I created an Android app during free time main idea is to create simple tool which is working offline too.
Basic Idea have all 7 classes and skill trees which is display basic descriptions and some synergies.
You able to make and save your build to favorites. Also you can share those builds with other users.
Copied from clipboard code is base64 encoded text and you can encode and see class, skills from left to right moving from tab1 and row by row.
basically 30 numbers you can change and then encode to base64 to make custom code with some online tool if you need it
But basically is oriented to Mobile phones and if you need share you simple send code to your friend which will open your build in his phone ofc need an App install and import to app your build. Play Store Diablo 2 Skill Calculator
