EIGER is a mountain-planning app designed to help hikers and mountaineers prepare for their objectives with greater confidence. It combines information about individual peaks with expert-verified gear recommendations, helping users understand what equipment is needed for a mountain, season, and hike. Its catalog includes 97 mountains and more than 3,392 products, with gear mapped to specific requirements.

Users can store equipment in a Gear Vault and use the app’s compatibility tools to check whether their kit suits a chosen objective, including whether boots work with crampons and how warm their layers need to be. EIGER also provides terrain classifications that identify features such as glaciers, technical ground, and avalanche slopes, as well as summit-point forecasts and start-time warnings. Users can request peaks from a list of more than 48,000 named mountains, helping guide which ones the team verifies next.

Mountaineer Timoteo Desantos leads the human review of recommendations. EIGER is available on Android, with an iOS release described as forthcoming
