An app made by a developer who is a mountaineer is definitely different!!
It perfectly understands the needs of real users.
It can change with the times.
It places more importance on the completeness of the app than on financial greed.
It does not add miscellaneous functions for profit, but goes all-in on mountaineering.
It may start small, but I promise that it will be reborn as a mountaineering one-tool app.
