Boulder Blitz

Built for Tension Board, Boulder Blitz replaces the manual grind of setting a timer, hand-picking a problem on the app, and tallying your own attempts. Link your existing Tension account, set your session, and go.

SOLO MODE
A configurable interval timer for training alone — set a game mode (rapid, blitz or bullet depending on how fast-paced a session you're after), number of rounds, number of climbs, climbing grade and board angle. Boulder Blitz keeps you moving between climbing and resting with clear countdowns and sound cues.

DUEL MODE
Head-to-head, on the same board. Two players alternate attempts on the same randomly-selected climb, so it's a genuine duel rather than two separate sessions compared afterward.

AUTOMATIC CLIMB SELECTION + BOARD LIGHTING
Boulder Blitz picks a climb from your board's own catalogue and lights it up directly on your Tension Board over Bluetooth — no scrolling through the Tension app between rounds.

SESSION HISTORY
Completed sessions are saved to your account, so you can look back at what you climbed, your scores, and how many rounds you completed.

WHAT YOU NEED
- A Tension Board and an existing Tension account (used only to fetch your board's climb catalogue and control its lights — see our privacy policy for details)
- Bluetooth enabled on your phone, within range of the board

No ads. No analytics or tracking SDKs. Your data is used to run your sessions — nothing more.
