Fantastic app for your home woodie

I am using this app for own home wall and little else but for the aforementioned task it gets the job done well.
One feature request would be to either add wall angle as a filter or that the search field also queries the description field so an angle could be added there. Currently I have to put the wall angle (my home wall is adjustable) in the name as a workaround.

Update : Thanks for the quick addition to the search field Christian! No more wall angles in boulder names! Great app!

Developer Response ,

Thanks for your feedback.
Filtering by the wall angle is a good point. Beside the description there is already a field called „wall angle“. I just included this field into the search in the boulder list of a location today. Should work now without an update of the app. The next update will add some info and add this feature to the favorite and ticklist as well. But for now it works in the boulder list of the location. Check it out 😉

I’ve been looking for an app like this for my home wall for a couple months. I was looking for info on the stokt app release when I stumbled into this. I couldn’t be happier! It does everything I had wanted and more and all at a fraction of the cost that I was anticipating for Stōkt. At a buck it’s a steal!!

Thank you very much for your great feedback. Have fun!

Good but could be better

Not many bugs, which is why we switched from EatSprayLove. However, a lot of clicking is required to navigated. Would prefer a library of problems to scroll through with less links rather than clicking back and forth through pages.

Developer Response ,

Thanks for using my app.
I'm working on a big update which enhances the usability a lot. I hope the release can be at the end of the year. Then you have a much better overview over the boulders and can access most of the functionality directly on a boulder without switching between the list and the details.
