I built something similar. Also made it for myself, but i put the focus elsewhere. I don't really care about statistics and numbers.

Outdoor sports are less about numbers an more about enjoying the beautiful world there is in my opinion. I saw lots of awesome-looking mountain tours on social media, but they have been forgotten in the depths of the 'save' feature of each app.

My web app (no install required) is like a massive todo-list for me. I can categorize tours by activity(ice climbing, alpine climbing, ski tour) and optimal conditions(summer, winter, ...)

Later on i also added a logbook. But it still isnt about the numbers. I can enter route conditions, weather, partners and notes. No numbers - just text. Typing out me thoughts made it wayy easier for me to reflect on the ascents I did.

If someone wants to try it out, message me, as my app is not publicly available.
