- A personal log to record completed climbs and mark favorite routes for quick lookup.
- Coverage of more than 80 sectors across Fontainebleau, including well-known areas like Cuvier and Franchard Isatis.
- Integrated mapping with GPS that helps you navigate to boulders and checkpoints.
- Filtering to help you discover problems that match your ability level and preferred grades.

Miscellaneous note
There was an unrelated reference in the original text about a “paid radio alternative for Cincinnati Bengals fans.” This appears to be extraneous and not connected to Boolder’s features.
