After the trial, a GRT Pro subscription is only $57 per year. This gives you access to every tool on the GRT Calculator website:
- GRT for Email, a daily-use product that’s my personal favorite
- GRT for Websites
- GRT for Discourse
These tools provide similar results in different mediums: Your sizing and spacing is all optimized based on Golden Ratio Typography, and then you also have the ability to use GRT text formatting styles in each medium.
Put even more simply, I want to be able to execute every aspect of Attention Design wherever I compose text, and the GRT Tools help me do that.
