It's free to install the app and try all template designs, so you can customize and test as many designs as you like before making up your mind.
Once you are happy with your design, your 1st template is just $29. This is a one-time fee, and there is no subscription or ongoing costs.
Any additional template (2nd, 3rd etc) you purchase, gets an automatic 50% discount applied.
You can log back into the app at anytime (before and after purchase) to update your templates as needed.
