obsidian is a great app and they have an excellent mobile client. if you ever want to explore the structural components of Dendron while using Obsidian, you can as we interop on most features
This is a huge part of what led me to adopting Dendron (and eventually contributing to and working on the project): the importance of interoperability. Seeing progress being made toward importing docs from Google docs, importing content from GitHub issues, adding other public vaults into my local workspace (like the TL;DR docs seed), etc. were great.
