Retro Flash

Welcome to Retro Flash and the Arcade Bouldering Community!

Retro Flash is the Ultimate Spray Wall App, designed with every member of the climbing community in mind!

We have created a lot of unique tools to ensure that everyone has everything they need to get the most out of their spray walls!

For example, we support symmetrical, partly symmetrical, adjustable and private walls!

Set all kinds of problems on your wall, like circuits or even competition boulders!

With our wall upgrades, we upgrade your walls to the next level, opening up a lot of new possibilities!

Now, you can even upgrade your walls by yourself!!

Retro Flash supports the Fontainebleau, Dankyu and Hueco grading systems.

You can also define your own grading systems or even deactivate grading!
