in a week!

We created for one of our apps, the following referral campaign - https://www.withhislight.app/mydevo/?name=Ben&ref=Peadar&appId=WHL

What problem does this solve?
Paid ads costs have gone up in recent years and getting distribution for your app or course is hard. How about you encourage word of mouth?

What is it?
You can simply write your name and share it with others. For this I shared it with my friend Ben.

What use cases are there?
If you've any product that you're promoting, that friends sharing to hear their name would be useful. So courses are a good example, but could also be e-commerce say.

If anyone would like a free sign up to add this to their course or app let me know in the comments :)
